Carbon Steel Product Introduction:

The complex chemical and physical properties of the various grades of carbon steel pipe allow for a broad range of service usage. American Piping Products has the right grade, size and price to meet your requirements, including A/SA-106 GRADE B/C and API 5L X-42 thru X-70. A/SA-106 Grades B & C are utilized for services ranging from structural supports to steam drum headers with temperature ranges up to 800°F, while API 5L X Grades 42 thru 70 are utilized for the water and petroleum industry to transport liquids or as platforms on off-shore rigs.

Benefits of Carbon Steel Piping

Carbon steel piping is a durable material made from carbon steel, a steel alloy with iron and carbon. Because of its strength and ability to withstand stress, carbon steel pipe is used in a variety of heavy-duty industries like infrastructure, ships, distillers, and chemical fertilizer equipment.
 
Carbon Steel Pipes

The incredible strength of carbon steel means that carbon steel pipe can be made thinner and with less material while still being able to transport high volumes. This makes carbon steel piping a cost-effective material. Not only can less of it be used, but carbon steel is also recyclable, making it both environmentally-friendly and cost-effective.
 
Because it's easy to manufacture, carbon steel piping is a versatile material. We can make it in a variety of thicknesses and dimensions. It's also easy to cut and bent to fit wherever it's needed. Its also easily connected to joints, valves, and other pipe fittings.

Advantages of spiral welded pipe:

(1) Steel pipes of different diameters can be produced using strip steel of the same width, and steel pipes of large diameter can be produced from narrow strip steel.

(2) Under the same pressure conditions, the stress of the spiral welded seam is smaller than that of the straight seam, which is 75% to 90% of that of the straight seam welded pipe, so it can withstand greater pressure. Compared with the straight seam welded pipe of the same outer diameter, the wall thickness can be reduced by 10% to 25% under the same pressure.

(3) The size is accurate, the general diameter tolerance does not exceed 0.12%, the deflection is less than 1/2000, and the ovality is less than 1%. Generally, the sizing and straightening process can be omitted.

(4) Continuous production is possible. In theory, long steel pipes can be produced, with small head and tail loss, and can
increase the metal utilization rate by 6% to 8%.

(5) The equipment is light in weight and low initial investment. It can be made into a trailer-type mobile unit to directly produce welded pipes at the construction site where the pipeline is laid.

Standard Carbon Steel Pipe Specifications & Grades

A/SA-106 

ASTM A106 seamless steel pipe (also known as ASME SA106 pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.
Scope

ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 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.

Process

Killed steel, with primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining.
