The problem of uneven thickness of the anti-corrosion coating of the spiral steel pipe and the treatment method
Spiral steel pipes are mainly used as fluid pipes and piling pipes. After the steel pipes are made, if they are used for running water, they will generally be treated with anti-corrosion on the inner or outer surface. The general anti-corrosion includes 3pe anti-corrosion, epo...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 -
How to clean the dirt in the steel pipe
There are three ways to clean the substances in the steel pipeline. Internal cleaning method of pipeline 1. Chemical cleaning The chemical cleaning pipeline is to use chemical agents to temporarily transform the pipeline. The temporary pipeline and the circulating pump station...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 -
Product advantages of anti-corrosion steel pipe
1. Combine the mechanical strength of steel pipes and the corrosion resistance of plastics; 2. The outer wall coating is more than 2.5mm, resistant to scratches and bumps; 3. The friction coefficient of the inner wall is small, 0.0081-0.091, which reduces energy consumption; 4...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 -
What is the difference between the inner and outer plastic-coated composite pipe and the general galvanized pipe
Water-proof and plastic-coated steel pipes are based on steel pipes and plastic powder (such as epoxy resin) as coating materials. layers of composite pipes. The surface is lubricated, reduces fluid resistance, reduces flow resistance, increases flow, does not scale, and is no...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
