Steel Pipe

A53 pipe is a general purpose pipe predominately used for mechanical and pressure applications at low to medium pressures. Transporting water, gas, steam, and air are all common applications. It is available in grade A and B. Grade A A53 is a seamless and electric-resistance-welded grade with a minimum tensile strength of 48,000 psi. Grade B has a higher tensile strength of at least 60,000 psi.

A500 is a relatively high strength steel often used for low to medium pressure applications, including the transport of water and gas. It is a high value steel with structural specification, commonly seen in the construction, agriculture, and transportation industries. It is easy to weld, machine, and can be cold worked.

This pipe grade is best for high-temperature service. It shows good shock resistance and can tolerate high pressure. This grade is often seen in power generation applications.

Stainless and carbon steel differ in their composition. Stainless steel must have at least 10% chromium content. The addition of chromium gives it greater corrosion resistance. Carbon steel has both a much higher carbon content, and lacks the added protection that chromium lends stainless, resulting in a greater susceptibility to rust. Check out our blog post on when to use carbon steel vs. stainless steel to learn more.

Galvanized steel is steel with a protective zinc coating. Galvanized steel protects against rust and is commonly seen across industries, including construction, automotive, manufacturing, and more.

The term schedule refers to the wall thickness of the pipe. Schedule 40 is a standard steel pipe. Note that the actual wall thickness is relative to the nominal pipe size (NPS). For example:

• For pipe size 1.000″ Schedule 40, the actual wall thickness is 0.133″
• For pipe size 2.000″ Schedule 40, the actual wall thickness is 0.145″

From the tool being used (saw, grinder, torch etc.) to the thickness of the metal being cut, the level of difficulty encountered when cutting any metal depends on a number of factors. Before cutting begins, ensure all PPE (safety goggles, safety gloves etc.) is on properly, and make adjustments if needed. Since pipes are hollow and round, they must be properly secured prior to cutting. Additional steps include measuring and marking the steel, and cutting and refining the edges as necessary.

Instrumentation fittings are used to connect pipes. They’re commonly welded or threaded, and are often leak proof. Sometimes fittings allow for valves and pumps to manage flow in pipes. Other applications, like handrails or bicycles do not require leak proofing.
