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, is adjacent to Beijing and Tianjin to the north, and faces the Shandong and Liaodong Peninsulas across the sea. It is 240 kilometers from the capital Beijing, 120 kilometers from Tianjin, and 221 kilometers from the provincial capital Shijiazhuang. Cangzhou is centrally positioned in the Bohai Rim, designated as one of Hebei Province's "Two Rings" (Ring around Beijing-Tianjin and the Bohai Rim) open-line regions. It is also a strategic transportation hub connecting Beijing-Tianjin to the eastern coastal areas.

Based on our production and operation of steel pipes, we have developed concrete pile ultrasonic detection pipes, pile cap cooling pipes, grouting pipes, and subgrade settlement plates through the organization of talents and equipment. Our ultrasonic detection pipe products mainly include clamping-type, spiral-type, and sleeve-type detection pipes. The pile foundation detection pipes utilize sealing rings for reliable sealing and feature excellent tensile and twist resistance. These products strictly comply with "Steel Thin-Walled Ultrasonic Detection Pipes for Concrete Injections and Their Application Requirements," also known as "J1/1705-2007." They are widely used in national mega projects such as high-speed railways, expressways, high-rise buildings, and ports. Relying on our superior product quality, abundant inventory, prompt transportation, and after-sales service, we have established long-term cooperative relationships with major state-owned enterprises such as China Railway, China Communications Construction Corporation, China Water Conservancy and Hydropower Group, and China State Construction Engineering Corporation.

We will always adhere to the principle of "Quality First, Customer Supreme," providing excellent acoustic tube products for both national pile foundation construction and our vast customer base, striving to become a leading Chinese manufacturer of pile foundation acoustic tubes.
