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 bordered by the Bohai Sea to the east, and is adjacent to Beijing and Tianjin to the north. It faces the Shandong Peninsula and the 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. Cangzhou is situated in the central area of the Bohai Rim, and is designated as one of the "two rings" (ring Beijing-Tianjin and 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.

We have developed concrete pile ultrasonic testing pipes, foundation mat cooling pipes, grouting pipes, and subgrade settlement plates based on our experience in steel pipe production and operation. Our ultrasonic testing pipe products include clamp-type, spiral-type, and sleeve-type pipes. These pile foundation testing pipes achieve reliable sealing with O-rings and possess excellent tensile and torsional resistance, adhering to the "Technical Requirements for Steel Thin-Walled Ultrasonic Testing Pipes for Concrete Grouting Piles" standard, i.e., J1/1705-2007. They are widely used in major national projects such as high-speed rail, expressways, high-rise buildings, and ports. Backed by our high-quality products, ample inventory, swift transportation, and exceptional after-sales service, we have established long-term cooperative relationships with major state-owned enterprises like China Railway, China Communications Construction Corporation, China Water Resources Group, and China State Construction Engineering Corporation.

We will always 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.
