Metal spiral wound gasket sealing element is an Metal Jacketed Gaskets important, is the pressure pipe, valves and other key components of static sealing equipment. Therefore, selection and use of high-quality metal spiral wound gasket products, reduce and eliminate run, run, drip, leak, ensure the safety of the host device, pressure pipes running normally, has very important significance. Therefore, a good metal spiral wound gasket is very important when choosing a job.
A metal spiral wound gasket installation
1, check carefully before installation flange, bolts, nuts and washers quality, carefully check the flanged or interface installation, with or without partial mouth, wrong mouth, mouth, wrong holes and other defects.
2, the metal spiral wound gasket can not be installed side, should ensure uniform pressure.
3, flange sealing parts or surfaces must be clean, gasket surfaces and bolt threads do not allow adhesion of mechanical impurities.
4, should be firmly and evenly tighten the nut, the bolt should be symmetrical and uniformly tightened 2 to 3 times the metal spiral wound gasket pressure evenly.
Second, the metal spiral wound gasket optional
1, according to the working conditions, flange sealing surface type selected metal spiral wound gasket.
2, the compression rate, rebound rate and gasket sealing performance is an important performance indicators, in general, to meet the requirements under the premise compression ratio, the higher the better rebound rate; while in spring rate to meet the requirements of the standard premise, the compression ratio test value is Spiral Wound Gaskets bigger is better. Should choose a good sealing performance, moderate compression ratio and spring rate as large as possible gasket products.
3, the metal spiral wound gasket sealing surface of the body allowed to affect the performance of the scars, voids, uneven and pitting defects. Spiral wound gasket with metallic surface of the body should be uniform, appropriate higher metal band, the interlayer texture should be clear, but not revealing metal band. Metal spiral wound gasket pad spacing should be uniform, there should be no lack of fusion or excessive melting and other defects. Reinforcement ring surface should not have glitches, rugged, rust and other defects, metal spiral wound gasket sealing surface and the upper and lower body reinforcement ring spacing should be equal to the upper and lower surfaces of the inner reinforcement ring with metal spiral wound gasket should be tightly secured intersubjectivity, not loose; outer reinforcing ring and gasket between the body should maintain proper positioning and loose.
4, the selection of quality management system is sound and effective operation of the company's products, the best choice holds special equipment (pressure piping components) manufacturing license and valid type test reports of enterprises spiral wound gasket.
5, the gasket sealing surface of the body allowed to affect the performance of the scars, voids, uneven and pitting defects.
6, the compression rate, rebound rate and gasket sealing Reinforced Graphite Gasket performance is an important performance indicators, in general, to meet the requirements under the premise compression ratio, the higher the better rebound rate; while in spring rate to meet the requirements of the standard premise, the compression ratio test value is bigger is better. Should choose a good sealing performance, moderate compression ratio and spring rate as large as possible products.
Hi,
回复删除Some gaskets are made up of metal gasket material sheet and will require some seating place so that the sealing takes place. Due to the elastic nature of the metal the locking can be done in a proper manner. Now several hybrid materials are available in the market which is used for making gaskets.
Thanks!
