One of the most significant advantages of spiral welded tube is its superior strength, which exceeds that of straight seam welded pipe. This makes it ideal for projects that require enhanced structural integrity. In addition, due to its unique manufacturing process, spiral welded pipe can be produced using narrower steel billets, allowing the production of larger diameter pipes. Additionally, by utilizing blanks of the same width, we can effortlessly manufacture tubes of different diameters, further expanding its versatility.
With a strong commitment to quality, our company has invested significant resources in setting up state-of-the-art manufacturing facilities. The company covers an area of 350,000 square meters and has total assets of 680 million yuan. But what truly sets us apart is our dedicated team. Our workforce of 680 highly skilled professionals is the driving force behind our success.
We are proud of our annual production capacity of 400,000 tons of spiral steel tubes, exceeding industry standards. This unparalleled output has created an extremely high output value of 1.8 billion yuan. Our diligent team ensures that every device leaving our facility adheres to the strictest quality control measures, guaranteeing our customers superior quality.
In summary, spiral submerged arc welded pipes are a game changer for the steel pipe industry. With its superior strength, exceptional versatility and unparalleled reliability, it is the ultimate solution for all your welded pipe requirements. Cooperate with Cangzhou Spiral Steel Pipes Group Co., Ltd. today to experience the future of the steel pipe industry.
