We have developed concrete pile foundation ultrasonic detection pipes, pier cooling pipes, grouting pipes, and subgrade settlement plates based on our production of steel pipes. 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 offer excellent tensile and torsional resistance. These products strictly comply with the "Technical Requirements for Steel Thin-Walled Ultrasonic Detection Pipes for Concrete Grouting Piles" (J1/1705-2007). They are widely used in major national projects such as high-speed rail, expressways, high-rise buildings, and ports. With our superior product quality, abundant inventory, prompt delivery, and excellent after-sales service, we have established long-term cooperative relationships with major state-owned enterprises such as 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, Customer Supreme," providing excellent ultrasonic testing pipe products for both national pile foundation construction and a wide range of customers, striving to become a leading Chinese manufacturer of pile foundation ultrasonic testing pipes.
