Each adapter flange is rigorously tested to ensure it meets the specified pressure requirements, ensuring reliability and safety in critical applications.


Company profile

Qingdao Tontr Pipeline System Co., Ltd. is located in Jiaozhou City, Qingdao City, Shandong Province, China.  Founded in 2015, the company has not been established for a long time, but its technical R&D personnel have been engaged in the pipeline industry for more than 20 years.

We mainly develop and produce remote liquid supply systems.  The longest distance project I have done is 6000 meters.  The company has a cost-saving corrosion resistant steel pipe processing technology.  The company self-made stainless steel pipe, through a series of operations to make the stainless steel pipe and the inner wall of the machine completely fit.  This can not only meet the corrosion resistance requirements of the same grade of stainless steel, but also meet the requirements of the same pressure of the steel pipe.  Greatly save costs, save raw materials.  Grooves are machined at both ends of the steel pipe, and the connection between the steel pipe and the steel pipe and the fitting is connected by a grooved coupling.
