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 front-line regions by Hebei Province. It is also a strategic 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 ultrasonic testing pipes for concrete pile foundations, pier cooling pipes, grouting pipes, and subgrade settlement plates. Our ultrasonic testing pipe products mainly include: clamping-type, spiral-type, and sleeve-type testing pipes. The pile foundation testing pipes achieve reliable sealing with a sealing ring and possess excellent tensile and torsional resistance, strictly adhering to the "Technical Requirements for Ultrasonic Testing Pipes for Concrete Grouting Piles" (J1/1705-2007). These products are widely used in major national projects such as high-speed rail, expressways, high-rise buildings, and ports. With our solid product quality, ample 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 Water Resources and Hydropower Engineering Group, and China State Construction Engineering Corporation.

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