复合管与风管(国外英文资料) Inspecting controlling structure The product is made of seamless steel tube, welded steel tube, and the inner wall is coated with high adhesion, anti-corrosion, food-grade polyethylene powder coating or epoxy resin coating. It is the advanced product of traditional galvanized pipe, which is made from pre-processing, preheating, internal painting, flowing and reprocessing technology. Classification and advantages Inspecting controlling there are many kinds of classification, according to the structure of pipe material classified as: steel belt enhance gangsu composite tube, seamless steel tube enhance inspecting controlling, gangsu composite tube and wire mesh mesh steel skeleton inspecting controlling. At present, the most popular in the market is steel belt reinforced steel composite pipe, which is our steel plastic composite pipe structure As gangsu composite pressure vessel, this kind of pipe by the middle tier for high carbon steel with curly forming butt welding of steel belt layer, inner and outer layer of high density polyethylene (HDPE). This pipe layer for steel strip, pipe pressure performance is very good, so different from aluminum belt, pressure is not high, pipe maximum diameter can do 63 mm, gangsu tube of the largest diameter can do 200 mm, and even more; Due to pipe the middle layer of steel belt is closed, so the oxygen resistance effects of steel-plastic tube at the same time, can be directly used for direct drinking water project, and its outer layer is plastic material, has the very good corrosion resistance. So good performance that inspecting controlling has a very wide range of USES, oil, natural gas transportation, industrial and mining pipe, drinking water pipe, drainage pipe and so on all sorts of fields all can see the figure of the tube. The connection form The steel plastic composite pipe under the normal DN50 is threaded, and the use of grooved card coupling or flange connection is used in DN65 and above. The design als
