Welded Pipe. Welded pipe comes in three forms:welded on the outside diameter, welded on the inside diameter or welded on both sides. The commonality is that they all have a seam! Manufacturing and applications:The manufacturing process of welded pipe starts by rolling out a steel coil to the desired thickness to form a flat strip or plate.
High Quality Custom Construction Pipe, Structure Steel The Construction Welded Steel Pipe used in building structure has the characteristics of relatively simple process, which is divided into high frequency welding, submerged arc welding, resistance welding, welding, spiral welding, etc., and has a wide range of applications in civil construction, petrochemical, light industry and other departments.

The welding process is the key process of the construction of the pressure pipe and the main process. The pressure pipeline group, the welding quality is good or bad directly affect the pipeline flow direction of medium flow rate, pipe wear and safe operation, it has very strict requirements for pressure pipe welding quality, in addition to the requirements of the welded joints for full
Pressure pipe welding quality controlThe welding process is the key process of the construction of the pressure pipe and the main process. The pressure pipeline group, the welding quality is good or bad directly affect the pipeline flow direction of medium flow rate, pipe wear and safe operation, it has very strict requirements for pressure pipe welding quality, in addition to the requirements of the welded joints for full
Process Flow and Precautions of High Frequency Welded Pipe 3. The effect of high frequency welding on the quality of steel pipes. In the process of high-frequency welding of steel pipes, the control of the welding process and process parameters, the placement of the induction coil and the impedance device, etc. have a great influence on the welding quality of the steel pipe weld

Lastly, high carbon and low-alloy steel plate can best be welded with the work in the level position. 3. Follow Simple Principles for Joint Geometry and Fitup Joint dimensions are chosen for fast welding speeds and good weld quality. Proper joint geometry is based upon some simple principles:Fitup must be consistent for the entire joint.

Welding steam pipe AWS Welding DigestOct 18, 2019 · Welding of high-pressure steam pipe . Some alloys are prone to cracking during welding, including low- and medium-alloy steels specially developed for their high strength. Metallurgists have learned that heating the joint prior to and after welding can significantly reduce sensitivity to cracking.
Jul 31, 2020 · The high-quality ERW steel pipe not only cannot distinguish the weld, but also the weld coefficient reaches 1, which realizes the match between the weld area and the base metal. At the same time, the ERW steel pipe has the advantages of using hot-rolled coil as the raw material, and the uniform wall thickness can be controlled at about plus or
