There are two main differences between oil casing and oil drill pipe: 1. Different uses; 2. Different materials.Oil casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well after the drilling process and completion. Each well uses se

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

After a series of treatments such as forming, welding, and cooling, the spiral steel pipe still needs to be sawed. In this link, the length of the technical spare ruler directly affects the quality and sales of the finished welded pipe, so the length of the spare ruler should be controlled between (

Nowadays 3PE coated steel pipe is the most popular steel pipe in the market. Three-layer polyethylene(3PE） is one of the main external anticorrosion technology systems for buried pipelines. It's environment-friendly, anti-corrosion performance high, operates quickly, and saves more time during the p

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

Steel elbow: the most commonly used is the seamless steel elbow, which is divided into a long-radius elbow and a short-radius elbow. Among them, the long-radius elbow is the most commonly used, and its application is also very extensive.Steel elbows are distinguished according to specifications: sma

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

The high-frequency welding process of straight seam steel pipe is completed in the high-frequency welded pipe unit. The high-frequency welded pipe unit is usually composed of rolling forming, high-frequency welding, extrusion, cooling, sizing, flying saw cutting, and other components. The front end

316 stainless steel pipe with the standard export package to ensure the steel pipe obeys the transportation requirement. These stainless steel pipes are seamless steel pipes for industrial fluid transport. It's with several quality control steps to ensure the steel pipes' quality. For such fluid tra

1. It completely solves the problem of mutual friction between the closed surfaces of traditional connecting steel pipes and affects the sealing; the flow resistance is small, and the resistance coefficient of the stainless steel tee is equal to that of the steel pipe section of the same length;2. T
