Cangzhou Tianhai Steel Pipe is a deep-processing steel pipe enterprise in the Jingjinji region. Located in the southeastern part of Hebei Province, Cangzhou is east of the Bohai Sea, north of Beijing and Tianjin, and 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. Situated at the center of the Bohai Rim, Cangzhou is designated as an "open first-line area" of the "Two Rings" (Ring Beijing-Tianjin, Ring Bohai) by Hebei Province and is a key transportation hub for accessing the eastern coastal regions from Beijing and Tianjin.

Based on our production and operation of steel pipes, we have developed concrete pile foundation ultrasonic testing pipes, foundation mat cooling pipes, grouting pipes, and subgrade settlement plates through the talents and equipment we organized. Our ultrasonic testing pipe products mainly include: clamp-type ultrasonic pipes, spiral-type ultrasonic pipes, and sleeve-type ultrasonic pipes. The pile foundation ultrasonic testing pipes utilize sealing rings to achieve reliable sealing, while also possessing reliable tensile and torsional resistance. Our products strictly adhere to the "Steel Thin-Walled Ultrasonic Testing Pipes for Concrete Grouting Piles and Their Application Requirements," which is the "J1/1705-2007." They are widely used in national major projects such as high-speed railways, expressways, high-rise buildings, and ports. Backed by superior product quality, ample stock, quick and timely 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 consistently adhere to the principle of "Quality First, Customer Supreme," providing excellent acoustic tube products for both national pile foundation construction and a wide range of customers, striving to become a leading Chinese manufacturer of pile foundation acoustic tubes.
