Cangzhou Tianhai Steel Pipe is a deep-processing steel pipe enterprise located in the Jingjinji region. Situated in the southeastern part of Hebei Province, it borders the Bohai Sea to the east, is adjacent to Beijing and Tianjin to the north, and faces the Shandong and Liaodong peninsulas across the sea. It is 240 kilometers away from the capital city of Beijing, 120 kilometers from Tianjin, and 221 kilometers from the provincial capital of Shijiazhuang. Cangzhou is centrally positioned in the Bohai Rim, designated as an open front-line region for "Two Rings" (Ring Beijing-Tianjin and Ring Bohai) by Hebei Province. It also serves as a crucial transportation hub for the Beijing-Tianjin area to access the eastern coastal regions.

We, based on our production and operation of steel pipes, have developed concrete pile ultrasonic detection pipes, foundation mat cooling pipes, grouting pipes, and subgrade settlement plates with the talents and equipment we organized. Our ultrasonic detection pipe products mainly include: clamp-type, spiral-type, and sleeve-type detection pipes. The pile foundation detection pipes utilize sealing rings for reliable sealing and feature reliable tensile and torsional resistance. These products strictly comply with "Technical Requirements for Steel Thin-Walled Ultrasonic Detection Pipes for Concrete Grouting Piles" i.e., "J1/1705-2007," and are widely used in major national projects such as high-speed rail, expressways, high-rise buildings, and docks. With our solid 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.
