CertificationThe products are supplied with 3.1 test certificates, according to EN 10204.Certification according to 3.2 can be agreed at the time of order.

Identification and markingAll products are identified in accordance with the material Specification and/or in accordance with P O requirements (to be agreed). Special specific marking to be agreed.

PackingPipes may be furnished bare or coated and with capped ends. Tubes and pipes up to 3” OD will be supplied in bundles. In order to prevent rust during sea shipment, bundles of tubes may be wrapped with polypropylene sheets, and secured with flat steel bands. Over 3” OD will be supplied loose.

Tests and inspectionsMain tests performed:- Heat analysis- Product analysis (when

applicable)- Tensile test at room

temperature- Tensile test at elevated

temperatures (when applicable)- Impact test (when

applicable)- Hydraulic test or equivalent

NDE- NDE- Visual and dimensional

inspection- PMI- Technological tests (when

applicable)

Multi Lead R ifled seamless cold drawn tubes for boiler are available upon request.

Specific qualificationTenaris has been approved by various inspection bodies, TÜV - L.R. - etc.Homologations: - TÜV: AD W 0 - TRD 100- PED 97/23/EC- IBR

Tenaris applies a Total Quality Assurance programme in compliance with ISO 9001

The boiler tubes and pipes are manufactured with materials able to withstand high temperatures and high pressures. These materials must meet the most stringent technical requirements for production process and inspection tests in order to guarantee their durability and reliability over the whole service life.

Features

Seamless tubes and pipes for Power Plants

Seamless hot finished tubes and pipes for utility boilers, industrial boilers and heat recovery steam generators

Lengths The tubes and pipes are supplied in random lengths or in fixed lengths to be analysed and agreed at time of order, in the range between 4,000 mm and 26,000 mm depending on the size.

SurfacesTubes and pipes will be supplied in accordance with the standard workmanship as per hot finished products.Special surface protection may be agreed at the time of order.

Notes on the behaviour of steel at high temperatures

Boiler tubes and pipes opera-te at very high pressures and temperatures for long periods of time. The pressure load combined with the high service tempe-ratures produces a slow but continuous microstructural variation of the steel, causing a progressive reduction of the properties of the material it-self: this phenomenon is called “Creep”.Since 1957 TenarisDalmine has been conducing studies on this topic in cooperation with reco-gnized international R&D la-boratories. It is member of the European Creep Collaborative Committee and participates in European R&D programs on boiler materials.

Its creep laboratory conducts extensive studies and characte-rizations on all the boiler mate-rials, with single tests reaching durations of more than 100000 hours. Tenaris performs deep analyses on the microstructural evolution, in order to verify the long term stability of the mate-rials in service conditions.
