A106 Grade B Steel Pipe

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.

AISI 4130 Alloy Steel Pipe

4130 grade AISI pipe is a low-alloy grade designed with chromium and molybdenum content. The AISI 4130 Pipe is generally referred to as the A335 material, and they exhibit reasonable strength and toughness. The versatile 4130 Chromoly Pipe showcases good corrosion and oxidation resistance in a stress-induced setup. These pipes work well against pitting and reducing acids in marine and harsh environments. They possess a melting point of 1432 degrees C with a density of 7.85 g/cm3.

4140 Alloy Steel Pipe

Grade AISI 4140 is a low alloy steel that contains additions of chromium, molybdenum, and manganese in their alloy. In comparison to Grade 4130, the content of carbon in 4140 is slightly higher. This versatile alloy makes for an AISI 4140 Pipe with good properties. For instance, they have good resistance to atmospheric corrosion along with reasonable strength.

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.
