Product Detail

Product Tags

Our company is mainly engaged in steel pipe export business  Alloy Pipe Boiler, Carbon steel tube, China Seamless Steel Tube, Pipe Boiler, Pipe Boiler China, SMLS Pipe Boiler.

Boiler steel pipes includes medium pressure boiler pipe and high pressure boiler pipe, it is often manufactured in seamless procedures, welded steel pipe is not applicable.

It has been widely used at heat exchanger pipe and tubing services, tube exchanger bundle, high pressure boiler, economizer, super heater, petrochemical industry pipes, etc.

Boiler pipe materials and standards
Standards and material for steel pipe is available at carbon, alloy, and stainless steel material.
Carbon steel: ASTM/ASME A/SA 106, ASTM A179, ASTM A192, ASTM/ASME A/SA 210, ASTM A333 Gr 1, 6,7 to Gr 9,
Alloy steel: ASTM/ASME A/SA 213 T1, T2, T5, T9, T11, T12, T22, T91, T92; ASTM A335 P1, P2, P5, P9, P11, P12, P22, P91, P92
Stainless Steel: ASTM A268, ASTM A213, TP304/L, TP316/L, 310S,309S,317,317L,321,321H, and duplex stainless steel material etc.
Common Sizes: OD from 6mm to 1240mm, thickness from 1mm to 50mm
Types: Straight boiler pipe, and U boiler steel pipe for tube exchanger bundle.
These standards specify the classification, size, shape, weight and allowable deviation, technical requirements, inspection and test, packaging, marking and quality certificate of seamless steel tubes for boiler.

Boiler Pipe Size
Boiler pipe size range complied with the different ASTM standard required. Like ASTM A106 or ASTM 179, 192 etc.

But most of the boiler pipe size is small, outer diameter usually less than 1 1/2” (1/4”, 1/2”, 3/4”, 1” and 1 1/2”). Then 2”, 2 1/2”, 3” and maximum to 4”.

Today, We have been with great passion and sincerity to further fulfill our global customers’ needs with good quality and design innovation. We fully welcome customers from all over the world to establish stable and mutually beneficial business relationships, to have a bright future together.
