2.5 Edge preparation: 2.5.1 Butt Welding Fittings: Unless otherwise specified , the butt welding fittings shall be

supplied with edge preparation for welding with the connecting pipe. The edges shall bemachined as per ASME: B16.25.

2.5.2 Socket Welding/Threaded Forged Fittings: Unless otherwise specified, the forged

fittings shall be machined as per dimensions and tolerances specified in ASME B 16.11. 3.0 RAW MATERIAL: 3.1 The raw material for the fittings shall consist of killed steel forgings, bars, plates,

seamless tubular products, conforming to the chemical composition requirements of theapplicable finish product specification and material grade.

3.2 It is the responsibility of the supplier to select the appropriate raw material so that all

the pipe fittings meet the dimensional & other requirements indicated in this standard. 3.3 All the plates used for manufacturing of fittings shall be ultrasonically tested by either

of the following: i) ASME SA 435 and acceptence standards as in SA 435 except that adjacent

discontinuity indications shall be seperated from each other by a distance equal to orlonger than the larger of the indications, unless both the adjacent defects can becontained in a circle of diameter equal to the acceptance standards of a single defect.

ii) ASME SA 578 and acceptance standard shall be as per level -C of SA 578.

marks. 6.0 CERTIFICATION: 6.1 All fittings shall be delivered along with three original copies of test certificates in

english as per the format enclosed in Annexure - 1. 6.2 IBR CERTIFICATION:

All the carbon and alloy steel pipe fittings pertaining to the material specifications:ASME: SA 234 Gr WPB, Gr. WP11, Gr. WP22; Gr. WP91; ASME SA 105 and ASME SA 182 Gr. F11, F22 & F91 shall be supplied under inspection and certificationby IBR or by an inspection agency approved by IBR. The test certificates shall beprovided in IBR format, form III C (i.e. in addition the test certificates to be furnished as per annexure-1, annexure-2 & annexure 3).

6.3 In addition to the requirement specified at 6.2 above, all the pipe fittings supplied as perthis specification shall be inspected and certified by BHEL nominated inspectionagency at the manufacturer's works. Scope of inspection shall be as per BHEL approvedquality plan.

a) Vendor shall ensure strict Quality Assurance Process while selecting the source of Raw

Materials & their procurement methods. Vendor shall produce documentory evidencesaccordingly of its QA process ensuring the correct sourcing - at any time to BHEL's inspection agency. It shall be the responsibility of the vendor to ensure that no mix up ofmaterials & their identification occurs during all stages of procurement, marking, transport,stocking at its works & also before starting of the manufacturing.

b) All steps shall be ensured by the vendor so that only required materials as perspecifications are only made input to manufacturing process, kept documented processassurance methods during total cycle of manufacturing, Heat-Treatment, surface treatment, testing & final painting/marking/colour coding.

9.0 MARKING, PRESERVATION AND PACKING: 9.1 Marking: The following details shall be punched on each fitting.

a) Manufacturer’s name or trade mark. b) Type of fittings. c) Item designation (as per ordering specification). d) Material specification grade. e) Melt No. f) Test certificate number. g) Mark of Inspection Authority. h) BHEL Des no. (As indicated in P.O./intimated from BHEL).

9.2 Preservation: Before despatch, the fittings shall be dried and cleaned and the entire

surface shall be well coated with a good quality rust preventive coating that will notbecome fluid and run-off at 65°C.

9.3 Packing: All fittings shall be provided with suitable HDPE End Covers to protect the ends

(socket/threaded ends or weld edge preparation) and to protect the internal surfaces. Allfittings shall be packed and despatched in suitable wooden boxes, so that no damagesoccur during transportation/storing.

10.0 COLOUR CODING:

All the pipe fittings shall be colour coded by painting a circumferential ring of 10 mm width at one end of the fitting at a distance of 20 mm from the end. The colour of thecircumferential ring shall be according to the applicable material grade as given in the tablebelow.

TEMPERATURE STUB, SCREWED TYPE, FOR MEDIUM PRESSURE(UP TO 250 Kg/cm2)

1.0 SCOPE:

1.1 This standard specifies the requirements of temperature stubs for nominal pressure up to 250 Kg/cm2, for slant immersion for main pipe O.D’s 88.9 to 159 mm and for straight immersion for main pipe O.D’s of 168.3 mm and above with carbon steel and alloy steel materials.1.2 These stubs are used for insertion of thermowells of temperature measuring instrument for media demineralised water, oil, fuel gas etc.

2.0 DESIGNATION: A temperature stub for straight immersion carbon steel material length 45 mm pressure 250 kg/cm2 to this standard shall be designated as follows.

2.1 On Drawings and Indents :Material specification column : AA 732 61 02

Description column : TEMP. STUB STRT IMRTN CS L45Material code column : AA 732 61 02 341

2.2 On Enquiries and Purchase orders: In addition to incorporating the above details, a copy of this standard shall be enclosed.

3.0 TECHNICAL REQUIREMENTS:3.1 Materials: The stubs shall be manufactured from forged materials as given below:

Material Service temp. Specification Carbon steel 0 – 427o C ASTM A 105 Alloy steel 427 – 538o C ASTM A 182 F 11 427 – 593o C ASTM A 182 F 22

3.2 The dimensions of temperature stub for slant immersion are given in table 1. These stubs are used for main pipe O.D’s of 88.9 to 159 mm.

3.3 The dimensions of temperature stub for straight immersion are give in table 2. These stubs are used for the main pipe O.D’s of 168.3 mm and above.3.4 For installation of thermowells in pipe O.D’s 88.9 mm below, larger pipe section of O.D

88.9 mm should be used. The mounting details are as given in Annexure 1.3.5 The treading connection of the stub is M33 x 2.
