Precautions for storing straight seam steel pipes:Most of the merchants did not use the straight seam steel pipe soon after purchasing it. So is there anything we need to pay attention to in the storage of straight seam steel pipes? The staff of straight seam steel pipe manufacturers reminded that t

The steel pipe pipeline is the main transportation channel for production. The supply of materials and the flow of the process are realized by pipelines of different specifications, pressure levels, and shapes. There are countless elbows, flanges, and welds in the running pipeline. If one of the int

In terms of the welding process, the welding method of spiral welded pipe and straight seam steel pipe is the same, but the straight seam welded pipe will inevitably have many T-shaped welds, so the probability of welding defects is also greatly increased, and the welding residue at the T-shaped wel

Important components of alloy steel and thick parts must be preheated before welding.The purpose of spiral steel pipe preheating before welding is as follows:(1) Preheating can slow down the cooling rate after welding so that hydrogen diffuses in the weld metal and escapes to avoid cracking caused b

Welding and cutting of the spiral steel pipe structure are inevitable in the application of the spiral steel pipe. Because of the characteristics of the spiral steel pipe itself, compared with ordinary carbon steel, the welding and cutting of the spiral steel pipe have its particularity, and it is e

①Advantages of material propertiesAs the name suggests, stainless steel 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. on the hot water pipe. At the same time, the stainless steel material has no exudate and can ach

As an efficient special means of transportation, pipeline transportation has played an increasingly important role in the fields of oil and natural gas transportation. At present, domestic large-diameter transportation pipelines are mainly constructed with spiral welded pipes. To ensure the reliable

The butt welding flange is that the pipe diameter and wall thickness of the interface end is the same as the pipes to be welded, and are welded like two pipes. The flat welding flange is a concave table that is slightly larger than the outer diameter of the pipe at the interface, and the pipe is ins

Product name: Seamless carbon steel pipeMaterial: Carbon steelSize: SCH 80x1/2''x5.8MStandard: ASTM A106Quantity: 7000 tonsMany cooperations have given the customer full confidence in THREEWAY STEEL.

1. The reasons for the uneven wall thickness of the spiral shape are: the uneven wall thickness caused by the adjustment reasons such as the uneven rolling centerline of the piercer, the inclination angle of the two rolls, or the reduction amount in front of the plug is too small, generally along th
