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 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 in the central area of the Bohai Rim, Cangzhou is designated as one of the "Two Rings" (Ring Beijing-Tianjin, Ring Bohai) opening-up zones by Hebei Province. It also serves as a crucial transportation hub connecting Beijing-Tianjin to the eastern coastal areas.

Based on our production and operation of steel pipes, our team and equipment have developed concrete pile ultrasonic testing pipes, foundation mat cooling pipes, grouting pipes, and subgrade settlement plates. Our ultrasonic testing pipe products mainly include: clamping-type, spiral-type, and sleeve-type ultrasonic testing pipes. The pile foundation ultrasonic testing pipes achieve reliable sealing with a sealing ring and possess reliable tensile and torsional resistance. These products strictly comply with the "Technical Requirements for Steel Thin-Walled Ultrasonic Testing Pipes for Concrete Grouting Piles" i.e., "J1/1705-2007," and are widely used in national major projects such as high-speed rail, expressways, high-rise buildings, and ports. With our superior product quality, abundant inventory, 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 always adhere to the principle of "Quality First, Customer Supreme," providing excellent acoustic pipe products for both national pile foundation construction and our wide range of customers, striving to become a leading Chinese manufacturer of pile foundation acoustic pipes.
