How is stainless steel welded pipe produced

In the 19th century, rolling technology was the only technology used to produce stainless steel and industrial tubes. The process steps involved in this rolling technique are long. It is with the help of funnel rolls that the rolled sheets are made into circular cross-sections and these rolled strips are then welded in a welding process

Fortunately, with development and new technologies, various processes for manufacturing stainless steel tubes and pipes have been formed  Stainless steel tubes and tubes are now manufactured by continuous tube mills using tungsten inert gas. No filler metal or forge welding process is used in this technique.

Stainless steel pipe production process
1. Stainless steel belt. The quality of the stainless steel pipe is the most direct factor than the stainless steel strip. There are many kinds of materials for the stainless steel strip, among which 201, 304, 316 and other materials are common. First, the stainless steel strips go through various quality checks and their edges are trimmed. They are then delivered to the pipe rolling mill by the stainless steel pipe manufacturer to the required size.
2/ Welded pipe equipment. Welded pipe equipment can affect the stability of pipe production. If an enterprise chooses a welded pipe equipment with low stability in order to save costs, it will affect the quality of pipe production. The steel strip is gradually transformed into a tube through a tube rolling mill, and then welded at the edge by argon arc welding plus plasma or high-frequency welding process, thus forming rolled tubes and tubes.
3/ Welded pipe mold. The welded pipe mold is really important. The strain of the stainless steel pipe is often because the welded pipe mold is not in place. The quality of the welded pipe mold affects the brightness of the pipe and the production quality of the pipe.
4/ Polishing equipment. For a bright stainless steel decorative tube, we need to choose a good stainless steel polishing machine, the sturdiness of the polishing machine, and the use of high-quality polishing wax to make the tube brighter.
5/ Other equipment. There are many classifications of stainless steel tubes, such as: square tubes, round tubes, rectangular tubes, special-shaped tubes, etc. The equipment required for the production of pipes of different shapes is also different. In addition to the above mentioned elements,
Washing and heating phase
The stainless steel rolled tubes produced in this way are cut to the required lengths according to the needs of the industry. These stainless steel pipes and tubing are then cleaned to remove dirt. In addition, these rolled tubes and tubes are heat treated to relieve possible stresses during welding and forming. Then heat treatment is carried out on the continuous rolling furnace, which is equipped with a temperature recorder and a controller. After heat treatment, SS pipes and pipes are straightened and pickled to remove surface scale.
Finishing process
These long tubes or stainless steel tubes are then cleaned, heat treated, pickled and straightened. Mark the finished pipe or tubes with a computerized inkjet printer. The tubes will be marked with the material grade trademark, steel stamp, specification label and stamp of third party inspection before being sent to the quality inspection and acceptance department. Proper packaging and warehousing follow this process.
