Q195 galvanized pipe is a surface galvanized sheet with yield strength of 195MPa. Hot-dip galvanized steel pipes are widely used in the manufacturing industries of construction, machinery, coal mining, chemical industry, electric power, railway vehicles
DC01 Galvanized steel pipe is used for automobiles, sanitary ware, food machinery, pressure vessels, nuclear power, chemical equipment, elevators, rail transit, machinery manufacturing, structural piping, and architectural decoration.
DX52D galvanized pipe is manufactured from DX52D grade steel strip, which offers good formability. After forming and welding into a pipe, it is hot-dip galvanized for corrosion protection.
Scope of Application:
Construction: Scaffolding, handrails, protective fencing, and support structures for greenhouses.
Plumbing: Low-pressure water and gas distribution lines in residential and commercial buildings.
Electrical: Conduit for cable protection.
General Engineering: Non-critical structural members and frames.
G550 Galvanized Steel Pipe refers to high-strength structural pipes manufactured from G550 grade galvanized steel coils or sheets through forming and welding processes, followed by hot-dip galvanizing. The "G550" designation indicates the base material's minimum yield strength of 550 MPa, making it part of the ultra-high-strength galvanized steel series. This product combines exceptional mechanical properties with superior corrosion resistance, suitable for heavy-duty structural and engineering applications.
DX51D Galvanized steel pipe has low melting point, good fluidity, easy plastic processing and welding, and is resistant to atmospheric corrosion.
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.
304 stainless steel is a kind of universal stainless steel material, rust resistance than 200 series of stainless steel material is stronger. High temperature resistance is also better, can be as high as 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it is concluded in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of less than or equal to 65% of the boiling temperature. It also has good corrosion resistance to alkali solution and most organic and inorganic acids.
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.
