High iron hollow board mandrel celebrate the 18 large

Hollow plate mandrel regular size offer; dn300mm * 6m each unit price 620 yuan, dn200mm * 20m unit price of 1,520 yuan, dn200mm * 25m unit price of 1,900 yuan, dn260mm * 10.5m unit price of 950 yuan, dn220 * 8.5m unit price of 650 yuan, dn390mm * 13.5 m unit price of 1,820 yuan, the offer for the manufacturers of the ex-factory price, not include shipping and taxes. commonly circular hollow plate mandrel quote, please telephone counseling 13,373,489,002 hollow plate mandrel use detailed product dimensions offer; (1) in its in place, open the inlet valve, inflatable air compressor. inflated with a pressure gauge control monitoring air pressure, the hollow board mandrel inflation pressure, depending on the model given when the pressure reached the pressure, the valve closes to stop inflation. ( 2) Note shall not exceed the pressure when inflated. (3) used for the first time before the examination inflated determination of sufficient time in each set to achieve the use of pressure, according to the initial setting time of concrete to determine the required number of air compressor to ensure plate girder vertical ribs and upper concrete began pouring in the lower part of the concrete before the initial setting, to avoid construction joints, thus ensuring the integrity of each piece of plate girder concrete field testing, with 6m3/min air compressor inflatable mandrel, each hollow board inflation time 15 ~ 20min, takes less time, less impact on the formation of concrete construction joints the modern hollow plate mandrel the hot vulcanization technology, make up the cold bonding process when heated artesian open plastic defects. hollow the board core mold of the rubber using two layers of natural rubber and layer 12MPA, anti-Rab the hot rolled vulcanization step molding made, in the production process, the interior of the core die of each of the hollow plate tailoring plurality of reinforcement to ensure forming accurate dimensions, anti distorted deformation .2012 exclusively for the China Railway 15th Bureau of the hollow the board core model No.: circular hollow plate core a mold dn300mm * 6m dn200mm * 20m dn200mm * 25m, the octagonal hollow plate mandrel 760mm * 710mm * 21m, 550mm * 360mm * 11m oval hollow plate mandrel 260mm * 390mm * 11m, 260mm * 410mm * 10.5m, 240mm * 410mm * 10.5m etc.. manufacturing hollow component in the construction of bridges, culverts and other needs, the internal model placed in a rebar cage, start using the pump according to a predetermined inflation pressure value inflatable inflated having sufficient strength to withstand the pressure of the concrete (30cm concrete can withstand pressure), pouring concrete, until the initial setting of concrete (with a finger under concrete, finger fingerprints fuzzy), open the three-way valve balloon mold deflated air bag and can be extracted from the cavity within the mold. hollow plate mandrel bridge construction site construction and light provide the necessary conditions. Qingdao high-speed rail hollow plate mandrel Bridge Parts Co., Ltd. to produce easy-to-use, economical and durable, non-carbonated soft contraction any folding. curl, inflated with enough intensity to withstand the pressure of the concrete. operate provincial save labor time and effort, any traditional template can not be done. numerous the bridge rail tunnel. culverts construction engineering. the hollow board mandrel Qingdao high-speed rail bridges Parts Co., Ltd. production, products made of vulcanized rubber and fiber reinforced layer , has a high tensile strength, elasticity and air tightness, filled with compressed air, instead of the original wooden mold bamboo mold. the hollow board mandrel steel mold our production can be repeatedly used, is a the concrete products complementary products to reduce costs and speed up the construction progress
