Product Description

Product Description: Galvanized steel pipe, also known as galvanized steel pipe, hot dip galvanizing is the process of reacting molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and coating. Hot dip galvanizing involves first pickling the steel pipe to remove iron oxide from the surface of the steel pipe. After pickling, the steel pipe is cleaned by chlorination or zinc chloride aqueous solution or a mixture of chlorination and zinc chloride aqueous solution, and then sent to the hot dip galvanizing tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. Most of the processes in the north adopt the zinc plating strip direct coil zinc replenishment process.

product details

technical requirement

1. Brand and chemical composition The grade and chemical composition of steel used for galvanized steel pipes should comply with the grade and chemical composition of black pipe steel specified in GB/T3091

2. Manufacturing methods The manufacturing method of the black tube (furnace welding or electric welding) is chosen by the manufacturer. Galvanizing adopts the hot-dip galvanizing method.

3. Thread and pipe joint (a) For galvanized steel pipes delivered with threads, the threads should be turned after galvanizing. The thread should comply with the provisions of YB 822. (b) Steel pipe joints should comply with the provisions of YB 238; Malleable cast iron pipe joints shall comply with the provisions of YB 230.

4. The mechanical properties of steel pipes before galvanizing should comply with the provisions of GB 3091. 5. The uniformity of the galvanized layer should be tested on galvanized steel pipes. The steel pipe sample shall not turn red (copper plated) after continuous immersion in copper sulfate solution for

5 times.

6. Galvanized steel pipes with a nominal diameter of no more than 50mm shall undergo a cold bending test. The bending angle is 90 °, and the bending radius is 8 times the outer diameter. During the test, there should be no filler, and the weld seam of the sample should be placed on the outer or upper side of the bending direction. After the test, there should be no cracks or zinc layer peeling on the sample.

7. The hydraulic test should be conducted on a black tube, or eddy current testing can be used instead of the hydraulic test. The test pressure or eddy current flaw detection comparison sample size should comply with the provisions of GB 3092. The mechanical properties of steel are important indicators to ensure the ultimate performance (mechanical properties) of steel,

Specification

performance impact
carbon	The higher the carbon content, the higher the hardness of the steel, but its plasticity and toughness are poorer	180	ASTM D 1709
sulfur	It is a harmful impurity in steel. Steel with high sulfur content is prone to brittle cracking during pressure processing at high temperatures, commonly referred to as thermal brittleness	60	ASTM D 1922
phosphorus	It can significantly reduce the plasticity and toughness of steel, especially at low temperatures, which is called cold brittleness. In high-quality steel, sulfur and phosphorus should be strictly controlled. However, from another perspective, low carbon steel contains high levels of sulfur and phosphorus, which can make it easy to cut and improve the machinability of steel	12	ASTM D 1922
