In the construction sequence of steel pipe piles, we should first grasp all aspects of the project for comprehensive consideration and analysis, such as construction machinery, construction period, design requirements, geomorphic environment, engineering volume, layout, steel pipe pile specification

First, methods for preheating deformation of straight seam steel pipes: 1. Reasonable material selection. For precision and messy molds, micro-deformation mold steels with good quality should be selected. For mold steels with serious carbide segregation, reasonable casting quenching and tempering h

Straight seam steel pipes are steel pipes with welds parallel to the longitudinal direction of the steel pipe. They are usually divided into metric electric welded steel pipes, electric welded thin-walled pipes, transformer cooling oil pipes, etc. The production process of straight seam welded pipes

The main processing methods for large-diameter steel pipes are: 1. Forging steel: a pressure processing method that uses the reciprocating impact force of the forging hammer or the pressure of the press to change the blank into the shape and size we need. 2. Extrusion: It is a processing method in

Do you know how spiral steel pipes are sawed off? Are there any issues that need attention? Here is a brief introduction for everyone. After a series of processes such as forming, welding, and cooling, spiral steel pipes still need to be sawed. In this link, the length of the technical spare rule

Slag inclusion in welded steel pipes is slag remaining inside the weld. From a theoretical analysis, the main reasons for slag inclusion in submerged arc automatic welding welds are the following three points: ① There are many inclusions in the raw materials (including parent materials, welding wire

First, the introduction of the high-frequency welding process of submerged arc steel pipe: 1. Control of weld gap: After multiple rollers roll, the strip steel is fed into the welded pipe unit. The strip steel is gradually rolled up to form a round tube blank with a tooth gap. The pressing amount o

First, straight seam steel pipe production temperature: In the process of producing straight seam steel pipes, the temperature must be strictly controlled to ensure the reliability of welding. If the temperature is too low, the welding position may not reach the temperature required for welding. Wh

First, the leakage location and condition. The bolts connecting the flanges on both sides of the DN150 valve body are leaking. Due to the extremely small gap between the flange connections, it is impossible to eliminate the leakage by injecting sealant through the gap. The leakage medium is steam, t

1. Quality defects and prevention of tube billets: The tube billets used in the production of seamless steel pipes can be either continuous casting round tube billets, rolled (forged) round tube billets, centrifugally cast round hollow tube billets, or steel ingots can be used directly. In the actua

In the steel industry, seamless steel pipe is a common and widely used steel product. 1. What is a 48-inch seamless steel pipe? 48-inch seamless steel pipe is a seamless steel pipe specification with a specific outer diameter and wall thickness. In this specification, "48 inches" means that the
