Carbon steel pipes are a popular choice for underground infrastructure due to their strength and cost-efficiency. However, direct burial exposes them to complex soil environments containing moisture, oxygen, dissolved salts, and microorganisms. These factors trigger electrochemical reactions that ca
Read MorePipe elbows are critical components in industrial piping systems, but their unique geometry makes them highly susceptible to corrosion. The change in flow direction creates turbulence, uneven flow distribution, and increased friction, which can accelerate surface damage. When combined with exposure
Read MoreCold-drawn seamless steel pipes are essential for precision industries like automotive and hydraulics, offering superior dimensional accuracy and smooth surfaces. However, wall thickness uniformity is a critical quality indicator. Uneven wall thickness can compromise pressure resistance, increase ma
Read MoreFeatures:1. Low carbon steel tubing with seamless is a carbon steel with a carbon content of less than 0.25%. It is also called mild steel because of its low strength, low hardness and softness.2. The annealed structure of low carbon steel tubing with seamless is ferrite and a small amount of pearli
There are five main methods for detecting surface defects of square and rectangular tubes: 1. Eddy current inspection Eddy current testing includes basic eddy current testing, far-field eddy current testing, multi-frequency eddy current testing, and single-pulse eddy current testing. Using the eddy
The oil casing is short joint, causing this phenomenon due to internal mechanical failures such as roller or shaft eccentricity, or excessive welding power, or other reasons. As the welding speed increases, the tube blank extrusion speed increases. This facilitates the extrusion of the liquid metal
Weld leveling of straight seam steel pipe (lsaw/erw):Due to the impact of the welding current and the influence of gravity, the internal weld of the pipe will protrude, and the external weld will also sag. If these problems are used in an ordinary low-pressure fluid environment, they will not be aff
The production process of seamless steel pipes is relatively cumbersome and rigorous. After the seamless steel pipe is produced, certain tests must be carried out. Do you know the flattening test method and steps of the seamless steel pipe?1) Flatten the sample:1. The sample is cut from any part of
Spiral welded pipe (ssaw) is a kind of steel pipe that combines low-carbon and environmentally friendly alloy structural steel and low-alloy structural characteristics into pipe material and electric welding. How can the reliability of the spiral pipe be improved in the process of adoption?When we s
