Top S690QL1 steel tube manufacturer in China

The rolling pipe is made by steel plate with welding process. The rolling pipe is mainly used for conveying water, gas, air, oil and hot water or steam, etc. The rolling pipe has the following characteristics. First, it is easy to process. Welding can be done directly on the basis of steel plates, S690QL1 steel tube. Second, the diameter is large, and various large-diameter rolling pipes can be directly customized and processed. Third, the processing speed is fast, saving processing time. Fourth, a small amount of customization can be used for trial proofing to avoid excessive waste.

The company now has S690QL1 steel tube oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than S690QL1 steel tube 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

In order to improve the S690QL1 steel tube corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main S690QL1 steel tube coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking S690QL1 steel tube sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.

Alloy steel means that alloy elements are specially added to improve the properties of steel. For example, nickel can improve the strength without reducing the toughness of steel; chromium can improve the hardness, corrosion resistance and wear resistance of high carbon steel. The properties of S690QL1 steel tube, alloy steel depend not only on chemical composition, but also on proper heat treatment to a greater extent.
