In the field of industrial pipelines, standards are the guarantee of quality. Today, we will introduce you to the important standard ASTM A139 and present the high-quality spiral steel pipe products produced based on this standard.
Overview of ASTM A139 Standard
ASTM A139 is the "Standard Specification for Electric Fusion Welded Steel Pipes" formulated by the American Society for Testing and Materials. It specifically covers steel pipes produced using the electric fusion welding process. This standard encompasses five grades from A to E, mainly classified based on the minimum yield strength of the steel pipes, and is widely used in medium-pressure or high-pressure environments for the transportation of gases, water, oil, and other liquids.
ASTM A139 standard-compliant Astm Steel Pipes must undergo strict manufacturing process control and rigorous mechanical performance testing to ensure that each steel pipe has stable load-bearing capacity and reliable welding quality.
Innovative products based on ASTM A139
As a leading manufacturer of spiral steel pipes in China, Cangzhou Spiral Steel Pipe Group recently launched the S235 J0 spiral steel pipe based on the ASTM A139 standard. This product represents our latest breakthrough in the field of steel pipe technology.
This product adopts an advanced spiral steel pipe forming process and possesses the following notable advantages:
Uniform deformation control: The spiral forming process ensures that the steel plate is subjected to uniform force throughout the entire processing, avoiding local stress concentration.
Minimization of residual stress: Precise control of forming parameters ensures that the residual stress within the steel pipe is minimized, thereby enhancing the long-term stability of the product.
Excellent surface quality: Smooth and scratch-free surface treatment, reducing the difficulty of subsequent anti-corrosion coating application and extending the service life.
Enterprise strength guarantee
Founded in 1993, Cangzhou Spiral Steel Pipe Group is situated in Cangzhou, Hebei Province. It has become the largest manufacturer of spiral steel pipes and pipeline coating products in China. The company covers an area of 350,000 square meters with 68 million yuan total asset and 680 staff at present. 1.8 Billion RMB of annual output, 400,000 tons of spiral steel pipes per year.
We have always been bringing International Standards to Chinese Manufacturing for 30 years. Every Astm Steel Pipe that fulfils the ASTM A139 AWWA NSC standard is subjected to various inspection processes ranged in strictness during raw material procurement until delivery of the final product.
Choosing spiral steel pipes which conform to the ASTM A139 standard is a decision for safety, trustworthiness and durability. Cangzhou Spiral Steel Pipe Group is eager to cooperate with you to build long-lasting pipeline projects.
