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 the cities of Beijing and Tianjin to the north. It faces the Shandong Peninsula and the Liaodong Peninsula across the sea. The city 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" region in Hebei Province's "Two Rings" (Ring Beijing-Tianjin, Ring Bohai Rim). It is also a strategic transportation hub connecting Beijing-Tianjin to the eastern coastal areas.

On the basis of our steel pipe production and operation, our organized talent and equipment have developed and manufactured ultrasonic concrete pile foundation detection pipes, pier cooling pipes, grouting pipes, and subgrade settlement plates. Our ultrasonic detection pipe products mainly include: clamping-type ultrasonic pipes, spiral-type ultrasonic pipes, and sleeve-type ultrasonic pipes. The pile foundation ultrasonic pipes utilize sealing rings to achieve reliable sealing and also possess reliable tensile and torsional resistance. The products strictly comply with "Ultrasonic Detection Pipes for Concrete Grouting Piles and Application Requirements" i.e., "J1/1705-2007," and are widely used in major national projects such as high-speed railways, expressways, high-rise buildings, and harbors. 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 such as CRCC, CCCC, CCCC-Hydro, and CBCC.

We will consistently adhere to the principle of "Quality First, Customer Supreme," providing excellent acoustic pipe products for both national pile foundation construction and a wide range of customers, striving to become a leading Chinese manufacturer of pile foundation acoustic pipes.
