Boiler Steel Pipe

Name: Boiler Steel Pipe
Brand: Cangzhou Silver Valley technology Co., LTD

Boiler steel pipes are special steel tubes used to manufacture boilers. They are mainly used to transport high-temperature and high-pressure water, steam or other media. The material must have good heat resistance, pressure resistance and corrosion resistance. Common materials include carbon steel, alloy steel and stainless steel. Boiler tubes are widely used in power, chemical, petroleum and other industries, and are key components in boiler equipment.

What Is Boiler Steel Pipes/Tubes?

Boiler steel pipes are pipes used to transport media in boilers. They connect various parts of the boiler to achieve effective heat transfer. They are made of carbon steel, alloy steel or stainless steel, depending on the temperature, pressure and chemical properties of the transported medium.

Seamless boiler tubes refer to boiler steel tubes without welds made by hot rolling or cold drawing. During its manufacturing process, the steel billet is formed into a tube through perforation, rolling and other steps, ensuring the integrity and uniformity of the tube.

Seamless boiler tubes have higher strength, pressure resistance and heat resistance, and are suitable for high temperature and high pressure environments. They are often used in boilers and heat exchanger equipment in the power, chemical, petroleum and other industries.

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”.
