Steel Pipes
We are well known importers and dealers of quality Steel Pipes in India.
Types of Steel Pipes
• CARBON STEEL PIPES: Seamless/ERW Pipes - A 106 Gr.B, API 5L GR.B, ASTM A210 A1, SA 179 ETC.
• ALLOY STEEL PIPES: ASTM A - 335 GR.P11, P22, P91. ASME SA - 213 T11,T22,T91
• STAINLESS STEEL PIPES: Seamless and Welded Pipe- 304, 316, 321, 317, 310
Specifications / Features
• ASME specifies a set of Alloy Steel pipe specifications which can be welded - Welding rod Specification is : E.8018.
• Standard pipe schedules are available like sch 20 , sch 40 etc with 60.3 mm O.D x 3.63 mm thick pipe outer diameter
• Pipes have negative tolerance which will be considered at the stage of designing [negative tolerance means variation in thickness up to a maximum of 12.5% to be checked from ASME SEC viii DIV-1]
• Pipes have a outer diameter ranges from 25 mm to 400 mm & thickness range from 2.53 mm to 25 mm
Applications
The Steel Pipes find applications in
• process heating like boiler/chemical industries/paper, if the temperature exceeds 450 oC and within 550 oC.
• pipe welding
• boiler quality alloy steel can be efficiently used for headers, risers, main steam lines etc.
• root run can be tig welded using alloy steel tig wire.
