Stainless steel bellows valve

This series of valves is specifically designed for the transmission and control of high-purity gases and corrosive, flammable, toxic media, as well as for use under high vacuum conditions. It has been widely used in industries such as electronics, petroleum, chemical engineering, and scientific research.

The upper and lower ends of the metal ripple are welded together with the regulating system, forming a metal barrier between the transmission medium and the atmosphere, ensuring that the valve is applied in some demanding fields without leakage. This design replaces the traditional cylindrical rotating seal of the valve stem with a flat static seal, making the airtightness of the valve stem more reliable during rotation.

The gas leakage rate of this series of valves is less than 2 × 10-7 Pa L/s, operating temperature is -100 ℃ -200 ℃, maximum operating pressure is 1.0Mpa.

Electropolished stainless steel tube

With the continuous development of science and technology, high-tech industries have put forward high requirements for pipeline systems that transmit high-purity gases and clean fluids. In order to solve the pollution caused by defects on the inner wall of pipelines and impurities attached to the system, we successfully developed the internal and external electropolishing technology for stainless steel pipes in 1986, which has been widely used in production sectors such as electronics, optical fibers, atomic energy, pharmaceuticals, blood products, and biotechnology.

characteristic:

After electric polishing treatment, the surface roughness of the pipe wall can reach Ra ≤ 0.1, which not only removes the dirt and oxide layer on the metal surface, but also makes the surface smooth and shiny to the mirror level, thus avoiding the adsorption and retention of the medium during transmission, forming impurities and "heat sources". The polished pipeline was carefully cleaned, and the entire packaging process was carried out in a dust-free working environment to avoid potential secondary pollution caused by subsequent work.

Technical indicators:
