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 from the capital city of Beijing, 120 kilometers from Tianjin, and 221 kilometers from the provincial capital Shijiazhuang. Cangzhou is situated in the central area of the Bohai Rim, designated as one of the "Two Rings" (Ring Beijing-Tianjin, Ring Bohai) opening-up zones by Hebei Province. It is also a key 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 concrete pile ultrasonic detection pipes, pile cap cooling pipes, grouting pipes, and subgrade settlement plates. Our ultrasonic detection pipe products include: clamping type, spiral type, and sleeve type. The pile foundation ultrasonic detection pipes achieve reliable sealing with a sealing ring and possess excellent tensile and twist resistance. These products strictly adhere to the "Steel Thin-Walled Ultrasonic Detection Pipes for Concrete Grouting Piles and Their Application Requirements," i.e., "J1/1705-2007." They are widely used in national large-scale projects such as high-speed rail, expressways, high-rise buildings, and docks. With our solid product quality, abundant inventory, quick and timely transportation, and after-sales service, we have established long-term cooperative relationships with major state-owned enterprises such as CRCC, CCCC, CWE, and CBCC.

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