Anti-corrosion Countermeasures for Oil Casing
1. First of all, do a good job of water quality standards, and strictly monitor and manage water quality. Implement cleaning and separate injection, strengthen the cleaning of the main water pipeline, ensure that the water quality in the station and the bottom of the well meet...Read more -
Welding treatment of thick-walled spiral steel pipe
Thick-walled spiral steel pipe is a method of arc welding under the flux layer, which is formed by using the heat generated by the arc burning between the flux and the welding wire under the flux layer, the base metal, and the melting wire flux. In the process of use, the prin...Read more -
Hardness index of anti-corrosion spiral steel pipe
The ability of metal materials to resist the indentation of the surface of hard objects is called hardness according to different test methods and application ranges. The hardness can be divided into Vickers hardness, Shore hardness, Brinell hardness, Rockwell hardness, microh...Read more -
What are the factors that affect the performance of the steel pipeline
Factors that degrade pipe materials or affect their function include pH, soil and water resistivity, abrasion resistance, chloride, sulfate or acid corrosion, fire resistance, crack propagation and oxidation of thermoplastics and electrochemistry of steel corrosion. The above ...Read more -
Safety protection in the construction of anti-corrosion steel pipe
At present, the more commonly used steel pipes are anti-corrosion steel pipes. There are mainly 3PE anti-corrosion steel pipes, TEPE anti-corrosion steel pipes, epoxy resin anti-corrosion steel pipes, etc. So, what should be paid attention to during the construction of anti-co...Read more -
Connection method of the natural gas three-way valve
1. The two outlet pipes with valves are connected to gas-consuming devices (such as gas stoves, barbecue stoves, water heaters, heaters, etc.). The rest is the inlet of the intake pipe, which should be connected to the inlet pipe of the pipeline gas meter or the pressure-reduc...Read more -
Welding technology method of spiral welded pipe
The inner and outer surfaces of the large-diameter welded pipe of the spiral seam submerged arc welded pipe should be bright, and there should be no residual acid and oxide scale. Surface defects should be removed by grinding, the grinding place should have a smooth transition...Read more -
Why You Should Replace Your Galvanized Pipes
You Should take a closer look at your water and sewer system. Many homes that were built up to 20-30 years back may have galvanized pipes, which are now known to be vulnerable to corrosion and are potentially hazardous. What Are Galvanized Pipes? Galvanized pipes are iron pipe...Read more -
Operation and Application of Butt Welding
Butt resistance welding (hereinafter referred to as butt welding) is a kind of resistance welding method that uses resistance heat to weld two workpiece together along the whole end face at the same time. Elbow, butt welding flange and other stainless steel pipe fittings are m...Read more
