Based on our production and operation of steel pipes, our team and equipment have developed ultrasonic detection pipes for concrete pile foundations, pedestal cooling pipes, grouting pipes, and subgrade settlement plates. Our ultrasonic detection pipe products include: clamping-type, spiral-type, and sleeve-type pipes. The pile foundation ultrasonic detection pipes achieve reliable sealing with a sealing ring and possess reliable tensile and torsional resistance. These products strictly comply with the "Technical Requirements for Steel Thin-Walled Ultrasonic Detection Pipes for Concrete Grouting Piles" i.e., "J1/1705-2007," and are widely used in national major projects such as high-speed rail, expressways, high-rise buildings, and ports. With our superior 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 consistently adhere to the principle of "Quality First, Customers Supreme," providing top-quality acoustic pipe products for national pile foundation construction and our vast customer base, striving to become a leading Chinese manufacturer of pile foundation acoustic pipes.
