Teflon lined with SS304 Braided
With reinforced rib net set of bellows With reinforced rib net set of bellows, reinforced rib is set on the F4 corrugated concave, high negative pressure.
Corrugated pipe connecting a variety of ways. The general availability of flange connection, oil connection, threaded connection, quick joint, and directly connected with a pipe, fixed by the clip or metal wire. No DN4-32mm wave net F4 withhold hose can be produced, our factory can also provide connection mode corresponding to the user's requirements. According to the characteristics of
1 user requirements and joint reasonable selection of fast joint model. (including the work pressure, the connection form of material properties and flow, temperature, corrosive and environmental temperature, and the number of lines etc.)
2 if you need will be connected with the direct and rigid pipe welding should pay attention to the following points: (1) will be inserted inside the rubber sealing ring with special tool to remove the hook, the welded joint is completely cooled, the sealing ring is arranged in the sleeve. (2) if there is no special hook, also can use a damp cloth or cotton yarn with the sleeve inner diameter of the seal ring, to prevent damage to the sealing performance of high temperature welding. (3) the fast not be placed on metal plate and other conductive body, so as to avoid internal short circuit current burned out, affecting sealing performance and fit precision. 3 ball type joint spherical (male connector) and cone (female connector) in the use and transportation should be pay attention to the protection, not to scratch or collision, so as not to affect the connected sealing.

? 4 the correct choice of a quick joint type and reasonable installation, are the two important factors in service life.
