| Product Introduction | |||||||||||||||
| Welded steel pipe, also known as welded pipe, is a steel pipe made by welding steel plates or strips after being rolled and formed, usually with a fixed length of 6 meters. The production process of welded steel pipes is simple, with high production efficiency, multiple varieties and specifications, and less equipment investment, but generally lower strength than seamless steel pipes. | |||||||||||||||
| Overview of welded pipes | Smaller diameter welded pipes use straight seam welding, while larger diameter welded pipes mostly use spiral welding; According to the shape of the steel pipe end, it is divided into circular welded pipes and special-shaped (square, rectangular, etc.) welded pipes; According to different materials and purposes, it is divided into welded steel pipes for mining fluid transportation, galvanized welded steel pipes for low-pressure fluid transportation, and electric welded steel pipes for belt conveyor idlers. According to the specifications and dimensions table in the current national standard, the order is from small to large by outer diameter * wall thickness. | ||||||||||||||
| The purpose of welded pipes | The product is widely used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction, and is one of the twenty key products developed in China. Used for liquid transportation: water supply and drainage. Used for gas transportation: gas, steam, liquefied petroleum gas. Used as a structure: as a pile driving pipe, as a bridge; Pipelines for docks, roads, building structures, etc. | ||||||||||||||
| Characteristics of welded pipes | The production process of straight seam welded pipe is simple, with high production efficiency, low cost, and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Narrow billets can be used to produce larger diameter welded pipes, and billets of the same width can also be used to produce welded pipes of different diameters. However, compared to straight seam pipes of the same length, the weld length increases by 30-100% and the production speed is lower. | ||||||||||||||
| Classification of welding methods | According to different welding methods, it can be divided into arc welded pipe, high-frequency or low-frequency resistance welded pipe, gas welded pipe, furnace welded pipe, Bundy pipe, etc. Welded steel pipe: used in petroleum drilling and mechanical manufacturing industries. Furnace welded pipes: can be used as water and gas pipes, and large-diameter straight seam welded pipes are used for high-pressure oil and gas transportation, etc; Spiral welded pipes are used for oil and gas transportation, pipe piles, bridge piers, etc. Classification by Weld Shape It can be divided into straight seam welded pipes and spiral welded pipes Straight welded pipe The production process is simple, with high production efficiency, low cost, and rapid development. Spiral welded pipe The strength is generally higher than that of straight seam welded pipes, and larger diameter welded pipes can be produced using narrower billets. Welded pipes with different diameters can also be produced using billets of the same width. However, compared to straight seam pipes of the same length, the weld length increases by 30-100% and the production speed is lower. Therefore, smaller diameter welded pipes mostly use straight seam welding, while larger diameter welded pipes mostly use spiral welding. Spiral seam welded steel pipes are divided into two types: automatic submerged arc welded steel pipes and high-frequency welded steel pipes. | ||||||||||||||
