Modern companies choose seamless steel pipes because seamless steel tubes are lighter in raw material, stronger in strength, and more tolerant than those in lsaw steel pipe. They can withstand higher...

The expansion of hot-rolled seamless steel pipe has two methods: vertical rolling expansion and cross-rolling expansion. The quality defects of longitudinal rolling expansion mainly include surface...

Welded pipes are common pipes in gas pipelines. Welded pipes with a diameter of more than 426mm (or 508mm) are generally called large-diameter welded pipes. Weld pipes can be classified into spiral...

The production process of spiral submerged arc pipe is more complicated than that of lsaw steel pipe. The proportion in steel pipe is stable at 42%~45% in recent years, and the welded pipe has a...

First, the hot-dip galvanized pipe is obtained by reacting a molten metal with an iron matrix to form an alloy layer, thereby combining the substrate and the plating layer.Hot-dip galvanizing is to...

Longitudinally submerged arc welding pipe production process is simple, high production efficiency, low cost and rapid development. The strength of the ssaw steel pipe is usually higher than that of...

When the seamless steel pipe is cold drawn, due to defects such as cracks in the hot rolled billet or high-precision cold drawn tubes being formed into the cylinder, almost no plastic deformation...

High temperature resistant cold drawn seamless steel pipe with excellent high temperature oxidation resistance. It has high temperature strength, oxidation resistance, carburization resistance, acid...

Steel pipes are often used in our lives. The most common ones are tap water pipes at home, mostly made of steel pipes. Because the hardness of the steel pipe itself is very high, it is not easy to be...

As we all know, the common seamless steel pipe and erw steel pipe have been widely used in life. The water pipe is an important part of the life pipe. It has a wide variety in the market, and many...

When many people purchase steel pipes in the market, they found that a steel pipe is very exquisite, and there is no seam on its surface. Many people have learned from the dealers that they have a...

Welded pipes are not seamless pipes. Many people understand and distinguish between seamless pipes and welded pipes. In fact, the distinction between the two is very easy. Below I teach you how to...

Poor appearance of steel surface often have Ma phenomenon.Mong surface is due to the groove caused by serious wear irregular steel surface irregularities defects. Due to the poor quality steel pipe...
