 Product Description

SGCC galvanized pipe is a commercial quality hot dip galvanized steel. Among them, the initial letter "S" stands for steel, "G" stands for galvanized, and "C" stands for cold-rolled steel. That is, the base material is cold rolled steel. The fourth letter "C" stands for commercial quality, which is equivalent to DX51D material according to the EN 10327 standard. SGCC galvanized pipe is made from SGCC galvanized coil.

 Product Application

SGCC Hot-dip galvanized steel pipes are extensively utilized in various industries including construction, machinery, coal mines, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, exploration machinery, and other manufacturing sectors.


SGCC Galvanized steel pipes are welded steel pipes that have a zinc layer applied through a hot-dip or electroplating process on their surface. This galvanization process enhances the corrosion resistance of the steel pipes and prolongs their lifespan. SGCC Galvanized pipes find wide applications in different fields. Apart from being used as pipeline pipes for general low-pressure fluids like water, gas, and oil, they are also employed as oil well pipes and oil pipelines in the petroleum industry, particularly in offshore oil fields. Additionally, they are utilized as oil heaters and condensers in chemical coking equipment, pipes for coolers in coal distillate wash oil exchangers, pipes for trestle pipe piles, and support frames for mine tunnels, among others.

Production Process

 Production Process

1716359984056


  • Forming

  • Welding

  • Heat treatment

  • Size correction

  • Galvanizing Surface treatment

  • Inspection and testing


1. Forming

Steel strip uncoiling: The hot-rolled or cold-rolled steel strip is uncoiled from the coil and straightened by a straightening machine.

Forming process: The straightened steel strip is gradually rolled into a tube shape through a forming machine. The forming machine usually includes several forming rollers, which gradually roll the flat steel strip into a tube blank.


2. Welding

High-frequency welding: Use high-frequency welding equipment to weld the formed steel pipes, and the welds must be uniform and strong.

Welding seam treatment: After welding, the welding seam needs to be trimmed to remove burrs and spatter generated during the welding process.


3. Heat treatment

Annealing treatment: The welded steel pipe is annealed to eliminate welding stress and improve the plasticity and toughness of the pipe.


4. Size correction

Sizing and shaping: Use the sizing machine and shaping machine to correct the size of the welded pipe to ensure that its roundness and diameter meet the standard requirements.


5. Galvanizing Surface treatment

Pretreatment: Clean the surface of the steel pipe to remove impurities such as oxide scale, oil stains, etc. Common methods include acid cleaning, alkali cleaning, etc.

Hot dip galvanizing:Dip plating: Dip the cleaned steel pipe into molten zinc liquid to cover the surface of the steel pipe with a uniform zinc layer.

Cooling: The galvanized steel pipe is cooled, usually through water cooling or air cooling, to solidify the zinc layer.

Passivation treatment: Passivation treatment is performed on the galvanized steel pipe to further enhance its anti-corrosion performance.


6. Inspection and testing

Appearance inspection: Check the uniformity and surface quality of the galvanized layer, and whether there are defects such as missing plating and peeling.

Dimensional measurement: Measure the outer diameter, wall thickness, length, and other dimensions of the steel pipe to ensure compliance with standards.

Performance testing: including tensile test, bending test, impact test, etc. to ensure that the mechanical properties of the steel pipe meet the requirements.

Coating test: Test the thickness and adhesion of the galvanized layer to ensure anti-corrosion performance.
