As an efficient special means of transportation, pipeline transportation has played an increasingly important role in the fields of oil and natural gas transportation. At present, domestic large-diameter transportation pipelines are mainly constructed with spiral welded pipes. To ensure the reliable
The butt welding flange is that the pipe diameter and wall thickness of the interface end is the same as the pipes to be welded, and are welded like two pipes. The flat welding flange is a concave table that is slightly larger than the outer diameter of the pipe at the interface, and the pipe is ins
Product name: Seamless carbon steel pipeMaterial: Carbon steelSize: SCH 80x1/2''x5.8MStandard: ASTM A106Quantity: 7000 tonsMany cooperations have given the customer full confidence in THREEWAY STEEL.
1. The reasons for the uneven wall thickness of the spiral shape are: the uneven wall thickness caused by the adjustment reasons such as the uneven rolling centerline of the piercer, the inclination angle of the two rolls, or the reduction amount in front of the plug is too small, generally along th
The bent pipe is produced step by step and then made into a finished product. During the whole production process, because the pipe must be bent, and the bending of the pipe requires some technology, the degree of bending is also different, than in the whole production process What are the technical

Stainless steel elbows are often a product accessory that is often needed in projects. How much do you know about stainless steel elbows? What are the characteristics of stainless steel elbows? Next, let's take a look at the characteristics of stainless steel elbows.1. Stainless steel stamping elbow
1. The material of stainless steel pipe fittings should not be in direct contact with other metals, and should be padded with non-metallic materials such as wooden boards or rubber sheets.2. The arc starting, ending, and arc starting of stainless steel pipe fittings are reflowed, and the arc ending
At present, the welding methods of stainless steel welded pipes used in the industry mainly include argon arc welding, high-frequency welding, plasma welding, and laser welding. Several welding methods have their characteristics. At present, the most used are argon arc welding and high-frequency wel
How does the spiral welded pipe need to be anti-corrosion? This is also a very important part of the application of spiral steel pipes in daily projects. Extending the daily life of the spiral steel pipe is also the most important focus of the customer for the project. The following is the anti-corr
