The wall thickness can be called a thick-walled steel pipe. There are some doubts about this. It depends on the ratio of the outer diameter of the steel pipe to the wall thickness of the steel pipe. For...
In our daily life, many water pipes are used. Spiral steel pipe is one of them. What should we do if the spiral steel pipe is blocked when we use it? When the pipe is blocked, it will not only affect...
1. Impact test Cut a sample with a length of about 100mm from any position of the coated steel pipe, and conduct an impact test in an environment with a temperature of (20+5) °C to observe the damage...
1). It shall be implemented by "Technical Regulations for Construction Water Supply Plastic Coated Composite Pipeline Engineering" CECS125:2001. 2) The following construction equipment should...
The performance and functions of the original color straight seam steel pipe in the specific use process fully demonstrate the operational contribution and the use performance. After painting and spraying...
First of all, we need to store the spiral steel pipe in the warehouse, not store it in the open, and we need to ensure that the storage in the warehouse is clean. Neat and tidy with good drainage. If...
Coating anticorrosion is a uniform and dense coating formed on the surface of de-rusting steel pipes, which can isolate it from various corrosive media. Steel pipe anti-corrosion coatings are increasingly...
Carbon steel tubes are made of steel ingots or solid round steel through perforation into capillary tubes, and then made by hot rolling, cold rolling or cold drawing. Carbon steel tube plays an important...
Seamless pipes are made from tube blanks of various specifications through high-temperature extrusion, cooling, annealing, finishing and other processes. It is one of the four major construction steel...
The difference and application scenarios of carbon steel pipe and iron pipe: 1) The difference between carbon steel pipe and iron pipe There are differences between carbon steel pipes and ordinary iron...
There are many ways to connect seamless tubes, the most common are the following: 1. Butt welding connection Butt welding connection is one of the most commonly used seamless tube connection methods at...
After hot-rolled seamless steel tubes, the grain refinement of steel, the ingot destroy the cast structure, eliminate defects and microstructure of the resulting dense PIPE, improved mechanical properties....
