Wuxi? 70mm ~? 90mm flat metal bellows prestressed plastic pipe

Prestressed Bellows Bellows flat tube is helically wound with a thin strip made of round and flat bellows. Now that more and more use of architectural concrete structure, while the bellows is prestressed post-tensioned concrete structures necessary. Bellows flat circular bellows is in fact based on the machine with the pressure of repression. Implementation of the standards I produced the metal bellows is JC225-2007; the implementation of standards prestressed plastic bellows is JT / T529-2004. They have good versatility, interchangeability, supporting reasonable, easy to use features. Contact: Fei Mobile: 15961509761 Company Website: http: //shixin1.qiyegu.com/ a prestressed metal bellows flat tube 1, the tube characteristic light weight, stiffness, tightness good, strong adhesion pullout. 2, pre-stressed metal bellows Scope: post-tensioned prestressed concrete bridge with metal bellows; reinforced concrete hollow plate board with prestressed metal bellows; bolt holes for metal bellows; architectural, build a wall, base line embedded pipe. 3, prestressed metal bellows Performance A: rigid test: Anti Concentrate Load 0.75KN or uniform load 1.5KN, radial deformation ≤0.1d. B: impermeability test: irrigation water, mud or water-cement ratio of 0.5 30 minutes without leaking, leaking slurry. C: Tensile test: axial tension 5KN wall without damage. D: anti-pull test: the above embedded in concrete pullout resistance of anchor bolt design pullout force of 2.3 times. E: Bending test: 30d degree of bending radii of curvature, no leakage, leakage of slurry. Second, the plastic corrugated pipe flat tube 1, corrugated plastic pipe flat tube using the original raw material granular material. Do not use powdered and recycled granule-like materials. High density polyethylene (HDPE) shall meet the requirements of GB / T11116, and polypropylene (PP) shall meet the requirements of GB / T18742.1 of. 2, plastic bellows should look smooth, uniform color, are permitted inside the compartment rupture, scratches bubbles, cracks, lumps and affect the use. 3, the ring stiffness of corrugated plastic pipe ring stiffness of not less than 6kN / m2 4, partial lateral load corrugated plastic pipe to withstand lateral partial load, the pipe surface shall not crack; 5min after unloading the residual deformation of the pipe must not exceed 10% of the pipe diameter . 5, flexible plastic corrugated pipe bending method prescribed after repeated bending or five times, special plug smoothly from plastic wave tube is passed, the flexible plastic corrugated qualified. 6, low-temperature impact resistance of corrugated plastic pipe drop hammer impact test impact rate vacuum TIR maximum allowable value of 10%. 7, connecting plastic pipe can be used to take a long plastic welding machine plastic pipe are welded or mechanical connection. Mechanical connection in the form of joint conduct, including pipe and tube connecting the connection pipe connecting the head tube and the anchor plate connected to the exhaust pipe connected to the exhaust pipe pipe connector three Yixing City source Mao Bellows Co. The company is the province of professional production and sales of bellows, ordinary galvanized corrugated pipes, metal bellows, corrugated plastic pipe company, the company sells high-quality bellows in full compliance with national standards and engineering requirements, price concessions, welcomed the new and old customers to our company guidance.
