On the basis of our steel pipe production and operation, our personnel and equipment have developed concrete pile ultrasonic testing pipes, pile cap cooling pipes, grouting pipes, and subgrade settlement plates. Our ultrasonic testing pipe products mainly include: clamp-type ultrasonic pipes, helical ultrasonic pipes, and sleeve-type ultrasonic pipes. The pile foundation ultrasonic testing pipes utilize sealing rings for reliable sealing, and also possess reliable tensile and torsional resistance. Our products strictly comply with the "Technical Specifications for Ultrasonic Testing 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. Backed by our superior product quality, ample inventory, quick and timely transportation, and excellent after-sales service, we have established long-term cooperative relationships with major state-owned enterprises such as CRCC, CCCC, China Water & Power, and China Construction.

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.
