A333 Seamless & Welded Steel Pipe

A333 Seamless & Welded Steel Pipe

→

ASTM A333 is the standard specification for seamless and welded carbon and alloy steel pipe for low temperature applications or other applications requiring notch toughness. This standard covers several grades of ferritic steel: Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10 and Grade 11.

A335 Seamless Steel Pipe

A335 Seamless Steel Pipe

→

ASTM A335 steel pipe may be hot finished or cold drawn and subjected to the following finishing heat treatment. The specification covers "chrome-molybdenum" seamless pipes with excellent corrosion resistance and high temperature tensile strength. Generally, ASTM A335 P11, P22, and P91 pipelines are used for power generation and downstream oil and gas, and P5 and P9 grades are used for refinery applications.

GB/T8162 Seamless Steel Pipe

GB/T8162 Seamless Steel Pipe

→

Seamless steel pipe for general structure (GB/T8162-2008) is a seamless steel pipe for general structure and mechanical structure.

DIN 17175 Seamless Steel Pipe

DIN 17175 Seamless Steel Pipe

→

DIN 17175 is suitable for seamless pipes and is used in the construction of boilers, pipelines, pressure vessels and equipment. The maximum temperature can reach 600 ℃. At the same time, under high pressure, the total stress and related fouling conditions can increase or decrease the temperature limit.

DIN 1629 Seamless Steel Pipe

DIN 1629 Seamless Steel Pipe

→

DIN 1629 seamless steel pipe its main grades are St37.0, St44.0, St52.0, DIN 1629. Generally, the DIN 1629 standard is not limited to the working pressure value, and the working temperature is limited to below 300 ℃.

EN 10210/S355 Seamless Steel Pipe

EN 10210/S355 Seamless Steel Pipe

→

Grade S355 is a low carbon manganese-containing steel alloy. This medium-strength carbon steel has both good weldability and good impact resistance. Grade S355 steel is also well suited for sub-zero temperature applications.

EN 10219/S235 Welded Steel Pipe

EN 10219/S235 Welded Steel Pipe

→

EN 10219 standard is used to produce pipes, and cold-formed steel pipes EN 10219 S235JR are very suitable for welded structures.

Spiral Submerged Arc Welded Pipe SSAW

Spiral Submerged Arc Welded Pipe SSAW

→

The spiral submerged arc welded pipe is made of hot-rolled steel strip as raw material, and is usually made by constant temperature spiral forming and automatic submerged arc welding. The manufacturing process is to roll the steel strip, make the rolling direction at a certain angle to the center direction of the tube, and then form and weld, so the weld is spiral. Can provide API SPEC 5L steel pipe, GB / T3091,GB / T9711-2011,EN10219,ASTM A252 standard steel pipe.

LSAW Pipe

LSAW Pipe

→

The longitudinal submerged arc welded pipe is made of steel plate as raw material, which is formed by a forming machine, and then double-sided submerged arc welding is carried out. Through this process, the LSAW pipe will have excellent ductility, toughness, uniformity, plasticity and good sealing performance. The production equipment can be produced quickly, easy to replace, and the product specification range of LSAW pipe is large. The production line can produce welded pipe diameter 406-4500mm, wall thickness 8mm-100mm.
