    OneSteel is Australias largest distributor of Pipes, Pipe Fittings, Valves and associated accessories.The OneSteel distribution network offers more than 100 outlets throughout Australia, comprising:

    OneSteel Piping Systems Capital cities and selected regional centres

    OneSteel Fire Systems Capital cities, specialising in fire and associated plumbing services

    OneSteel Metaland Regional cities and towns in all states

    The "Pipe Fittings" catalogue is part of a comprehensive series of catalogues, brochures and datasheets which are provided to our customers and associated industry groups. This cataloguedescribes our range of pipe fittings which are principally manufactured in carbon steel, cast ductileiron and malleable iron. A separate catalogue describes our range of stainless steel pipes and fittings.

    In Australia we have two broad groups of standards which govern the design and manufacture of ourproducts, viz:

    British / Australian Standards Generally covering cast iron and mild steel fittings for low-to-moderate pressures, for commercial and light industrial applications. In this group we also offer selected products to DIN standards.

    American Standards Generally covering carbon steel and alloy steel fittings for higher pressures and temperatures and typically used in the oil, gas, chemical and heavy processing industries.

    Our customers tend to work predominantly with one standard or the other. For your convenience wehave grouped most of the products accordingly. The detailed contents are shown on the opposite page.

    For further information please contact your local OneSteel sales office. Details of our locations maybe found on our website at www.onesteel.com.au.

    Our catalogues are provided for your assistance. However we are obliged to draw your attention tothe following:

    MATERIALSBlackheart Malleable Iron castings.

    DIMENSIONS generally to ASME B16.3 or JISB2301, depending on manufacturing source. JIS B2301dimensions are generally considered to becorresponding values to BS143 and BS1256, althoughsome sizes are not exact equivalents.

    THREADING is BSP pipe thread, to BS.21(AS 1722, Part 1).The specification for BS 143 fittings is:Taper External (Series R) Taper Internal (Series RC)The specification for BS 1256 fittings is Taper External (Series R) Parallel Internal (Series RP)Our stock fittings are usually BS 143 taper/taper, asthis is believed to offer superior sealing characteristicsdue to greater thread contact (refer illustration below).Taper/taper threads are also being specified byincreasing numbers of Gas Authorities, for the samereason.

    Parallel Threaded Fitting: Taper Threaded Fitting:Taper Threaded Pipe Taper Threaded Pipe

    ALTERNATIVE THREADING to special order.

    NPT (API linepipe threads) Taper Internal/TaperExternal can be supplied for fittings to AmericanspecificationANSI B16.3.NOTE: Locknuts and Plain Sockets without ribs, aresupplied with parallel threads.

    FINISHHot Dip Galvanised is the standard finish for stock.

    TESTINGFittings shall be subject to an internal hydraulicpressure of 2068 kPa without showing any sign ofleakage or abnormality.

    WORKING PRESSURES (except flanges)Recommended maximum working pressures are 1379kPa for water and 1034 kPa for steam, air, gas and oil.NOTE: Working pressures may also be limited byrelevant Pressure Piping Codes or Industry regulations.

    UNEQUAL SIZESWhen ordering Reducing Sockets, Nipples, Bushesand Elbows, always state largest size first e.g. 80 x 40 bush.When ordering 3- or 4- way fittings, the sizingsequence illustrated below should be adopted.

    I.S.O. METRIC HEXAGON STEEL BOLTS FOR USE WITH AS. 2129 FLANGESSteel Hexagon Bolts and Nuts (XOX) are recommended for use within a temperature range of -50C to +300C.Outside of this temperature range, Stud Bolts should be used as recommended in AS. 2528.A quick reference chart for sizing bolts and nuts for a range of regularly used standard flanges is given below.

    APPLICABLE TO PLATE AND FORGED STEEL LOOSE FLANGES ONLYNOTE: Integral valve flanges quite often differ in thickness to equivalent loose flanges.

    When integral flanges are involved due allowance should be made to bolt lengths.

    Bolt lengths listed apply to flat-faced or 1.6 mm raisedface flanges with allowance for 1.6 mm gasketthickness.

    * For approximate Stud Bolt Lengths take the XOX BoltLength and add the metric diameter in mm rounded tothe nearest 5 mm increment up.NOTE: This does not include length of point.

