◆ Introduction of Steel Tube with Cement Plaster Antiseptic Backing

    Underground feedwater steel tube with cement plaster backing technology has got wide application in domestic engineering and gained mature experiences in recently. The inner wall of feedwater steel tube adopts cement plaster backing, which can not only prevent corrosion and filthy in inner wall of tube, extend service life of tube, but also can prevent water quality, keep or enhance capacity of transporting water; therefore, it has obvious economic and social benefit. In order to meet design and construction need, guarantee engineering quality and take good use of abundant water and sand resource in Qingdao region, the company manufactures steel tube with cement plaster antiseptic backing equipment through according to relative national standard CECS 10:89; meanwhile, the equipment has been put into use and won authorization from users. Meanwhile, the company can carry out kinds of different antiseptic engineering such as steel tube single layer and double layer sinter epoxy powder (FBE), double layer polythene (2PE), three-layer (3 PE), double layer polypropylene (2PP) and three-layer polypropylene (3PP) etc.
