Cangzhou Tianhai Steel Pipe is a deep-processing steel pipe enterprise in the Jingjinji region. Located in the southeastern part of Hebei Province, Cangzhou borders the Bohai Sea to the east, and is adjacent to Beijing and Tianjin to the north. It faces the Shandong Peninsula and the Liaodong Peninsula across the sea. It is 240 kilometers away from the capital Beijing, 120 kilometers from Tianjin, and 221 kilometers from the provincial capital Shijiazhuang. Cangzhou is situated in the central part of the Bohai Rim, designated as an "open first-line area" of the "Two Rings" (Ring Beijing-Tianjin and Bohai Rim) by Hebei Province. It is also a strategic transportation hub connecting Beijing-Tianjin to the eastern coastal regions.

Based on our production and operation of steel pipes, our team and equipment have developed ultrasonic concrete pile foundation testing pipes, foundation mat cooling pipes, grouting pipes, and subgrade settlement plates. Our ultrasonic testing pipe products include: clamping-type, spiral-type, and sleeve-type testing pipes. The pile foundation testing pipes utilize sealing rings for reliable sealing and also feature reliable tensile and torsional resistance. These products strictly comply with the "Technical Requirements for Steel Thin-Walled Ultrasonic Testing Pipes for Concrete Grouting Piles" (J1/1705-2007). They are widely used in national major projects such as high-speed rail, expressways, high-rise buildings, and harbors. Backed by superior product quality, ample inventory, prompt transportation, and excellent after-sales service, we have established long-term cooperative relationships with large state-owned enterprises like China Railway, China Communications Construction Corporation, China Power Investment Corporation, and China State Construction Engineering Corporation.

We will always adhere to the principle of "Quality First, Customer Supreme," providing excellent ultrasonic pipeline products for both national pile foundation construction and our wide customer base, striving to become a leading Chinese manufacturer of pile foundation ultrasonic pipelines.
