ASTM A106 is suitable for seamless carbon steel pipe for high temperature environment. ASTM A106 pipe is manufactured according to grade A, B and C. A106-A is equivalent to the domestic 10# steel material, A106-B is equivalent to the domestic 20# material, is a relatively common use of a steel pipe material at home and abroad. A106 seamless steel pipe is mainly used in construction, mechanical processing, electrical, petrochemical and other industries.
A179 seamless cold drawn low carbon steel pipe is equivalent to China's No. 10 high-quality low-carbon steel. A179 is suitable for cold-drawn high-quality low-carbon seamless steel pipes for heat exchangers and condensers.
A53 Seamless & Welded Carbon Steel Pipe
ASTM A53 is a carbon steel alloy that can be used as structural steel or for low pressure piping. ASTM A53 (ASME SA53) carbon steel pipe is a specification covering seamless, welded black and hot-dip galvanized steel pipe from NPS 1/8 "to NPS 26. A53 is suitable for pressure and mechanical applications, as well as for general use in steam, water, gas and air lines.
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.
A252 Seamless&Welded Pipe Piles
ASTM A252 is the standard specification for nominal-wall cylindrical steel pipe piles, where the cylinder acts as a permanent load-bearing member or shell to form a cast-in-place concrete pile. Welding mainly provides ASTM A252 submerged arc welded steel pipe piles for agricultural, construction and load bearing geotechnical applications. The ASTM A252 specification has three grades: Grade 1, Grade 2, and Grade 3, of which Grade 2 and Grade 3 are commonly used materials.
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.
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.
Seamless steel pipe for general structure (GB/T8162-2008) is a seamless steel pipe for general structure and mechanical structure.
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 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
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.
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.
