Pipe-based water well screens combine the hydraulic efficiency of wire-wound screens with the great strength of pipe.The base pipe is perforated or slotted API casing pipe,the base pipe can be stainless steel or carbon steel API 5CT casing.The all-welded wedge wire screens are welded together with base pipe by supporting rod.
The Johnson pipe based screen is recommended when high collapse resistance is required and when the screens’ length generates a high longitudinal constraint. The pipe strength allows smaller wrap wires to be used, yielding greater open area.
Features Materials and Anticorrosion Ability.
1. For common wells, the base pipe is API casing or tubing (J55, N80, L80,etc.). Sand control filtration jacket and protective shroud are made of high quality stainless steel.
2. For special wells in H2S, CO2 or C1 corrosive environment, the base pipe is anticorrosion casing or tubing, even is stainless steel tubing. Sand control filtration jacket and protective shroud are made of high quality stainless steel.
3. Have anti-corrosion ability to acid, alkali, or salts.
