Performance inspection methods for 304/304L stainless steel seamless pipes

304/304L stainless seamless steel pipe is one of the very important raw materials in the manufacture of stainless steel pipe fittings. 304/304L stainless steel is a common chromium-nickel alloy stainless steel with good corrosion resistance and high temperature resistance, which is very suitable ...

Storing galvanized steel products properly during the rainy season is important to prevent any damage or corrosion.

In the summer, there is a lot of rain, and after the rain, the weather is hot and humid. In this state, the surface of galvanized steel products is easy to be alkalization (commonly known as white rust), and the interior (especially 1/2inch to 1-1/4inch galvanized pipes) is prone to produce black...

Steel Gauge Conversion Chart

These dimensions may vary slightly depending on the specific material being used, such as stainless steel or aluminum. Here is the table that shows the actual thickness of sheet steel in millimetres and inches compared to gauge size: Gauge No Inch Metric 1 0.300″ 7.6mm 2 0.276R... Read More

what is the difference between EN39 S235GT and Q235 ?

EN39 S235GT and Q235 are both steel grades used for construction purposes. EN39 S235GT is a European standard steel grade that refers to the chemical composition and mechanical properties of the steel. It contains Max. 0.2% carbon, 1.40% manganese, 0.040% phosphorus, 0.045% sulfur, and less than ... Read More

who is Black annealed steel pipe ?

Black annealed steel pipe is a type of steel pipe that has been annealed (heat-treated) to remove its internal stresses, making it stronger and more ductile. The process of annealing involves heating the steel pipe to a certain temperature and then slowly cooling it down, which helps to minimize ... Read More

Type of Carbon Steel Pipe Coating

Bare Pipe : A pipe is considered bare if it does not have a coating adhered to it. Typically, once rolling is complete at the steel mill, the bare material is shipped to a location designed to protect or coat the material with the desired coating (which is determined by the ground conditions of t...

What is RHS , SHS and CHS ?

The term RHS stands for Rectangular Hollow Section. SHS stands for Square Hollow Section. Less known is the term CHS, this stands for Circular Hollow Section. In the world of engineering and construction, the acronyms RHS, SHS and CHS are often used. This is most common in the United Kingdom and... Read More

hot-rolled seamless steel pipe and a cold-rolled seamless steel pipe

Cold-rolled seamless steel pipes are often of small diameter, and hot-rolled seamless steel pipes are often of large diameter. The accuracy of cold-rolled seamless steel pipe is higher than that of hot-rolled seamless steel pipe, and the price is also higher than that of hot-rolled seamless steel... Read More

difference between pre-galvanized steel tube and hot-galvanized steel tube

Hot dip galvanized pipe is the natural black steel tube after manufacturing immersed in the plating solution. The thickness of the zinc coating is affected by a number of factors, including the surface of the steel, the time it takes to immerse the steel in the bath, the composition of the steel,...

Carbon steel

Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. Mild steel (iron containing a small percentage of carbon, strong and tough but not readily tempered), also known as plain-carbon steel and low-carbon steel, is now the most common form of steel because its pr...

ERW, LSAW Steel Pipe

Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. The production process of straight seam steel pipe is simple, with high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally hig... Read More
