What is an X70 pipe?

In the current era of rapid development in the construction and infrastructure industries, reliable and durable pipeline solutions have become the key to project success. As a leading manufacturer of spiral steel pipes and pipeline coating products in China, Cangzhou Spiral Steel Pipes Group Co., Ltd. has launched X70 SSAW Line Pipe , which is defining the new generation of Line Pipe standards with its outstanding performance. 

Line Pipe

X70 pipeline is a core product of high-grade pipeline steel, with a yield strength of over 485 MPa, adhering to strict standards such as API 5L and GB/T 9711. It combines high strength with excellent toughness and can easily handle multiple challenges such as high pressure and corrosion in underground installations. It adopts the advanced spiral submerged arc welding (SSAW) process, where the steel strip is wound helically and then welded. The weld stress is evenly distributed, giving the pipeline extraordinary compressive strength and corrosion resistance, especially suitable for underground gas pipelines, foundation engineering, and other critical scenarios. The product specifications range from 219mm to 3500mm, with single lengths up to 35 meters, perfectly meeting the needs of various large-scale infrastructure and specialized applications.

Based on the technical accumulation since its establishment in 1993, Cangzhou Spiral Steel Pipes Group Co., Ltd. is a powerful entity: its factory covers an area of 350,000 square meters, with total assets of 680 million yuan, and has 680 employees. Its annual production capacity of spiral steel pipes reaches 400,000 tons, with an annual output value of 1.8 billion yuan. The company strictly controls the entire process from raw material selection to product inspection, conducting multiple tests such as radiographic testing and ultrasonic flaw detection to ensure long-lasting service life and stable performance. As a Line Pipe solution that combines quality and versatility, X70 SSAW Line Pipe is not only suitable for underground gas and water transportation, but also performs well in long-distance pipeline laying and industrial fluid transmission scenarios, becoming a trusted choice for global infrastructure projects.
