Product description
ASTM A500 Steel Pipe GI SCH 40 steel tube
Galvanized steel pipe welded joint
Gi pipe Welded Steel Pipe chemical composition.
The steel plate and chemical composition of galvanized steel tube shall conform to the brand and chemical composition of the Steel Pipe used in GB/T3092.
2. Manufacturing method
The manufacturing method of Galvanized Iron Pipe (furnace welding or welding) is selected by the manufacturer. Hot dip galvanizing method is adopted.
3. Thread and pipe joint.
(a) galvanized gas pipe with thread, thread should be made after galvanized. Thread should comply with YB 822.
(b) steel pipe joints shall conform to the provisions of YB 238; The joint of malleable cast iron pipe shall conform to the provisions of YB 230.
4. Mechanical properties of steel tube before galvanization should comply with GB 3092.
5. The uniform Galvanized Steel Pipe shall be tested for the uniformity of galvanized layer. The steel tube samples were impregnated 5 times in the copper sulfate solution without turning red (copper plating).
6. Cold bending test nominal diameter of no more than 50mm galvanized steel pipe shall be subjected to cold bending test. Bending Angle is 90 °, bending radius to diameter 8 times. When the test is not filled with filler, the weld should be placed on the outside or upper part of the bending direction. After the test, there should be no crack and zinc peeling.
7. Water pressure test should be carried out in Galvanized Gas Pipe, and eddy current test should be used instead of water pressure test. Test pressure or eddy current testing should be in accordance with GB 3092. The mechanical property of steel is an important index to ensure the final performance of steel.
