2.地热井的水过滤管

地热井滤管管由API标准的基本管和高精度的线绕线滤波管组成.
Жичана цев за филтер за воду се прави заваривањем жице за намотавање клина и клинасте шипке:
　　1.It has strong pressure bearing capacity.With the support of the inner-layer base pipe,even if external filter pipe is deformed partially,the gap will not increase,and sand control performance will be more reliable.It is fit for a harsh service environment.
　　2.The gap of the outer-layer screening pipe is uniform,the error is as small as 0.05mm,which can control sand effectively.
　　3.Gap density of the screening pipe is better than other screening pipes,which reduces the flow resistance and greatly improves the water yield.
　　4.Continuous V-shaped structure reduces the water penetration speed and alleviates the pressure on the pipe body and the equipment.
　　5.Pipe diameter is smaller,这减少了钻井施工的困难.
　　6.Materials of the base pipe is J55, K55, N80,etc of API standard,those of the outer-layer screening pipe is304stainless steel or high quality low carbon steel,and other materials can also be used in accordance with the customer’s requirements as well.

3.Water filter pipe of air-conditioning well

The water filter pipe for air conditioning produced by our company is specially designed for water source heat pump system.It is used for water intake and recharge of water source heat pump well.This product has the following characteristics:
　　1.High porosity.该产品的孔隙率结束了25%.High porosity can reduce water flow penetration speed,reduce the flow resistance,not only improves the effect of water intake and recharge,but also saves the energy consumption of water pumping and recharge.
　　2.The gap is not be easily blocked.The gap structure is narrow outside and wide inside,and the gap will not be blocked by sand and stone,which prolongs the service life of the air conditioning well.
　　3.The pressure-bearing capacity of the pipe body is big.该产品的表面没有焊接.Compared with other welded pipes,it has a higher ability to bear pressure.
　　4.Sand control effect is good.The gap control of this product is accurate,the error is small,外层滤波器和砂颗粒可以有效地防止到井中,并且可以减少水泵设备的损失.
　　5.Convenient for construction.与桥管和水泥管相比,this product is light in quality,convenient for being put into the well and the risk and other unsafe factors brought by construction can be reduced.
　　6.Diversified materials.The pipe body is made of galvanized carbon steel,plastic sprayed carbon steel and stainless steel.Excellent material makes the pipe and filter material never stick with each other,which effectively ensure long-term permeability.

Napomena:The above is the common specification,we can design for outer diameter,根据客户要求满足客户使用需求的差距和孔隙率.
