In order to improve the quality of spiral wound gaskets, our company purchased a new equipment: laser cutting machine, which is used to produce the inner and outer rings of spiral wound gaskets. The cut seams of the inner and outer rings are smooth and beautiful, and the surface is very smooth.
Metal spiral wound gaskets usually use high-quality SUS304, SUS316 ("V" or "W" shape) and other stainless steel winding tapes alternate with graphite, PTFE, asbestos, non-asbestos, mica, ceramics, vermiculite and other soft materials. It is formed by overlapping spiral winding. The metal band is fixed by spot welding at the beginning and the end. The metal wound gasket with inner and outer rings is especially suitable for occasions where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration .
