What Is Steel Pipe?

Steel Pipe is a hollow cylindrical steel profile manufactured through hot rolling, cold drawing, welding, sizing and surface treatment processes. Each qualified Steel Pipe has uniform Steel Pipe outer diameter, consistent Steel Pipe wall thickness, smooth Steel Pipe inner and outer surface, and dense internal metallographic structure of Steel Pipe. Premium Steel Pipe has no Steel Pipe surface cracks, no Steel Pipe pits, no Steel Pipe deformation and no internal porosity defects. Steel Pipe possesses strong Steel Pipe pressure bearing capacity, excellent Steel Pipe bending performance and stable Steel Pipe mechanical toughness. Steel Pipe can be cut, welded, threaded and flanged freely for secondary processing, bringing high flexibility for engineering installation and industrial production. According to different production technologies and usage environments, Steel Pipe includes Seamless Steel Pipe, Welded Steel Pipe, Carbon Steel Pipe, Galvanized Steel Pipe and Alloy Steel Pipe, fully covering all low-pressure, high-pressure, structural and fluid transportation demands of Steel Pipe.

Main Types of Industrial Steel Pipe and Core Features of Each Steel Pipe

The global Steel Pipe market contains complete series Steel Pipe products, and each type of Steel Pipe is professionally manufactured for specific industrial and construction requirements.

1. Seamless Steel Pipe

Seamless Steel Pipe is high-performance integral Steel Pipe produced by piercing and rolling solid steel billet without any welding seam. Seamless Steel Pipe features ultra-compact internal structure, uniform wall thickness and excellent high-pressure resistance. Seamless Steel Pipe can withstand extreme pressure and high-temperature working conditions that ordinary Steel Pipe cannot bear. Seamless Steel Pipe has outstanding mechanical stability and long service life, widely used in petroleum transmission, boiler piping, hydraulic engineering and high-pressure industrial pipeline systems. Seamless Steel Pipe is the preferred high-standard Steel Pipe for heavy industrial engineering.

2. Welded Steel Pipe

Welded Steel Pipe is economical mainstream Steel Pipe formed by steel plate rolling and automatic welding. Welded Steel Pipe has stable structural uniformity, smooth surface and excellent processing adaptability. Welded Steel Pipe features low manufacturing cost and sufficient production capacity, making Welded Steel Pipe the most popular bulk procurement Steel Pipe for low-pressure fluid delivery, building structural support and municipal pipeline projects. Welded Steel Pipe covers most conventional civil and industrial Steel Pipe usage scenarios.

3. Carbon Steel Pipe

Carbon Steel Pipe is universal standard structural and fluid Steel Pipe made of carbon steel material. Common grades Q235B Carbon Steel Pipe, 20# Carbon Steel Pipe and SS400 Carbon Steel Pipe own balanced weldability, stable ductility and reliable tensile strength. Carbon Steel Pipe is easy to process, install and construct, fully meeting general pipeline transportation and structural steel frame demands. Carbon Steel Pipe occupies the largest market share in global Steel Pipe trading.

4. Galvanized Steel Pipe

Galvanized Steel Pipe is anti-corrosion upgraded Steel Pipe with hot-dip galvanized coating. The compact zinc layer fully covers the inner and outer surface of Galvanized Steel Pipe, effectively isolating air oxidation, moisture and salt fog erosion. Galvanized Steel Pipe completely solves the rusting problem of ordinary Carbon Steel Pipe in outdoor and humid environments. Galvanized Steel Pipe is widely applied in water supply pipelines, fire protection piping, fence structures and municipal outdoor Steel Pipe engineering.

5. Alloy Steel Pipe

Alloy Steel Pipe is high-strength high-temperature resistant Steel Pipe with alloy element optimization. Alloy Steel Pipe has higher temperature resistance, stronger pressure resistance and better wear resistance than ordinary Carbon Steel Pipe. Alloy Steel Pipe maintains stable performance under high-temperature and high-pressure extreme conditions, dedicated to power plant piping, chemical industrial pipelines and special high-standard industrial Steel Pipe systems.
