High strength through resistance to twisting, compressive, and tensile forces.
A smooth bore that does not impede the passage of probes, tools, etc.
The special bridge slot of screens helps improving their mechanic strength.
Usually the length of bridge type water well screen slotted pipe is 3.1m, and our engineer also can design the products and supply the best solution as per the clients' special requirements.
Bridge type water well screen slotted pipe can increase its flow to three to nine times, when compared with other kinds of screens.
The sand and gravel can't easily block the slot because of bridge slotted screen's special bridge slot design. Bridge type water well screen slotted pipe has great mechanical strength and water entering capacity.
Meanwhile, bridge type water well screen slotted pipes use steel punching technology and rolled in many ways, so bridge slotted screen is light, cheap and easily operating.
We use Computerized Numerical Control to punch the productive process, so the slot size can be changed as your requirements.
In order to give customers more convenience, we can offer any diameter bridge type water well screen slotted pipe, we also offer galvanized bridge slotted screen pipes to prolong the operational life.
We have manufactured bridge type water well slottted pipes for several years and we are famous for our profession.
We also can produce bridge slotted screen along with ISO9001 standard, welcome all the buyers and distributors cooperate with us home and abroad.
