good quality slotted water well filter screen factory  

 

Casing pipes( Slotted casing pipe ) are used for oil and gas wells. Steel casing pipes and tubing are applied to furnishing and installing cased tunnels, where they indicate to pass other utilities or obstructions without open excavation. Steel casing pipes and tube have smooth wall and a minimum yield strength of 35,000 psi. Corrosion-proofing water-based paint is applied on the outside pipe surface to protect against atmospheric corrosion during transportation and storage.

Advantages

 

 

(1) a wide range: almost any material can be engraving cutting;
(2) safe and reliable: the non-contact processing, will not have mechanical extrusion or mechanical stress on the material.

(3) the processing accuracy of 0.01 mm.

(4) ensure that processing of the batch effect. High and quick speed.
