ASTM A36 H beam is a common wide flange beam used in construction and machinery for its medium strength. Low carbon S690QL cev content makes it easy to be welded, machined as well as formed. Therefore, it is often employed by light applications where strength need is not so important.

Steel pipe S690QL cev manufacturing, environmental protection equipment and other manufacturers supply steel products, which have been well received by new and old customers. Steel sales have maintained a strong growth momentum and have achieved a good reputation in the steel industry. The S690QL cev company has a young, energetic and service spirit, high-quality management team.

After extrusion, the S690QL cev tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.
