This is a great Chinese steel pipe manufacturer with excellent quality and very affordable price. It's worth recommending. In particular, square rectangular steel pipes have a complete range of models. There are many regular stock of steel pipes, and there are factories directly. Recommend it to the engineering, inventory and project providers for consultation.

Description

high-frequency welded pipes

Overview of high-frequency welded pipes(HFW Pipe)

High frequency straight seam Electric resistance welding steel pipe is a product that hot rolled coil is formed by forming machine, uses the Skin effect and proximity effect of high frequency current to heat and melt the edge of tube blank, and carries out pressure welding under the action of extrusion roller to realize production.

Advantage of high frequency resistance welded steel pipe

Excellent mechanical strength

High-frequency resistance welded steel pipe is different from ordinary welded steel pipe in the welding process. The weld is made by melting the base material of the steel strip body, and its mechanical strength is better than that of ordinary welded pipes.

Appearance is smooth and clean

The appearance is smooth and clean, with high accuracy, low cost, and small weld reinforcement, which is conducive to the coating of 3PE anti-corrosion coating.

Classification of high frequency resistance welded steel pipes(HFW Pipe)

High frequency welded steel pipes are mainly divided into four categories, namely: 
1. Welded steel pipes for low-pressure fluid transportation; 
2. Galvanized welded steel pipes for low-pressure fluid transportation; 
3. Ordinary carbon steel wire sleeves; 
4. Straight seam welded steel pipe
1. Welded steel pipes for low-pressure fluid transportation (GB/T3092-1993), also known as general welded pipes or black pipes. It is a welded steel pipe used for conveying water, gas, air, oil, heating steam and other general low pressure fluids and other purposes. The wall thickness of steel pipes can be divided into ordinary steel pipes and thickened steel pipes; The forms of connecting pipe ends are divided into non threaded steel pipes (plain pipes) and threaded steel pipes. The specification of steel pipes is represented by the nominal diameter (mm), which is an approximate value of the inner diameter. Traditionally, inches are commonly used, such as 11/2. Welded steel pipes for low-pressure fluid transportation are not only directly used for fluid transportation, but also extensively used as raw pipes for galvanized welded steel pipes for low-pressure fluid transportation.

2. Galvanized welded steel pipes (GB/T3091-1993) for low-pressure fluid transportation, also known as galvanized welded steel pipes, commonly known as white pipes. It is a Hot-dip galvanization welded (furnace welding or electric welding) steel pipe used for conveying water, gas, air oil, heating steam, warm water and other general low pressure fluids or other purposes. The wall thickness of steel pipes can be divided into ordinary galvanized steel pipes and thickened galvanized steel pipes; The forms of connecting pipe ends are divided into unthreaded galvanized steel pipes and threaded galvanized steel pipes. The specification of steel pipes is represented by the nominal diameter (mm), which is an approximate value of the inner diameter. Traditionally, inches are commonly used, such as 11/2.

3. Ordinary carbon steel wire sleeves (GB3640-88) are steel pipes used to protect wires in electrical installation projects such as industrial and civil buildings, installation machinery and equipment.

4. Straight seam electric welded steel pipe (YB242-63) is a steel pipe with a weld seam parallel to the longitudinal direction of the steel pipe. Usually divided into metric welded steel pipes, welded thin-walled pipes, transformer cooling oil pipes, and so on.
