FRP process pipeline 

 Long Kang FRP process pipe is mainly used for the petroleum, chemical, electric power, metallurgy, medicine and other fields, with a light weight, high strength, strong corrosion resistance, installation, easy maintenance, etc.. It with the glass pipe the same as with other types of pipe fittings of incomparable features. 

 Characteristics of the FRP process pipe 
 , FRP process pipe has excellent physical properties, the proportion of glass fiber reinforced plastic pipe 1.8-2.1, about 1/4 of steel, high specific strength than steel, cast iron and plastic, glass pipe, the weight does not exceed the same specifications of steel pipe 1/3 of the excellent physical and mechanical properties, in addition, roughly the same expansion coefficient of glass pipe and steel, the thermal conductivity of only 0.5% of the steel is a good insulator of heat and electricity. 
 2, glass, steel process piping resistance to chemical corrosion, long life, suitable for delivery of the different media of various acids, alkalis, salts and organic solvents. 
 3, excellent mechanical properties of fiberglass parts water, hydraulic characteristics is an important feature of glass pipe. Excellent hydraulic characteristics means that the fluid pressure head loss, you can use smaller diameter or smaller pump power, thus reducing the initial investment of the pipeline project to save energy, reduce operating costs. Fiberglass surface is quite smooth, generally rough surface is desirable 0.008, almost hydraulics smooth tube in the operation, the inner surface of the steel pipe, cast iron pipes, cement pipes, etc., the frequent occurrence of localized corrosion, becoming more and more rough FRP always maintained a newborn control smooth surface state. 
 4 and FRP process pipe installation, low maintenance costs, In general, the glass pipe does not require special corrosion treatment; insulation layer can be thinned, not even do another thermal insulation; pipeline is relatively light, lifting equipment, small tonnage, low power consumption, glass pipe length than cement pipes and cast iron pipe length, the connector is relatively reduced, which will reduce installation and maintenance costs, which has been a lot of engineering practice at home and abroad proved. 
 5, glass and steel process piping design flexibility modified cycle is short. FRP will dip of resin matrix fiber reinforcement layer winding in accordance with the specific process conditions and proper curing is made on the mandrel, the wall is a layered structure, by changing the resin system or using different reinforcements to adjust the physical and chemical properties of the glass pipe, made to adapt to different media and working conditions of different pressure levels or with a special performance of FRP pipe. Remodeling cycle is short, is a notable feature of filament-wound composite isotropic metal pipe can not be compared. 
 Two, the application of FRP process pipe 
 ◆ chemical media pipeline 
 ◆ various process tube (chemical process, the papermaking process, the sewage treatment process, the process of desalination, food and beverage processing, pharmaceutical technology, etc.) 
 ◆ small hydropower stations on the pressure in the ground water pipes, power plants, water loop 
 ◆ sewage collection and pipeline 
 ◆ drinking water transmission trunk pipeline and distribution mains 
 ◆ oilfield water injection and crude oil pipeline 
 ◆ heat pipes, seawater pipeline 
 ◆ agricultural irrigation pipe 
 ◆ vacuum tube, the external pressure tube and siphon
