Spiral Steel Pipe and LSAW Steel Pipe are two common types of welded steel pipe, and there are some differences in their manufacturing process, structural characteristics, performance and application.
Manufacturing process
1. SSAW pipe:
It is made by rolling strip stee...
The HEA series is characterized by narrow flanges and a high cross-section, offering excellent bending performance. Taking Hea 200 Beam as an example, it has a height of 200mm, a flange width of 100mm, a web thickness of 5.5mm, a flange thickness of 8.5mm, and a section ...
Difference in production process
Galvanized strip pipe (pre galvanized steel pipe) is a kind of welded pipe made by welding with galvanized steel strip as raw material. The steel strip itself is coated with a layer of zinc before rolling, and after welding into a pipe, ...
There are two main types of galvanized steel strip, one is cold treated steel strip, the second is heat treated enough steel strip, these two types of steel strip have different characteristics, so the storage method is also different.
After hot dip galvanized strip pro...
First of all, U-beam is a kind of steel material whose cross-section shape is similar to the English letter “U”. It is characterized by high pressure, so it is often used in automobile profile bracket purlin and other occasions that need to withstand greater pressure.
I...
In the field of oil and gas transportation, spiral pipe shows unique advantages over LSAW pipe, which is mainly attributed to the technical characteristics brought by its special design and production process.
First of all, the forming method of spiral pipe makes it poss...
There are five main detection methods for surface defects of Steel Square Tube:
(1) Eddy current detection
There are various forms of eddy current detection, commonly used conventional eddy current detection, far-field eddy current detection, multi-frequency eddy curren...
General welded pipe: general welded pipe is used to transport low pressure fluid. Made of Q195A, Q215A, Q235A steel. Can also be easy to weld other soft steel manufacturing. Steel pipe to water pressure, bending, flattening and other experiments, there are certain requir...
As a commonly used support structure, steel sheet pile is widely used in deep foundation pit support, levee, cofferdam and other projects. The driving method of steel sheet piles directly affects the construction efficiency, cost and construction quality, and the choice ...
What is wire rod
In layman's terms, coiled rebar is wire, that is, rolled into a circle to form a hoop, the construction of which should be required to straighten, generally the diameter of 10 or less.
According to the diameter size, that is, the degree of thickness, and...
The heat treatment process of seamless steel pipe is a process that changes the internal metal organization and mechanical properties of seamless steel pipe through the processes of heating, holding and cooling. These processes aim to improve the strength, toughness, wea...
The predecessor of color steel plate is: Hot Dip Galvanized Steel Plate, hot aluminized zinc plate, or aluminum plate and cold rolled plate, the above types of steel plate is the color steel plate substrate, that is to say, no paint, baking paint steel plate substrate, t...
