Production process of welded steel pipe

Production process of welded steel pipe

The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of oil in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry, and The drilling, production and transportation of oil and natural gas have effectively promoted the development of variety, output and quality of the steel pipe industry.
Brief Introduction of Polyurethane Direct Buried Insulation Pipe

Brief Introduction of Polyurethane Direct Buried Insulation Pipe

Polyurethane direct buried insulation pipe is a kind of direct buried prefabricated insulation pipe with good insulation performance, safety and reliability, and low engineering cost. Directly buried insulation pipe not only has advanced technology and practical performance that traditional trenches and overhead laying pipelines are incomparable, but also has significant social and economic benefits. It is also a powerful measure for heating and energy saving. The prefabricated direct buried insulation pipe adopts direct buried heating pipeline technology, which indicates that the development of China's heating pipeline technology has entered a new starting point. With the declining world energy and increasing demand, energy conservation, emission reduction, and environmental protection have become global development trends. National and local governments have also vigorously advocated the development, application, and industrialization of energy conservation, emission reduction, and environmental protection products.
The use of 3PE polyethylene anticorrosive insulation pipe

The use of 3PE polyethylene anticorrosive insulation pipe

At present, pipeline anti-corrosion technology has been widely praised in the actual application in the market. Pipeline anti-corrosion technology has been used in industrial equipment such as construction, petroleum, power, metallurgy, national defense, transportation storage, boilers, heat exchangers, fans, vehicles and ships. Among them, the anti-corrosion insulation pipe technology is usually to add anti-corrosion coating on the outer wall of the spiral pipe to reduce corrosion and achieve extended life. At present, the main external anti-corrosion coatings for spiral pipeline anti-corrosion are three-layer PE polyethylene, epoxy resin powder, epoxy coal pitch and so on. It can produce epoxy powder anticorrosive insulation pipe, epoxy coal asphalt anticorrosion steel pipe, etc.
Recognize the role of insulated steel pipes

Recognize the role of insulated steel pipes

The production process of steel jacket steel steam insulation steel pipe is very high-end. After casting, the whole shape is not only able to have better integrity, but also has a beautiful effect. It can be used in various environments and can be adapted to various specifications and models. Match, so whether it is industrial production or living, it is still in ordinary family life.
