Classification Of Steel Tubes

Steel Pipe Can Be Divided Into Two Categories According To The Production Method: Seamless Steel Pipe And Seam Steel Pipe, Seam Steel Pipe Is Referred To As Straight Steel Pipe.

1. Seamless Steel Pipe Can Be Divided Into: Hot Rolled Seamless Pipe, Cold Drawn Pipe, Precision Steel Pipe, Hot Expansion Pipe, Cold Spinning Pipe And Extrusion Pipe, Etc.Seamless Steel Tubes Are Made Of High Quality Carbon Steel Or Alloy Steel, Which Can Be Hot Rolled Or Cold Rolled (Drawn).

2. Welding Steel Pipe Is Divided Into Furnace Welding Pipe, Electric Welding (Resistance Welding) Pipe And Automatic Arc Welding Pipe Because Of Its Different Welding Form Is Divided Into Straight Seam Welding Pipe And Spiral Welding Pipe Two Kinds, Because Of Its End Shape Is Divided Into Circular Welding Pipe And Special-Shaped (Square, Flat, Etc.) Welding Pipe. Steel Pipe According To The Tube Material (I.E. Steel) Can Be Divided Into: Carbon Tube And Alloy Tube, Stainless Steel Tube, Etc.Carbon Pipe Can Be Divided Into Ordinary Carbon Steel Pipe And High Quality Carbon Structure Pipe. Alloy Pipe Can Be Divided Into: Low Alloy Pipe, Alloy Structure Pipe, High Alloy Pipe, High Strength Pipe. Bearing Tube, Heat And Acid Resistant Stainless Tube, Precision Alloy (Such As Cutting Alloy) Tube And High Temperature Alloy Tube, Etc.

According To The Coating Characteristics

Steel Pipe According To The Surface Coating Characteristics Can Be Divided Into: Black Pipe (Not Coated) And Coated Tube.

Coating Tube Has Galvanized Pipe, Aluminum Plating Pipe, Chrome Plating Pipe, Aluminizing Pipe And Other Alloy Layer Of Steel Pipe.

Coating Tube Has Outer Coating Tube, Inner Coating Tube, Inner And Outer Coating Tube. Commonly Used Coatings Are Plastic, Epoxy Resin, Coal Tar Epoxy Resin And A Variety Of Glass Type Anti-Corrosion Coating Materials.

Classification By Use

Steps 1 Pipe For Plumbing. Such As: Water, Gas Pipe, Steam Pipe With Seamless Pipe, Oil Transmission Pipe, Oil And Gas Trunk Pipe. Agricultural Irrigation Water Faucet With Pipe And Sprinkler Irrigation Pipe.

2. Pipes For Thermal Equipment. Such As The General Boiler With Boiling Water Pipe, Superheated Steam Pipe, Locomotive Boiler Heat Pipe, Smoke Pipe, Small Smoke Pipe, Arch Brick Pipe And High Temperature And High Pressure Boiler Tube, Etc..

3. Mechanical Industry Pipe. Such As Aviation Structure Pipe (Round Pipe, Ellipse Pipe, Flat Ellipse Pipe), Automobile Half Shaft Pipe, Axle Pipe, Automobile Tractor Structure Pipe, Tractor Oil Cooler Pipe, Transformer Pipe And Bearing Pipe, Etc.

4. Petroleum Geology Drilling Pipe. Such As: Petroleum Drilling Pipe, Petroleum Tubing, Petroleum Casing And Various Pipe Joints, Geological Drilling Pipe (Casing, Active Drill Pipe, Drilling, Hoop And Pin Joints, Etc.).

5. Chemical Industry Pipe. Such As: Petroleum Cracking Pipe, Chemical Equipment Heat Exchanger And Pipe Pipe, Stainless Acid-Resistant Pipe, Fertilizer With High Pressure Pipe And Transport Chemical Medium Pipe, Etc.

6. Other Departments Use Pipes. Such As: Container Pipe (High-Pressure Gas Cylinder Pipe And General Container Pipe), Instrument Pipe And So On.
