Thick-walled steel pipe production steps:1. The stainless steel elbow is made of thick-walled steel pipe, and the wall thickness changes along the length of the pipe;2. Process the section of the square tube, and change the circular area into a square, oval, and polygon;3. For square pipes with crim

Thick-walled steel pipes are specified in the project:Corresponding regulations and various regulations for the practical selection and use of thick-walled pipe fittings. When thick-walled steel pipe and thick-walled pipe fittings are selected or used, they must first follow the corresponding regula

①Advantages of material propertiesThe thin-walled stainless steel pipe is made of stainless steel as the name implies. The strength of stainless steel is 3 times that of copper pipe and 8 to 10 times that of PPR pipe. It can withstand the impact of high-speed water flow of 30 meters per second; Espe

How to package the spiral steel pipe has always been a problem that needs attention. Next, I will tell you about the precautions for packaging spiral sense.1. If the buyer has special requirements for the packaging material and packaging method of the spiral steel pipe, it should be specified in the

The process is as follows: after the straight pipe is cut, the induction coil is put on the part to be bent by the bending machine, the pipe head is clamped by the mechanical arm, and the intermediate frequency current is passed into the induction coil to heat the steel pipe. When the temperature of

Acceptance of straight seam steel pipe:1. The inspection and acceptance of straight seam steel pipes shall be carried out by the technical supervision department of the supplier.2. The supplier ensures that the delivered straight seam steel pipe meets the requirements of the corresponding product st

1. The importance of anti-corrosion of long-distance natural gas anti-corrosion steel pipesAt this stage, both domestically and foreign, the demand for natural gas is gradually increasing, among which natural gas has become an irreplaceable and important energy source. In this case, the demand for n

Simply put, the process of heating the steel pipe and controlling it to be above the recrystallization temperature for rolling is called hot rolling. The process of rolling below the recrystallization temperature, including normal temperature, is called cold rolling.Hot-rolled steel pipe has good pl

1. Spiral steel pipes shall not be stacked with acid, alkali, salt, cement, and other materials that are corrosive to steel in the warehouse. Different varieties of steel should be stacked separately to prevent confusion and contact corrosion;2. Large sections, rails, steel plates, large-diameter sp

1. Compared with 304 stainless steel pipe, the advantages of duplex stainless steel pipe are as follows:(1) The yield strength is more than double that of ordinary austenitic stainless steel, and it has sufficient plastic toughness required for forming. The wall thickness of storage tanks or pressur
