Steel mesh skeleton tube wholesale | Shandong steel mesh skeleton pipe supplier - WANJI skeleton tube Features: Good (1) creep resistance, high mechanical strength, durable plastic creep due to occur under normal temperature and stress, lasting at higher stress occurs under the action of brittle fracture, so the promise of pure plastic pipe stress and pressure capacity is very low (typically less than 1.0Mpa). The mechanical strength of steel is about 10 times to about thermoplastics, and in the plastic temperature range is very stable creep does not occur. After the wire mesh frame and plastic composite, steel mesh skeleton can be effectively constrained plastic creep rupture strength of the plastic itself is also greatly improved. Therefore, steel mesh skeleton of polyethylene pipe allowable stress than doubling plastic pipe. Strength (2) good heat resistance of plastic pipe in its operating temperature range is generally decreases with temperature increase, the temperature is 10 ℃ increase its strength was reduced by approximately 10%. As the steel mesh skeleton polyethylene pipe about 2/3 strength is borne by the steel mesh skeleton, so its strength with increasing temperature while using less than minimize any kind of pure plastic pipe. Experimental results show that each increase of 10 ℃, steel mesh skeleton polyethylene pipe strength decreased below 5%. (3) rigid, impact resistance, good dimensional stability, but also moderately flexible, elastic modulus, hardness and softness of steel is usually about 200 times higher density polyethylene elastic modulus, due to strengthening of the role of the steel skeleton of steel wire mesh skeleton of polyethylene pipe rigidity, impact resistance and dimensional stability is better than any kind of pure plastic pipe. At the same time due to the steel mesh skeleton itself is a flexible structure, so that the composite tube in the axial direction has a certain flexibility. So the pipe has just, soft binding characteristics, in terms of reliability and handling, transportation, installation and operation of both adaptability outstanding performance. Ground mount installation can save the number of low cost; underground installation can effectively withstand the sudden shock loads due to subsidence, slippage caused by vehicles. Small diameter pipe may be appropriate to bend over undulating terrain arrangement or serpentine layout, saving fittings. (4) Due to the thermal expansion coefficient of linear thermal expansion coefficient of plastic pipe steel for 10.6 ~ 12.2 × 10-6 (1 / ℃), pure plastic pipe linear expansion coefficient of 170 × 10-6 (1 / ℃), steel mesh skeleton polyethylene composite pipe under the constraints of steel mesh skeleton composite pipe thermal expansion is greatly improved, lower than any conventional plastic pipe, through testing, steel mesh skeleton of polyethylene pipeline expansion coefficient of 35.4 ~ 35.9 × 10-6 ( 1 / ℃), only ordinary carbon steel pipe 3 to 3.4 times. Experimental results show that underground installation is generally no need for thermal compensation device, pipe laying can play a serpentine-shaped absorption (or release) the effect, so that the installation costs. (5) does not happen quickly crack under pure plastic pipe particularly large diameter plastic pipe at low temperature pure hoop stress lasting effect, easy to produce rapid crack by local defects, stress concentration caused by (a few hundred meters to kilometers above moment ), so the current international resistance to rapid crack plastic pipe made high performance requirements, and low-carbon steel brittle fracture problem does not exist, there is a steel net to make plastic deformation and stress are not reached to produce rapid crack The critical point. So theoretically steel mesh skeleton polyethylene pipe does not exist to rapid crack. (6) steel, plastic two-plastic composite materials uniformly reliable on the market at present due to the composite surface steel composite pipe, plastic is the interface between the continuous rule, long-term use of alternating stress the role of easy delamination, causing the connection leaks, internal bottlenecks like contraction, clogging and failure. Compared with its steel mesh skeleton polyethylene pipe is hot melt through a dedicated network structure (modified HDPE) plastic and steel mesh closely integrated and seamless. Both materials mutually binding of the uniform, the stress concentration is small. Kyrgyzstan Plastic Co., Ltd. Shandong million (www.shandongwanji.com) is a set of PE plastic product development, production, marketing, construction, services in one integrated enterprise. With abundant capital, advanced technology and equipment and strong management team came from behind to become one of the largest northern pipe fittings manufacturer, to provide users with product selection, design, supply, installation and after-sales service one-stop support services. Founded in May 2010, is located in Zibo City Huantai Dongyue Industrial Park, 3 km from the city, south of Shandong Dongyue Group, horse riding north Lake Wetland Park, geographical location and convenient transportation. Companies registered capital of 100 million yuan, the total investment of 240 million yuan, 120 million yuan investment in fixed assets, covers an area of ??100,000, with a total construction area of ??56000㎡. Of which 40,000 square meters of production workshop, raw materials, finished products of 10,000 square meters, assisted living facilities of 6,000 square meters, the annual production capacity of 50,000 tons. Company organization for integrated management, sales and marketing, quality and technology department, plans to supply the Ministry of Finance and the Ministry of six departments of production. Existing staff 290 people, professional and technical staff of 55 people, senior engineer 7 people. The company set production, marketing, and research and engineering services in one, to provide users with product selection, design, supply, installation and after-sales service, such as a one-stop support services.
