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

Technical requirements for straight seam welded steel pipes:Technical requirements and inspection of straight seam welded steel pipes According to the GB3092 "Welded Steel Pipes for Low-Pressure Fluid Transport" standard, the nominal diameter of the welded steel pipe are 6~150mm, the nominal wall th

First, the accepted principle of spiral steel pipeThe quality inspection and acceptance of the spiral welded pipe shall be carried out by the technical quality supervision department of the supplier. The supplier must ensure that the delivered spiral welded pipe meets the requirements of the corresp
