welded steel pipe

Product Introduction

Welded pipe is an electric welded round pipe that is an alternative to steel pipes.It is a structural grade tube that is suitable for a wide variety of applications where dimensional accuracy and precision tolerances is not a primary concern.A raised weld seam is present inside the pipe.

Spiral welded steel pipe is a kind of practical steel pipe, now it has been widely used in small and medium-sized construction site construction facilities, not only that, spiral steel pipe is often used in mining, power, construction and various pipeline systems, one of the important industries.

On the basis of the original is trying to research this more excellent quality of new spiral steel pipe, the purpose is to spiral steel pipe for everybody to create greater profits for pressure fluid transmission with spiral seam submerged arc welding steel pipe.Spiral welded pipe industry investment risk and prospect consulting analysis report released by China industry research network shows that spiral welded pipe is widely used in the fields of tap water engineering, petrochemical industry, hydropower station, power industry, agricultural irrigation and rural construction.Spiral steel pipe is widely used in agriculture, chemical industry, construction, water conservancy, petrochemical industry.

Key Specifications/ Special Features:

1)Spiral welded pipe is the low carbon carbon structural steel and low alloy steel strip according to certain Angle of helix Angle (called molding) rolled into a tube billet, then pipe seam welding made up, it can use a narrow strip in the production of large diameter steel pipe.* wall thickness, according to its specifications with diameter welded pipe shall ensure that the water pressure test, the tensile strength and cold bending properties of the weld in accordance with regulations.

2)Commonly used standards of the spiral steel pipe can be divided into: SY/T5037-2000 (solid, also known as the common fluid conveying pipe with spiral seam submerged arc welding steel pipe), GB/T9711.1-1997 (national standard, also known as oil and gas industry conveying pipe delivery technical conditions in the first part: grade A steel pipe (GB/T9711.2 strict grade B steel pipe)), API 5 l (American petroleum institute, also known as the pipeline steel pipe; which can be divided into PSL1 and PSL2 two levels), SY/T5040-92 (pile with spiral seam submerged arc welding steel pipe).

Product Specification

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.
