Product Description
Wedge wire well screen pipe large opening area positive type slot water well sand intake screen
There is a lot of sand, gravel, and other substances in the aquifer of the well, these materials will wear equipment and well pumps, causing expensive losses. A water well screen is needed to remove these impurities.
Stainless steel v-wire (wire wrap ) screen pipe is the main screen pipe type used in the water well industry, it is welded together by v-shaped wire and support rod through advanced circular resistance welding. This kind of screen tube has the characteristics of firm structure, large opening area, corrosion resistance, nonblocking, and no maintenance.

Slot size selection: 0.10mm, 0.15mm, 0.20mm, 0.25mm, 0.30mm… (or as your need)
OD: 1” – 34”
Length: Up to 6500mm
Depth & height: As your need.
Open area: Up to 60% (high flow, low-pressure drop)
Installation location: Aquifer
Application: Municipal water source well, Domestic well, Agricultural water well, Groundwater, Industrial water well.The specification of the wire can be customized according to the customer's requirements.
Characteristics of Wedge Wire Well Screen
1.Corrosion-resistant material
Contact with water and the use of anti-corrosion materials can improve the service life of products.
Due to the different use environment, it is necessary to select appropriate raw materials in combination with water quality.
2.No clogging, Easy to clean
Positive type wedge wire screen pipe, The contact surface with water is a smooth filter surface.
There are only two points of contact between impurities and the surface, particles can pass through the screen without being stuck by the screen gap which will not cause a clogged.
Reduce maintenance and replacement cost of products.
3.High strength, sufficient column, and collapse strength.
4.Large opening area, the high filtration area ratio
Continuous slotting structure.
Increase the water flow rate and reduce energy consumption.
The large opening area percent reduces the pressure drop and the speed of water entering the screen, it can make the water flow into the screen slowly so as to avoid sand from entering the screen tube under high pressure and causing abrasion. Prolong the service life of water well.
Strong transmission capacity.
The wedge wire well screen pipe has a solid structure, high porosity, and precise gap size. Particularly suitable for fine sand and silt formations in water wells.
Oil and Gas upstream Well Screen (well screen and casing)
Wedge wire screen pipe + Liner pipe
Application in a deep vertical well, oil dan gas well, and supply well.
The liner provides compressive strength, freeing wedge wire screen pipe, in this way, the width of the wedge wire can be reduced and the area of opening can be increased.
In addition to the overall solution, we can also customize a good screen assembly.

Sand control screens
The appearance of the sand control premium screen provides material conditions for the development of horizontal well and sidetracking well and the oil exploitation of a high sand reservoir.
Oil wells are located in different geological and sand layers, and different steel grades and types of sand control filter pipes are selected.
Function: sand prevention
Product type: V-shaped wire tube.
Advantages: high opening rate, firm structure, not easy to block, high-cost performance.
Application: oil well drilling, natural gas well, water well, brine well, etc.
Main characteristics of petroleum sand control screen
V-wire structure, with self-cleaning function.
High machining accuracy, seam width ≥ 0.15mm, tolerance ± 0.03mm.
The strength is high. There is a 0.1-0.2mm anti-corrosion hardening layer on the surface of the slot cavity, and the strength is more than three times the strength of the base pipe.
The surface of the slot cavity is smooth and the roughness is low, which can reach ra1.6mm.
The oil sand control screen has a good sand control effect and high-cost performance.
Automatic cleaning device for the inner surface of petroleum sand control screen
It is a grinding machine that is penetrated into the petroleum sand control screen pipe and cleaned with the relative movement of the petroleum sand control screen pipe.
A driving mechanism that drives the grinding machine to move back and forth along the length direction of the petroleum sand control screen pipe.
A mandrel connected between a grinder and a driving mechanism.
During the cleaning process of the grinding machine, the inner surface of the oil sand control screen pipe is scoured and the air is dried. High-pressure gas blows the pipe dry at any time to prevent rust.
Surface characteristics of petroleum sand control screen
The two ends of the inner layer pipe are provided with a taper thread, the screen mesh is composed of two layers of inner and outer fine mesh and coarse mesh, and the protective pipe is provided with a longitudinal narrow seam.
The inner layer pipe is surrounded by two layers of screen mesh with coarse and fine mesh, and the joint edge is protruded at the seam of the protective pipe to form the screen joint and the welding fusion joint firmly connected with the protective pipe.
A pipe hoop with a longitudinal long hole is arranged at both ends of the protective pipe.
The petroleum sand control screen pipe has the characteristics of higher filtering precision, high tensile and compressive strength, high-density gap, low flow resistance, low flow resistance, welding technology, high efficiency, low cost, corrosion resistance and wear resistance.
As the inner layer pipe, screen and protecting pipe are welded and consolidated into a whole through joint and pipe hoop, the compressive strength, tensile strength and torsional strength of the screen pipe are greatly improved, and the service life and sand control reliability of the oil sand control screen pipe is increased.
The thread lengthening connection structure makes the oil sand control screen light in weight, convenient and flexible in loading and unloading.
