Welded & Seamless Tested Pipe Supplier

ASTM A53 seamless and welded steel pipe is a general, all-purpose pipe. Designed for coiling, bending, and flanging, A53 carbon steel pipe is suitable for welding. The grades denote certain chemical and mechanical properties and should be noted in the selection. A53 pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines, Low pressure systems, Structural applications, Mechanical components, Bollards, Casing, generator plants, refineries, compressor stations, natural gas transmission, and steam conduction.

A53 Pipe Tolerances

ASTM A106 seamless steel pipe covers seamless carbon steel nominal wall pipe for high-temperature service, suitable for bending, flanging, and similar forming operations. NPS 1-1/2 and under may be either hot-finished or cold-drawn. NPS 2 and larger shall be hot-finished unless otherwise specified. Surface finish standards are outlined in the specification.

A106 pipe is always produced by the seamless method and can be bent, coiled and flanged and is intended for use in high-temperature applications, Pressure systems, Mechanical components, Structural applications, and Spreader bars.

The manufacturing process differs depending on the particular type and grade of ASTM A53 that it is.  The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic oxygen. The weld seam of the electric-resistance welded pipe in Grade B shall be heat treated after welding.  Below are the different types available in ASTM A53 pipe. 

The following types & grades of A53 pipe are covered within the ASTM A53 specification:

• Type F – Furnace-butt-welded, continuous welded Grade A
• Type E- Electric-resistance-welded, Grades A and B
• Type S- Seamless, Grades A and B

The manufacturing process for ASTM A106 seamless pipe starts with killed steel, with the primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining.  Steel cast in ingots or strand cast is permissible.  That bar is then rolled and pierced to produce a true seamless pipe. The hot-finished pipe does not need to be heat treated.  The cold-drawn pipe is heat treated after the final cold draw pass.

ASTM A53 pipe is pressure tested to allow for liquids and gases to be passed through it.

Carbon steel pipes can be resistant to corrosion due to the addition of lacquer coating, hot-dipped galvanizing, or zinc coating.  This allows builders to use smaller, thinner pipes, even in environments that are acidic or extremely corrosive.

A53 steel pipe offers great resistance to vibration and shock.

This tested steel pipe has high tensile strengths which make it safe to use in situations with very high pressures.

No matter the pressure that needs to be withstood, carbon A53 steel pipe can be much thinner than other types of pipes. This means that they have a greater carrying capacity than other pipes.

A53 steel pipe is best suited for the transport of air, water, steam, and oil in low to medium-pressure applications across the industrial spectrum. It’s also commonly used as structural steel.  Because of this, it can be used in almost any industry and environment in which liquids and/or gases are being moved.  This includes oil and gas, buildings, housing, and heavy equipment.

A106 steel pipe is best suited for the transport of air, water, steam, and oil in high-pressure applications across the industrial spectrum.  Because of this, it can be used in almost any industry and environment in which liquids and/or gases are being moved.  A106 pipe is formulated specifically for high-temperature and high-pressure service, usually in power generation applications. High-pressure, high-heat service environments put added stress on pipe, so seamless pipe types are preferred in those settings since they’re at less risk of failure under stress than their welded counterparts.
