Advantages and Disadvantages of Hot-rolled Seamless Steel Pipe
Hot rolled is relative to the cold-rolled, cold rolling is below the recrystallization temperature of the rolling, and hot-rolled is carried out above the recrystallization temperature of the rolling.

What is ERW Steel Pipe?
ERW steel pipes are manufactured by low-frequency or high-frequency resistance "resistance". They are round pipes welded from steel plates with longitudinal welds. It is used to transport oil, natural gas, and other vapor-liquid objects, and can meet various requirements of high and low pressure. At present, it occupies a pivotal position in the field of transportation pipes in the world.

The Difference Between Pipes And Tubes?
One of the most frequent questions we get from customers is “What’s the difference between pipe and tube”? Although pipes and tubes may look similar, they are actually quite different in nomenclature and sizing. Remember that pipes and tubes are rarely interchangeable.

Difference Between Straight Seam Steel Pipe and Spiral Steel Pipe
The production process of straight seam steel pipes is relatively simple, and the main content of the production process is high-frequency welded straight seam steel pipes (ERW) and submerged arc welded straight seam steel pipes (LSAW). The production efficiency of straight seam steel pipes is high, the cost is low, and the economy develops rapidly. The strength design of spiral steel pipes (SSAW) is usually higher than that of straight seam steel pipes.

Difference Between Seamless Pipe And Welded Pipe
Welded pipe used the steel plate or steel strip as raw material, and it is welded after being crimped by the unit and mold. According to different welding methods, it can be divided into straight seam welded pipe and spiral welded pipe. While seamless steel pipe is made by cold rolling, cold drawing, or hot extrusion production process using round steel perforation as raw material.

Difference Between GI Steel Pipe And MS Pipe
Galvanized iron is iron that has been coated in a layer of zinc. The zinc layer is coated to help the metal resist corrosion. Steel can also be galvanized. When steel is used in an environment where corrosion and rust are easy to happen, we often put the steel galvanized. So the steel will have a longer service life than that not be galvanized. However, even with galvanization, corrosion will eventually start to occur, especially if conditions are acidic.

Difference Between Seamless Steel Pipe And Welded Steel Pipe
There are two types of steel pipe/tube. One type is a seamless steel pipe, and another type is the SAW steel pipe that has a single welded seam along its length. While SAW steel pipe can be divided into LSAW steel pipe and SSAW steel pipe. Both seamless steel pipe and seam steel pipe have different uses. The difference in the basic manufacturing method is obvious from the names. A seamless steel tube is extruded and drawn from a billet while the SAW tube is produced from a strip that is roll formed and welded to produce a tube.

Difference between SSAW Steel Pipe and LSAW Steel Pipe
SSAW steel pipe, whose full name is Straight seam submerged arc welding pipe. Longitudinally Submerged Arc Welded Steel pipes, which is abbreviated as LSAW steel pipe. These two types of pipes only have one letter’s difference, but they are truly different in their manufacturing process. Besides the manufacturing process, there are also other different aspects of these two types of pipe.
