r b< c=>Welded pipe production process:
c=rr b< c=>Long seam welded pipe production process is simple, with high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Narrow billets can be used to produce welded pipes with larger diameters. Welded pipes with different diameters can also be produced with billets of the same width. However, compared with straight seam pipes of the same length, the weld length is increased by ~%, and the production speed is lower.

r
c=rr b< c=>It is divided into general welded pipe, galvanized welded pipe, oxygen blown welded pipe, wire casing and metric welded pipe , roller pipes, deep well pump pipes, automotive pipes, transformer pipes, welded thin-walled pipes, welded special-shaped pipes, scaffolding pipes and spiral welded pipes.
r
c=rr b< c=>General welded pipe: General welded pipe is used to transport low-pressure fluid. Made of steel. It can also be made of other mild steels that are easily weldable. Steel pipes need to undergo experiments such as hydraulic pressure, bending, and flattening, and have certain requirements for surface quality. The delivery length is usually 10,000 square meters, and it is often required to be delivered in a fixed length (or multiple lengths). The specifications of welded pipes are expressed in nominal diameter (millimeters or inches). The nominal diameter is different from the actual. According to the specified wall thickness, there are two kinds of welded pipes: ordinary steel pipes and thickened steel pipes.
r
c=rr b< c=>Galvanized steel pipe: In order to improve the corrosion resistance of steel pipes, general steel pipes (black pipes) are galvanized. Galvanized steel pipes are divided into two types: hot-dip galvanizing and electric steel zinc. Hot-dip galvanizing has a thick zinc layer and electro-galvanizing has low cost.
r
c=rr b< c=>Oxygen-blown welded pipe: used as a pipe for oxygen-blown steelmaking. It is generally a small-diameter welded steel pipe with eight specifications: / inch. Made of or steel strip. In order to prevent corrosion, some are aluminized.
r
c=rr b< c=>Wire casing: that is, ordinary carbon steel electric welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from. The wire sleeve has a thin wall and is mostly used after being coated or galvanized, requiring a cold bending test.
r
c=rr b< c=>Metric welded pipe: specifications are used as seamless pipes, welded steel pipes expressed in outer diameter * wall thickness in millimeters, made of ordinary carbon steel, high-quality carbon steel It can be made by hot-strip and cold-strip welding of low-alloy steel, or by hot-strip welding and then cold drawing. Metric welded pipes are divided into general-purpose and thin-walled pipes. They are generally used as structural parts, such as transmission shafts, or to transport fluids. Thin-walled pipes are used to produce furniture, lamps, etc. The strength and bending test of the steel pipe must be ensured.
r
c=rr b< c=>Roller tube: used for belt conveyor roller electric welded steel pipe, generally made of B steel and steel, diameter... There are certain requirements for the curvature of the pipe, the end face to be perpendicular to the center line, and the ovality. Generally, water pressure and flattening tests are conducted.
r
c=rr b< c=>Transformer tube: used to make transformer heat pipes and other heat exchangers. It is made of ordinary carbon steel and requires flattening, flaring, bending, and hydraulic pressure. test. Steel pipes are delivered in fixed lengths or multiple lengths, and there are certain requirements for the bending of the steel pipes.
r
c=rr b< c=>Special-shaped pipes: square pipes, rectangular pipes, hat-shaped pipes, and hollow rubber steel pipes for doors and windows welded from ordinary carbon structural steel and equal steel strips. Mainly used as agricultural machinery parts, steel windows and doors, etc.
r
c=rr b< c=>Electrically welded thin-walled tube: mainly used for making furniture, toys, lamps, etc. In recent years, thin-walled tubes made of stainless steel strips have been widely used in high-end furniture, decorations, fences, etc.
r
c=rr b< c=>Spiral welded pipe: a low carbon carbon structural steel or low alloy structural steel strip is rolled into a pipe at a certain spiral angle (called forming angle) It can produce large-diameter steel pipes from narrow strips of steel. Spiral welded pipes are mainly used for oil and natural gas transmission pipelines, and their specifications are expressed by outer diameter * wall thickness. Spiral welded pipes are either single-sided or double-sided. Welded pipes should ensure that the hydraulic pressure test, tensile strength and cold bending performance of the weld meet the regulations.
