pultrusion machine

Patentpultrusion machine manufactured by Jinzhou Sihai company, include different kinds of products ,20T1.2X0.620T1.2X0.3 8T4.2X0.3 etc, which can manufacture transparent tile and large hollow special profiles . The invention has following advantages: 1. Generally the lengthways strength is 200% of ordinary wound Conduit, be free from any condition. 2. This kind of technics has same inside and outside diameter. 3. Can infinite extension, and cut down cost to reduce the connector. 4. Mean while it has the function of general FRP Conduit, light weight and strong, the weight is 1/4 of steel, 1/8 of concrete, one person can move, and convenience transport, simple construction, the strength equal with steel pipe. 5. Smooth inside wall, small friction coefficient, so penetrate through slippery, don’t damage cable. 6. Non-magnetism, no electric corrosion, being applicable to Single-core Cable, but the steel Conduit is the magnetism material, have to be use after special processing. 7. Insulate, resistance to chemical corrosion, not rusty, service life above 50 years. 8. Having Heat-proof, fire resistance, and big ampacity, can working at 130°C,better than PVC Conduit. 9. Resistant to cold condition, the strength that under the low temperature will be higher than in high temperature, but the PVE-U Conduit will be have fragile phenomenon under cold circumstance. 10. Cood Water Resistance, can be use in damply or water environment for a long time, superior than abio-FRP Conduit. 11. Simply installation, lower cost, can resolve the problem that long time to constrution and influence the city transportation etc. can carry out construction at nighttime, return to fill the road surface. 12. The Conduit adopt Holding-inserting connecting method, convenient installtion, in order to accommodate thermal expansion and contraction, we add rubber seal ring at contact place as well as prevent mud and water run into the Conduit. 13. The lower comprehensive investment, quickly finish, make a tremendous social and economic benefit.
