Production process of welded steel pipe

During production process of welded steel pipe, the most common parts that we can see are diverse such as tubular type or square type. Some parts even exist in the form of flake and each part has its own value. In the production and processing, welded steel pipe is widely used and it is the common material for building. Do you know how to form welded steel pipe? Actually, its material is cold rolled steel plate as well as a steel strip. They can be directly used in processing equipment. The production process is not very complex. You should learn some basic information about welded steel pipe.

A kind of fluid pipe with low pressure is also a type of individual of welded steel pipe which is mainly testing process for water and gas. After completing the welding procedure, its procedure is more than general welding pipe and steel pipe price will be higher than that of general welding pipe. As you know, the specification of welded steel pipe in steel pipe market is very strict. So there are lots of pipes which are not fit with the market standard. Therefore, the producers generally have a unified specification for production, which can gain a good reputation from customers.

For square steel pipe which is also a kind of welded steel pipe, its production process is relatively complex compared with round steel pipe. At first, ultrasonic examination of board is needing when the plate is not within the distance of production line so that w can ensure the safety. After that, milling is also important around the steel plate in production process, which can make the range suitable. Finishing this procedure, bending is another step for processing welded steel pipe to make certain curvature. At last, tubular shape will be formed step by step with sophisticated equipment.

After a serious of welding and ultrasonic testing as well as pressure testing, the steel pipe should be coated with corrosion resistant material to ensure that the round steel pipe is not affected by any external intrusion of corrosion substances during use. So the finished ERW occupies a very important position in the field of welding. After understanding of production process, you will be more reasonable when purchasing steel pipes. Steel pipe price is not the crucial factor compared with steel pipe quality. If you want to know more about welded steel pipe, contact us please.
