Fire pipe fire pipe sales _ _ Weifang Shaanxi Delong machinery

 Fire tube includes two categories of products: ① of the connecting pipe sealing rigid joints, flexible couplings, grooved mechanical tee and flange; ② role in the transition of the connecting pipe elbow, three, four reducers, blind panels. ③ the connecting seal groove connection fittings has three main parts: sealing rubber ring, clamp and locking bolts. Fire tube after installation requires backfilling fire tube price, quality backfill will affect the performance of the pipe in when backfill attention to the following points: First, grasp backfill opportunity after pipe installed to immediately backfill, can not stay too long . Second, select backfill material backfill material to select high-quality gravel and sand. Third, consider the impact of stratified backfill pipe trench on the road, at the bottom of the tube to the pipe backfill on top and above part stratified backfill, backfill material for strict control of trench fire tube, then tamp the backfill. Fire drainage pipe, which is common for intubation and the series of cast iron drainage pipe, pipe fittings such strong earthquake fire tube sales, uses rubber ring seal, and the use of bolts. Fire Fire Water pipe fittings, mostly made of cast iron, with a mild high, thin wall, pressure, impact resistance and seismic performance advantage and so on. The tubes are used in the interface flexible interface, but also has a certain elongation and the deflection angle. Fire hose clamp member benefits 1. Easy; clamp flange lighter than the locking ingenious mechanical design. No need for holes to lock. 2. Fast; clamps without welding and re-galvanized. 3. Reliable; its large pipe end tensile strength, thermal expansion pipe 4 isolation shock absorbers also be affected;. ① end of the tube because there is a gap to be effective in blocking the spread of noise and vibration. ② gasket also absorb noise and vibration fire tube Sales fire tube _ _ Shaanxi Delong machinery provided by the Weifang Weifang Delong Machinery Co.
