Company profile

Qingdao Tongchuang Pipeline System Co., Ltd. is located in the coastal city of Qingdao, China. Since its establishment, it has been committed to the development of high-quality piping systems and accessories.

It usually supplies coal and fire protection, but also oil and municipal services. A complete pipeline system generally includes seamless steel pipe, steel pipe coupling, flat gate valve, elbow and other steel pipe accessories.

The seamless steel pipe is independently developed and lined with stainless steel, which increases the corrosion resistance of the inner wall of the steel pipe and increases the service life of the steel pipe. The steel pipe coupling is developed from a single groove to a multi-groove, the use of double groove coupling pressure can reach 20 mpa, the use of three groove coupling pressure can reach 40 mpa, the test pressure before the factory is twice the use pressure.

Tontr pipeline system all use groove connection, foreign countries may use more flange connection, we used to use flange connection, but the flange connection bearing capacity is small, the installation steps are cumbersome, so we developed a groove connection.
