Company profile

Qingdao Tontr Pipeline System Co., Ltd. is committed to the development and production of high pressure pipeline systems. At present, the maximum pressure of normal working environment reaches 40 mpa.

The remote liquid supply system usually supplies the coal mine, and the general function is to send the emulsion to the hydraulic support through a certain pressure. Hydraulic support after the completion of reflux, reduce the waste of emulsion.

A complete remote liquid supply system usually includes steel pipe, coupling, gate valve, elbow, positive tee, filter, safety valve and other products. This paper mainly introduces the normal tee. The so-called positive tee means that the three ports are of the same caliber. Convenient diversion from the main road. The three ports are connected by grooves for easy installation. The pipe fittings are all galvanized inside and outside to enhance the corrosion resistance of the pipe fittings.

Company advantages

1.High material strength, small footprint, customizable conversion angle, easy installation and maintenance.

2. Professional technicians. Engaged in the pipeline industry for more than 20 years, has rich experience in R & D and production.

3.The physical factory has its own production workshop, and the production schedule and product quality can be monitored in real time.

4.Price concessions, no middleman links, reduce the middleman to earn the difference

TONTR is located in the beautiful coastal city of Qingdao. It is a professional national-level high-tech industry engaged in the design, development, manufacture and sales of high-pressure pipeline systems.
