ASTM 106 Grb 1020 St45 C45 A335 A53 325mm Od Hot Rolled Smls Seamless Carbon Steel Tube Pipe

Product Introduction

Carbon Seamless Steel Pipe / tubes
Seamless steel pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow - liquids and gases (fluids), slurries, powders and masses of small solids.
Hot rolled seamless steel pipe deformation process can be summarized as three stages: extension, perforation and finishing. Hot rolled seamless steel pipes is relative to the cold-rolled, cold rolling is below the recrystallization temperature of the rolling and hot rolled is carried out at above the recrystallization temperature of the rolling. Hot rolled seamless steel pipe can damage the refinement of the crystal grains of the steel, cast microstructure of the steel ingot and eliminate the defects of the microstructure so that the the steel organization compacting, improves the mechanical properties. This improvement is reflected in the rolling direction so that the steel is no longer at a certain extent isotropic; pouring the formation of bubbles, cracks and osteoporosis, under high pressure and temperature can also be welded together.
Hot Rolled Steel Pipes (Seamless Tube) in different size, specifications, grades & thickness as per the client's requirements. The range offered by tubes is available as per the international & national standard and can be available from us at affordable prices. These pipes are used in various application industry like shipbuilding, power plants, oil and gas, automotive, sugar mills and distilleries, cement and construction industries etc.

ASTM A53 Carbon Steel Pipe & Tube
ASTM A53 (ASME SA53) carbon steel pipe is a specification that covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8″ to NPS 26.  A 53 is intended for pressure and mechanical applications and is also acceptable for ordinary uses in steam, water, gas, and air lines.
A53 pipe comes in three types (F, E, S) and two grades (A, B).
A53 Type F is manufactured with a furnace butt weld or may have a continuous weld (Grade A only)
A53 Type E has an electric resistance weld (Grades A and B)
A53 Type S is a seamless pipe and found in Grades A and B)
A53 Grade B Seamless is our most polar product under this specification and A53 pipe is commonly dual certified to A106 B Seamless pipe.
