Stainless steel pipe sandblasting is the process of cleaning and roughening the substrate surface through the impact of high-speed sand flow. Powered by compressed air, a high-speed spray beam is formed and the spraying material (copper ore, quartz sand, silicon carbide, iron sand, Hainan sand) is sprayed at high speed onto the surface of the […]
Steel pipe and human life, production activities are inseparable, steel pipe production in the steel industry occupies an irreplaceable position. From people’s daily utensils, furniture, water supply and drainage, gas supply, ventilation and heating facilities to the manufacture of various agricultural appliances, the development of underground resources, national defense and aerospace guns, bullets, missiles, rockets, […]
3PE coated steel pipe substrate material includes a spiral pipe, seamless and straight pipe joints. 3PE anti-corrosion seamless steel pipe substrate and molten plating liquid occurs in a complex physical and chemical reaction, the formation of a tightly structured zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel […]
1, along the spiral tube in different directions to take samples for tensile testing and impact testing, found that the yield limit and strength limit of the test in different directions is very small difference, generally only in the range of 5-10%, while the cvn value of different directions of specimens vary greatly, cvn value […]
Because of the large mass of spiral welded pipes, they must be stacked outdoors, but it is difficult to avoid being exposed to the sun and rain, so the problem of rust has been plaguing the storage time and conditions of spiral welded pipes. Therefore, it is necessary to provide a comprehensive answer to the […]
If oil is attached to the surface of the workpiece during heating, the thickness and composition of the oxide skin on the oil-attached part is different from that of the other parts, and carburization will occur. The part of the base metal under the oxide skin that is carburized will be seriously eroded by acid. […]
Spiral steel pipe in the factory should be done before the mechanical properties of the test and flattening test and flaring test, and to reach the requirements of the specification rules. Spiral steel pipe quality inspection methods: from the appearance of the judgment, that is, in the appearance of the inspection. Appearance inspection of welded […]
Solvent-free epoxy coatings with low viscosity curing agent, cured coating has outstanding anti-corrosion function, hardness resistance and denseness. And there is a relatively suitable use period and curing time. In addition to the insulating property and excellent chemical stability of solvent-free epoxy coating, the coating has made great progress in adhesion, resistance, impact strength and […]
Anti-corrosion steel pipe is a commonly used carrier for oil and gas transmission, one of the important facilities of ground engineering. It is a steel pipeline that can effectively prevent or slow down the corrosion phenomenon by chemical or electrochemical reaction during transportation and use after processing by anti-corrosion process. Anti-corrosion pipeline is the link […]
Now the process of domestic spiral steel pipe are double-sided submerged arc welding, double-sided submerged arc welding skills were created and used in 1940, its welding process and hand welding has the same local, is the use of slag welding, spiral steel pipe submerged arc welding and hand welding is different from the local wire […]
