Plastic coated steel pipe is also more and more commonly used in people's ordinary life, but its use is more stable than ordinary steel pipe, with many advantages. People can not help but ask, what is the coated steel pipe? In short, the plastic coated steel pipe is to spray the plastic on th...

How can we identify the quality defects of stainless steel butt welding elbows, there are many types of forms can be made and processed, the selection of pressing method is difficult to produce this kind of large mold, and the production time is particularly high, so how should we identify the q...

In the modern industrial industry, pipe connectors play a very important role. As a common pipe connection, carbon steel flanges are widely used in various engineering projects. As everyone knows, in view of the emergence of a humid environment, carbon steel flanges are easily affected by rus...

Polyurethane insulation pipe is a popular tubular insulation material in the current market. In view of its excellent thermal insulation performance and good thermal conductivity, it has been widely used in many industries. Compared with other insulation pipes, polyurethane insulation pipes h...

In daily life, we in the application of stainless steel elbow links, generally speaking, only open and full seal, do not allow the overall adjustment of the total flow Not only that, it will avoid the abundant cover, and will continue to accelerate the damage, his sampling will be relatively ...

Obviously, TPEP anti-corrosion steel pipe not only has the strength of steel pipe, but also has the advantages of corrosion resistance, alkali resistance and low resistance of plastic pipe. It is a new type of composite fluid transport pipeline. Improved galvanized pipe defects, such as susce...

In people's lives, there are many places where you can see all kinds of liquid objects such as oil, but it is not clear whether you have carefully thought about how these things are passed on to every place in the country? As we all know, oil is a kind of flammable object, and if it is expose...

All metals react with oxygen in the atmosphere, forming an oxide film on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel inherits and oxidizes, allowing the corrosion to develop and eventually produce holes. The coating of carbon steel can be protected by painting o...

Enhance the corrosion resistance of carbon steel butt welding elbow in the original performance medium, especially the resistance to chloride partial etching, enhance the high temperature performance of austenitic stainless steel tee, and enhance the strength and quenching reliability of carbon ...

In domestic urban central heating, the hot water and steam generated by the heat source are transmitted to each heat user according to the pipeline to form a heating network. The heating pipe is the link that transfers heat from the heat source to the heating system of each user In view of th...

What brand of prefabricated directly buried thermal insulation steel pipe quality is better, not only has the leading process and application performance that can not be compared with that of pipe trenches and laying pipes in the past, but also has obvious social value and economic benefits, and...

This paper briefly introduces the production process of large diameter spiral steel pipe, which must pass rigorous physical and chemical inspection before joining. Wire or double wire submerged arc welding is used for end to end connection of strip steel, and self-submerged arc welding is used t...
