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.

Differences Between Casing Coupling and Tubing Coupling
There are couplings for casing and couplings for tubing, the function is the same that to connect the pipe to each other. On the other hand, still, there are some differences between the two.

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.

Pipe Diameter VS Tube Diameter
Steel tube is generally used for structural purposes and the OD is an important and exact number. Steel tube size is specified by OD and the wall thickness, and the measured OD and stated OD are generally within very close tolerances of each other. Steel tube is usually more expensive than the steel pipe due to tighter manufacturing tolerances. Interestingly, while the stated and measured OD’s of steel tubes are almost exact most of the time, steel tube generally has a measured OD that is 1/8” larger than stated OD.

ANSI Standard of Stainless Steel Pipe
Stainless steel pipe is one of the more standardized materials in the building and engineering industries. The thickness of the pipe walls, the diameter of the pipe and even the chemical composition are all written as part of the American National Standards Institute standards (abbreviated as ANSI), which is just one of multiple standards available.

What Are Steel Pipes?
Steel pipes are long, hollow pipes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded pipe or a seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld. The first methods for producing steel pipe were introduced in the early 1800s, and they have steadily evolved into the modern processes we use today. Each year, millions of tons of steel pipe are produced. Its versatility makes it the most often used product produced by the steel industry.
