The characteristics of fire protection plastic-coated steel pipe, the difference between galvanized steel pipe and plastic-coated steel pipe
First, the characteristics of fire protection plastic coated steel pipe: 1. Hygienic, non-toxic, no fouling, no growth of microorganisms, and ensure fluid quality. 2. Strong flame retardant ability. Under the combustion test, the coating has no spontaneous combustion and does not fall off. 3. The...Read more -
Common Defects and Countermeasures of Anticorrosion and Cathodic Protection of Long-distance Natural Gas Steel Pipelines
1. The importance of anticorrosion of long-distance natural gas steel pipelines At this stage, both domestic and foreign, the demand for natural gas is gradually increasing, among which natural gas has become an irreplaceable and important energy source. In this case, the demand for natural gas w...Read more -
How to solve the deformation problem of spiral seam submerged arc welded steel pipe
The spiral seam submerged arc welded steel pipe rotates and starts to enter the soft formation. Under the action of the tri-cone, the drill bit first produces elastic shear deformation of the formation, and then it is removed under the pressure of the tri-cone. In the simulated environment, the s...Read more -
Three large diameter spiral steel pipe connection methods
The most common connection method for large-diameter spiral steel pipes is welding, but in some projects, threaded connections, flange connections, socket connections, and groove connections are often used. Welding, flange connection Welding and flange connection is traditional spiral steel pipe ...Read more -
Surface treatment method of anti-corrosion spiral steel pipe
1. The surface of the anti-corrosion spiral steel pipe is cleaned with solvent and emulsion, which can remove the organic matter on the surface of the spiral steel pipe, but it cannot remove the surface rust, oxide scale, welding flux, etc., so cleaning can only be used as an auxiliary means. 2. ...Read more -
