Our pipes are made by rolling low-carbon structural steel into tube blanks at precise spiral angles, followed by a robust welding process to ensure the integrity and durability of the seams. This innovative manufacturing technique allows us to create large diameter steel pipes that are not only strong but also versatile, making them ideal for a wide range of uses from construction to oil and gas transportation.

Our factory is located in the heart of Cangzhou City, Hebei Province and has been a leader in the steel pipe industry since its establishment in 1993. The factory covers an area of 350,000 square meters and is equipped with state-of-the-art technology and machinery, enabling us to produce high-quality steel pipes that meet international standards. With total assets of RMB 680 million and 680 dedicated employees, we pride ourselves on our commitment to excellence and customer satisfaction.

Hydrostatic Test

product-description1

The pipe shall withstand the hydrostatic test without leakage through the weld seam or the pipe body
Jointers need not be hydrostatically tested, providedthat the portions of pipe used in marking the jointers were successfully hydrostatically tested prior to the joining operation.

Product Advantage

1. One of the main advantages of our spiral welded carbon steel pipes is the ability to produce large diameter pipes. This is achieved through a unique manufacturing process that involves rolling mild structural steel into tube blanks at a specific helical angle and then welding the seams.

2. This approach not only increases the strength and durability of the pipe, but also allows for flexibility in design and application.

3. our pipes are corrosion-resistant and can withstand high pressures, making them ideal for a variety of industries including oil and gas, water supply, and construction.

Product shortcoming

1. The manufacturing process, while efficient, can lead to quality variations if not monitored closely.

2. The initial cost of high-quality steel pipe may be higher than lower-grade alternatives, which may be a consideration for budget-sensitive projects.

3.While our pipes are designed to be durable, they may require regular maintenance to ensure longevity, especially in harsh environments.
