Bridge Slot Screen, 1.ISO, 2.K55,J55,N80,L80 or others, 3.API 5CT standard, 4.STC,LTC,BTC thread or others - details see: https://www.machineto.com/2013-carbon-steel-bridge-slot-screen-for-drilling-well-factory-10218640

Product name : Bridge Slot Screen

Bridge Slot screens are used for oil and water exploiting.

Characteristics:Its a type of well screen with vertical slots that are formed by protruding "bridges”that are pushed outward from the well casing.

The sand and gravel can not easily block the slot because of the special bridge design.It has great mechanical strength and water entering capacity.Meanwhile,it use steel punching technology and rolled in many ways,so it is light,cheap and easily operating.

We use CNC to punch,so the slot can change as your requirements.In order to give customers more convenience,we can offer any diameter screens.We also offer galvanized ones to prolong the operational life.

Materials: 304 302 304L 316 316L stainless steel and low carbon , can be made according to the customers requirement.

Wall thickness:4-8mm,

out diameter:146-529mm

standard length:1-6meters

supply capacity:6800meters per month

Advantage :

High strength through resistence to twisting, compressive, and tensile forces.

A smooth bore that does not impede the passage of probes, tools, etc.

The special structure of the slot makes it difficult for particles to get stuck in the slot, Thus bettering its discharge capacity.

The special bridge slot of screens help impoving their mechnic strength.

Application of Anticorrosive coasting will prolong the span life of wells.

Slots and the diameter of bridge slot screens can be custom made to satisfy your needs.

Conventient to operate owing to various connecting methods between screens.

Lighter in weight and lower in price.
