Seamless Steel Pipe mills, volume should go through continuous annealing (CAPL unit) to eliminate cold hardening and rolling stress, or batch annealing reach the ASTM A335 seamless steel pipe mechanical properties of the corresponding standard specifies. Seamless Steel Pipe surface quality, appearance, dimensional accuracy ASTM A335 seamless steel pipe better than hot-rolled plate, and right-rolled thin product thickness is about 0.18mm, so the majority of users favor.

Seamless Steel Pipe deep processing of high value-added products. Such as electro-galvanized, hot dip galvanized, electro-galvanized fingerprint resistant, painted steel roll damping composite steel, ASTM A335 seamless steel pipe laminating steel plates, etc, so that the excellent quality of these products has a beautiful, high resistance to corrosion, has been widely used.
