High temperature pr-tighten belleville spring Model: ASL-620 Features: High temperature pr-tighten belleville spring has superior temperature compensation function, can compensate for thermal expansion and contraction caused by repeated changes so that ensure there is no slack bolts at high temperature and low temperature, then remained the pre-tighten purpose stable, and can effectively absorb mechanical vibrations, avoid loose bolts caused by mechanical vibrations, ensure seal durable and reliable, prevent bolt fatigue and gasket failure. Application: Suitable for all kinds of flange bolt pre-tightening in high temperature. Such as various pipe flange, valves, heat exchanger, reactors, mixer, pumps, centrifuge and others flange bolt pre-tightening. Especially the bolt connection positions of the temperature difference more than 100℃. Specifications: common specifications M8 ~ M72, also can be manufactured according to user requirements. Working temperature: Optional material temperature range is -240 ~ + 750 ℃.

We offer seal gaskets. Modified ptfe corrosion-proof spacer plate model: asl-512 processed deeply by inorganic substance as filling agent which is dissolved into ptfe. Feature: compared with pure ptfe, modified ptfe has many advantage, high compression strength and wear resistance, good thermal conductivity and thermal expansion reduce, etc; the internal multi-directional fiber structure make the product has strong resistance to chemical corrosion, without cold flow and creep phenomenon, that can maintain reliable seal for a long time. with using inorganic filler, the plate does not contain any binder, will not adhesion with the sealing surface, can be used repeatedly in the same seal surface. easy cutting, can be cutted by machine or by hand, easy to install there is no aging problem, can be long-term preservation. Application suitable for sealing of the pipeline and equipment in chemical, pump, the paper making, oxygen manufacturing, power generation and other industry.