    STAINLESS STEEL: Fittings (Grades 304 and 316, also 304L and 316L) are equal to stainless steel pipes toASTM A312 of equal grade and schedule.NB: Stainless Steel Fittings in Schedule 10S and 5S are not designed for applications where pressure is a primeconsideration, and the relevant standard, MSS SP43 establishes the working pressures substantially lower than thoseyielded by the application of the basic formula.

    QUALITY CONTROLButtweld fittings from OneSteel are subject to strict quality control. Manufacturers plants are visited regularly, and thesource of mother tube is verified. Test certificates are available as required. OneSteel liaises with major customers toensure that all fittings are obtained from sources approved by the customer or by specific industry groups.

    WELDOLETSUsed to make full size and reducing branch connections from 6 to 750mmfrom run pipes 10 to 900mm in order to:

    Facilitate header construction. Construct the joint to full pipe strength. Meet code design requirements for reinforced branch joints. Improve flow. Assure economical, clean and strong connections.

    THREDOLETS AND SOCKOLETSUsed for making relatively small branch outlet connections.Threadolets and Sockolets are half couplings that are bevelled for convenience,tapered for strength, flared for fluid flow and drop forged for theultimate in strength and ruggedness.

    ELBOLETS AND LATROLETSUsed for making threaded, socket-weld or buttweld outlets tangentially to elbows oras 45 branch connections on straight pipe. The design provides for a full penetrationweld. These fittings provide greatly improved flow conditions compared with 90connections and are advantageous for many instrument connection applications.

    INSTALLATION GUIDELess fit up time is required for Olets than formost other fittings or fabricated connections. When properwelding procedure is followed, the resultant cost is moreeconomical than constructing branch connections by anyother method.

    HOW IT WORKSEach outlet size indicated on chart is designed to fit a number of run pipe sizes, E.G. The 15mm fitting marked900-100x15 will fit all run pipe sizes from 100mm to 900mm. When placed on a 900mm run pipe, there will be amaximum gap of 1.6mm between the top of the run pipe and the base of the fitting at the crotch as shown on sketch.This gap is negligible when welding.

    Screwed Fittings are taper-threaded in accordance with ASME B1.20.1, having thread lengths in accordance withapplicable tables.

    The actual and theoretical axes of the threads may diverge by not more than 1.6 mm in 300 mm.

    Fittings can be threaded to British Standard Taper (BS 21) if required. ASME B 1.20.1, the American Standard forpipe threads, determines length of thread engagement as shown below.

    Socket-Weld Fittings are designed for welding to American standard pipes (3000 lb. fittings to Sch. 80 pipeand 6000 lb. fittings to Sch. 160 pipe). The standard does not give dimensions for socket-welding 2000 lb. fittings.

API 605 dimensions DO NOT match ASME, MSS or BS dimensions ofsimilar pressure class.

    AWWA C207-54TThis is a Standard published by the American Waterworks Association for steelFlanges to be used on waterworks and sewerage pipes. These flanges matchClass 125 Cast Iron Flanges (ASME B16.1) in most dimensions.CLASSES 125LW, 175 & 350These are Standards developed over the years by a number of manufacturers, not allusing exactly the same dimensions.

    TEMA FLANGESThe Tubular Exchangers Manufacturers Association (TEMA) lays down standards fordimensions and material specifications for Shell Flanges, Cover Flanges, Long WeldingNecks for Nozzles and other heat exchanger components.

    BS.3293This British Standard established dimensions for flanges for petroleum industry use,in Class 150, 300, 400 and 600, in sizes above 600mm, which correspond exactly to thoseof MSS SP-44 in Class 300, 400 and 600.Class 900 is not included in the British Standard, but dimensions are given for Class 150,600-700mm which are similar to those of ASME B16.1, Class 125.

    ANSI FLANGESMATERIAL SPECIFICATIONSAmerican Standard Pipe Flanges are manufactured in avariety of Carbon, Alloy and Stainless Steels and selection ofa particular grade is determined by the usual criteria ofpressure/temperature requirements and corrosion resistance.Since these factors determine pipe and fittings to be used in apiping system, it is then necessary only to select flanges of asimilar material.

