1. Generally, large-diameter thin-walled steel pipes are used for the transportation of general lower-pressure fluids such as water, gas, air, oil, and heating steam.2. Ordinary carbon steel wire casing (GB3640-88) is a steel pipe used to protect wires in electrical installation projects such as ind

Precision stainless steel tubes are very characteristic in model specifications and appearance performance. First of all, the thicker the tube wall of this type of stainless steel tube, the higher its cost performance and practicability, and the thinner the tube wall, the processing cost will be gre

3pe anti-corrosion steel pipe means three-layer anti-corrosion PE steel pipe. 3pe anti-corrosion steel pipeline is widely used nowadays, and it is a kind of steel pipeline with better anti-corrosion performance. What anti-corrosion materials are the structure of the 3pe anti-corrosion steel pipe? Wh

In the process of producing straight seam steel pipes, the temperature must be strictly controlled, to ensure the reliability of welding. If the temperature is too low, it may cause the welding position to fail to reach the temperature required for welding. When most of the metal structure is still

Austenitic stainless steel is softened by solid solution treatment. Generally, the stainless steel tube is heated to about 950-1150°C and kept for some time, so that carbides and various alloying elements are fully and evenly dissolved in austenite, and then quickly quenched and cooled. , carbon and

1. The main feature of ordinary seamless steel pipes is that they have no welded seams and can withstand greater pressure. Products can be very rough as cast or cold drew.2. Cold-drawn precision steel pipe is a product that has appeared in recent years, mainly because the inner hole and outer wall h

1. The use of large-diameter straight seam welded steel pipes can be divided into oil well pipes (casing pipes, oil pipes and drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure Fertil

Routine maintenance is required when thick-walled steel pipes are used:Thick-walled steel pipes are widely used steel varieties. It directly affects the economic benefit and personnel's life. All countries in the world attach great importance to the inspection of thick-walled steel pipes and adopt v

The main technical characteristics of spiral steel pipe:During the forming process of the spiral steel pipe, the steel plate is uniformly deformed, the residual stress is small, and there is no scratch on the surface. The processed spiral steel pipe has greater flexibility in the range of diameter a

What they have in common is that they all belong to inner and outer plastic-coated steel pipes, but fire-fighting plastic-coated steel pipes are only one category of inner and outer plastic-coated steel pipes.We are already familiar with the plastic-coated composite steel pipe inside and outside. Wi
