It is under the jurisdiction of command of Chinese Academy of Building Materials Science, is a science and technology production enterprise specializes in development, production and selling of the sealing elements.

The company has a history of more than 20 years in sealing industry. With its ability in sealing technology and manufacturing of PU materials and filled PTFE products, and the development concept focusing on customer needs, the company has a strong problem-solving ability in chemical corrosion resistance, abrasion resistance, high and low temperature resistance and special media resistance. It provides advanced and reasonable sealing solutions for many customers. The sealing products have been applied in China Petroleum, Sinopec, metallurgical machinery and other industries. The sealing elements produced by the company are compliance with international standards API5CT-2018GB/T9711-2017GB/T8163-2018GB/T3091-2015 (the sealing bearing pressure reaches 200MPa), which is in the leading position in this industry. The products also cover cylinder seal, rotary seal, metallurgical seal such as steel-making and rolling pipe, special seal for oil well fracturing in petroleum and petrochemical industry, scroll seal for air conditioning in new energy automobile industry, etc.

Our company has independently developed and produced the main driving seals and articulated seals for full-face tunnel boring machines. It has made outstanding contributions to the localization of the main drive seal of shield machine and filled in the blank of domestic production of shield sealing rings. The products are suitable for different types of shield machines, such as earth pressure, mud, TBM, etc. and can be applied to the construction of different equipment under different geological conditions. The life time and performance have reached the advanced level of foreign countries. At present, the shield sealing produced by our company has been applied to shield machine equipment of host manufacturing unit, construction and maintenance unit. Through extensive use and verification by construction units, favourable comment and economic benefits have been achieved. Domestic shield sealing is gradually replacing foreign products.

With strict enterprise production standards and manufacturing stable and reliable products, the company has passed GB/T19001-2016/ISO 9001-2015 international quality management system standards. We participated in the formulation of Rubber Seal for Full Section Tunneling Machine national standards , which is promulgated and implemented of in September 2018. The company has obtained national patents of “Lip Seal Ring for Large Shield Machine” and other fifteen national patents, such as the patents of Pipe Pressure Test Seal Ring.

The company has won the award of “Shield Machine Main Drive Seal” new product awarded by six ministries , such as Beijing Science and Technology Commission, Development and Reform Commission. China Machinery Engineering Association Driving Machinery Branch has given “High-quality Domestic Accessories Products”. It also won the reputation of “class A supplier” of TIANJIN PIPE (GROUP) CORPORATION.
