Advantages and disadvantages of hot-dip galvanized steel pipe  

 Galvanized steel pipe is the strip or plate bending by the spiral bending forming, with double-sided submerged arc automatic welding in the welding seam and seam made of galvanized steel pipe, for the following reason it can be widely used in water, electricity, chemical and other industries in the production of:

 1. as long as the change of forming Angle, you can use the same width of strip steel in the production of various diameter of steel tube, easy to adjust.  

2.Because it is continuous bending forming, the fixed length of the spiral pipe is not limited, and the length can be set at will.  

3.The weld spiral is evenly distributed on the whole circumference of the spiral pipe, so the spiral pipe has high dimensional accuracy and strong strength.  

4. Easy to change the size, suitable for small batch, multiple varieties of spiral pipe production. galvanized iron pipe schedule 40 price - GKSTEELPIPE

 The weld seam of hot-dip galvanized steel pipe is longer than that of straight seam pipe of the same specification, and the pressure of hot-dip galvanized steel pipe is the largest under the same specification wall thickness.  The defect of weld of hot-dip galvanized steel pipe is "oblique defect".  In the process of use, the principal stress direction, that is, the equivalent defect length of the axis direction of the steel pipe is smaller than that of the straight joint pipe;  Secondly, because the pipeline steel is rolled, the impact toughness has a large anisotropy, and the CVN value along the rolling direction is 3 times higher than that perpendicular to the rolling direction. 

Hot dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, mining machinery and other manufacturing industries.  

Application of galvanized steel pipe  

Galvanized steel pipe a welded steel pipe with a hot dip coating or electrogalvanized coating.  Galvanized steel tube can increase the corrosion resistance, prolong the service life.  Galvanized pipe USES is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for tube, and trestle pile, mining tunnel supporting frame tube, etc.
