1 Seamless Tubes and Pipes for Power Plants

2 Seamless tubes and pipes for Power Plants Features 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. Definition of the order Ordering Information - Norms and specifications - Steel grade and heat treatment - Sizes, minimum or average wall thickness - Lengths - Quantity - Surface finishing - Inspection Options: a) Fixed or multiple lengths b) Special tolerances c) Special tests d) Surface protection e) Special marking f) Colour coding g) Special packing Reference standards EN - ASTM/ASME - DIN -NF A - BS -UNI - ISO - GB GOST - JIS Steel grades Carbon steel; alloy steel (i.e.t/ P11, 13CrMo4-5, T/P22, 10CrMo9-10, 15NiCuMoNb5-6-4, T/P23); high alloy steel (i.e.t/p91, T/P92); stainless steel (TEMPALOY AA-1, TEMPALOY A-3 ) Certification The products are supplied with 3.1 test certificates, according to EN Certification according to 3.2 can be agreed at the time of order. Identification and marking All 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. Packing Pipes 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 inspections Main 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 qualification Tenaris has been approved by various inspection bodies, TÜV - L.R. - etc. Homologations: - TÜV: AD W 0 - TRD PED 97/23/EC - IBR Tenaris applies a Total Quality Assurance programme in compliance with ISO 9001

Surfaces Tubes 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. Other type of surface finishing may be agreed at the time of order Size range See table (page 6). EXAMPLE OF ISOTHERMAL CURVES FOR CREEP RUPTURE DATA STRESS [N/mm 2 ] C 550 C 600 C tubes and pipes operate at very high pressures and temperatures for long periods of time. The pressure load combined with the high service temperatures produces a slow but continuous microstructural variation of the steel, causing a progressive reduction of the properties of the material itself: this phenomenon is called Creep. Since 1957 TenarisDalmine has been conducing studies on this topic in cooperation with recognized international R&D laboratories. 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 characterizations on all the boiler materials, with single tests reaching durations of more than hours. Tenaris performs deep analyses on the microstructural evolution, in order to verify the long term stability of the materials in service conditions. 35,0 38,0 40,0 42,4 44,5 48,3 52,0 54,0 57,0 60,3 63,5 70,0 73,0 76,1 82,5 88,9 101,6 108,0 114,3 127,0 133,0 139,7 141,3 152,4 159,0 168,3 177,8 193,7 219,1 244,5 273,0 323,9 355, ,4 457,0 508, , TIME [Hours] 610,0 660,0 711,0 812,0 914,0 1016,0 1118,0 Steel grades from Carbon up to 10CrMo5-5 (T/P11 according to ASTM A 213/A 335) grades higher than 10CrMo5-5 feasibility ranges can be different; please contact Tenaris Technical Department Upon request, provided by Third Parties 0,079 0,091 0,102 0,114 0,126 0,142 0,157 0,177 0,197 0,220 0,248 0,280 0,315 0,346 0,394 0,433 0,492 0,559 0,630 0,689
