Tricon Steels & Alloys is a trusted supplier of high-quality piping solutions. ASTM A672 B70 Pipe is a carbon steel EFW pipe designed for high-temperature applications. Our pipes comply with standards such as API SPEC 5L, GB/T 9711.1, GB/T 9711.2, GB/T 9711.3 and SY/T5037 to achieve reliability and efficiency. They are manufactured using electrofusion welding techniques which provide structural integrity and strength.
ASTM A672 Gr B70 Pipe provides superior weldability, corrosion resistance, and toughness. The "B70" grade ensures a minimum yield strength of 70 ksi which makes them suitable for demanding industrial applications. They are used for high-pressure and high-temperature fluid transport in petrochemical, power generation and construction industries. Due to thier versatility, they are suitable for transporting water, steam and hydrocarbons. ASTM A672 B70 Carbon Steel EFW Pipe is also applied in the manufacture of machine parts and equipment because of their reliable performance even in harsh conditions.
Our ASTM A672 B70 Pipe specification includes various sizes, thicknesses and lengths to meet different project requirements. For seamless pipes the outer diameter extends from 3/8-36 inches and 18-56 inches for LSAW pipes. Wall thickness varies from 2-60mm and includes schedules such as SCH 10 - SCH 160 and XXS. Available in single and double random lengths, we offer pipes with end options such as plain, beveled, grooved and threaded with surface treatments like painting, galvanizing and anti-corrosion coatings.
Quality checks for ASME SA672 B70 Pipe ensure superior performance and compliance with industry standards. Various tests such as eddy current, hydrostatic and ultrasonic inspections are conducted to find defects. Chemical and mechanical tests confirm the material tensile strength, yield strength and chemical quality. As a leading ASTM A672 B70 Pipe Exporter, our packaging is done securely using strong steel strips for small pipes and plastic woven bags for large sizes ensuring safe transportation in containers or bulk shipments.

The Rolling and Welding Stage
To begin our process, we first need to go through the rolling and welding stage. The Carbon steel is placed through a checking process and cut at the edges in this stage.
Cleaning and Warming Stage
The rolled Carbon steel pipes thus manufactured are cut to the required lengths depending upon the industrial demand.
Cold-Drawing Stage
Sometimes, the required size isn’t obtained when the steel is brought through the mill directly. When using the cold-drawing process, the desired size is achieved when the pipes and tubing are coated with oxalic and soap solution and dragged over die plugs—the oxalic and soap solution help reduce friction when going through the cold cycle.
The Finishing Process
The final process is the finisher. Once the process of manufacturing ASTM A672 B70 and tubing is completed, you’ll now have to take them to a jet printer.
