With perfect quality guarantee system, we can make sure supply timely.Product IntroductionFilter pipe which is also called strainer pipe and screen pipe, in terms of material, can be divided into stainless steel, galvanized carbon steel and other metal or plastic painted; from craftsmanship process, the filter pipes are with wire wrapped, hole punching and laser punching and so on.Strainer pipe is always be considered as the heart of well casing. Usually it is produced by wire wrapped hole punching cast-iron pipe in water supply industry of China which comes to be easily corroded or blocked by chemical, electrochemical and bacteria corrosion. So the efficiency and service life of well will be reduced, especially when ground water with strong corrosive and a lot of sand permeate into the well. On the occasion, water pump will be silted and burn out. To solve this problem, our products adopt high technology with features such as high water capacity, light weight form of structure and widely range of application. Advantages of stainless steel metal filter tube(after comparison in experiment, economic and technical)1, solve the problems of wire rapped filter tube, such as easy to be corroded and blocked, and increase service life of filter tube and well(average life time is 30 years).2, good water permeability, reducing water sediment concentration and extending the service life of pump.3, light tube structure make it possible speeding up completed advance rate, saving at least 3/4 pipe laying time and reducing manual labor intensity.4, there are no waste water and waste gas in the manufacture period, beneficial to environment protection.Product UsageOur products are widely used in industries including water well, oil well, gas well, food processing, manufacturing and chemical industry.
