Many things have never been seen in the materials produced by construction projects, and they must be studied and studied. Here are some points that should be paid attention to in the purchase of straight seam steel pipes.1. Purchasing needs to know the types of steel pipes:a. According to the type:
Galvanized steel pipe, commonly known as cold galvanized pipe, adopts an electroplating process, only the outer wall of the steel pipe is galvanized, and the inner wall of the steel pipe is not galvanized. The hot-dip galvanized steel pipe adopts the hot-dip galvanizing process, and the inner and ou
Duplex stainless steel pipe fittings combine the performance characteristics of 304 and austenitic stainless steel pipe fittings. This paper compares the duplex stainless steel pipe fittings with the stainless steel pipe fittings with 304 and 316L as the main material, and draws the following differ
Regarding improving the stability of the spiral welded submerged arc welded steel pipe, the main issue is the storage of the spiral welded submerged arc welded steel pipe. When many customers consult with us, they often say that our spiral welded submerged arc welded steel pipe is placed in the Wher
Seamless Steel Elbow: Steel Elbow is a type of pipe fitting used in pipe bends. Among all the pipe fittings used in the piping system, the proportion is about 80%. Usually, different forming processes are selected for steel elbows of different materials or wall thicknesses. Commonly used seamless st
The welding seam of the spiral steel pipe is longer than that of the straight seam steel pipe. If the pipe length is L, the welding seam length is L/cos(θ). The vast majority of steel pipe defects are concentrated in the weld and heat-affected zone. The long weld means that the probability of defect
①Advantages of material propertiesAs the name suggests, the thin-walled stainless steel water pipe is made of stainless steel. 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 at 30 meters per seco
In the use of straight seam steel pipes in daily projects, the safe placement of straight seam steel pipes in projects is particularly important. How to properly place straight seam steel pipes?1. When the straight seam steel pipe is hoisted, the wire rope is not allowed to be pulled diagonally to p
With the increase in the use frequency of thick-walled seamless steel pipes in industry and life, the purchase of thick-walled seamless steel pipes has gradually increased, and manufacturers of thick-walled seamless steel pipes on the market have also emerged. Seam steel pipes are also mixed, so how
Large-diameter steel pipes are used more and more in daily projects, and more and more people are asked about how large-diameter steel pipes are formed in daily communication with buyers. How about large-diameter steel pipes? What about molding?1. Hot push system expansion method. The pushing and ex