    The classifications are used to group materials for Flanges Class 150through Class 2500.

  • WELDING NECK FLANGESThis type of flange is attached by buttwelding to theadjoining pipe or shell. The weld may be made eithermanually or automatically with or without a backing strip.Sound welds are readily obtained with any recognisedwelding procedure.

    THREADED FLANGESThreaded flanges are, of course, attached by screwing tothreaded pipe ends.

    SOCKET-WELD FLANGESIn attaching socket-weld flanges, the pipe end isinserted into the socket and then welded at the flangehub. An inside weld at the pipe end is frequently madefor greater strength or, with grinding, to provide asmooth bore without pockets or recesses.

    METHODS OF ATTACHMENT

    SLIP- ON FLANGESAlthough recommended practice in attaching Slip-Ontype flanges is to weld both at the flange hub and thepipe end, for mild service conditions only one issometimes employed. In this case the weld is normallymade at the pipe end.

    LAP JOINT FLANGESLap joint flanges are most frequently used with lap jointstub ends, (Type A), although in some cases the lap isformed on the pipe end. Since they are free to rotate orswivel, there is no problem of bolt hole alignment. Suchjoints may be readily broken for inspection, cleaning,etc. The radius at the ID of the flange faceaccommodates that at the back of the lap, thuspermitting more uniform application of loading.Lap Joint flanges find their most common applicationwhen used with stainless steel stub ends.

    OneSteel stocks Type B stub endswhich are used with normal slip-on weld flanges -

    ie Lap joint backing flangesare not required.

  • GASKET SURFACEFlanges, and other products designed for bolted connection, when furnished with raised face (or flat face) may have anytype of gasket surface finish that is required. The more common finishes are described in the following paragraphs.

    1 STOCK FINISH:This is a continuous spiral groove. Fornominal sizes 300mm and smaller it isgenerated by a 1.58mm radius round-nosed tool at a feed of 0.79mm perrevolution. For sizes above 300mm thetool nose is radiused to 3.17mm and thefeed is 1.19mm per revolution.

    NB OneSteel stocks flanges withsurface finish in the range3.2-6.3 microns, ideal for usewith both spiral-wound andring gaskets.

    4 SMOOTH FINISH:This finish, which can be produced byseveral shapes of tools, shows nodefinite tool markings apparent to thenaked eye. In the past this finish wassometimes known as Smooth Plane.This term however, should be avoidedbecause of a tendency to confuse it withflat faced which, of course, applies tothe flange facing and not to the gasketsurface finish.

    2 SPIRAL SERRATED:This too, is a continuous spiral groove,but it differs from the stock finish in thatthe groove is generated with a 90included angle V tool. The groove is.39mm deep and the feed is .79mm forall sizes.

    5 COLD WATER FINISH:Produced by using a wide tool at highspeeds, this finish is equivalent to that ofa ground surface. It is mirror-like inappearance and surfaces finished in thismanner are usually expected to be usedwithout gaskets.

    3 CONCENTRIC SERRATED: (Not illustrated)As the name suggests this surfacefinish is made up of concentric grooves.A 90 included angle V tool is usedand the grooves are .39mm deep and.79mm apart.

    AMERICAN STANDARD FACINGS To ASME B.16.5

    *It is necessary to modify facing dimensions in order to furnish slip-on flanges 40mm and smaller and welding neckflanges with bores larger than Schedule 40, in sizes 40mm and smaller, for large tongue and groove facing.

  • ORIFICE FLANGESOrifice Flanges are used to locate an orifice plate in a pipeline and to provide a tapped opening upstream anddownstream of the plate.The tapped openings are connected to pressure recording instruments and the pressure differential between theupstream and downstream readings is translated into a measurement of flow in the line.Orifice Flanges are always supplied in pairs or sets and are available with slip-on, weldneck or threaded connections.To facilitate the insertion and removal of orifice plates, the flanges are provided with a set of jacking screws.By backing off the flange bolts and tightening the jacking screws, the flanges are forced apart, allowing access to theorifice plate.Orifice flanges are available from all OneSteel branches. Orifice plates can also be supplied to customer requirements.Please contact your OneSteel Sales Office for further details.
