Stainless steel woven mesh plays a critical role in the petrochemical industry, particularly in sand control screens. These screens are essential for downhole sand control, preventing the migration of sand particles while allowing the passage of fluids during well clean-up, production, and stimulation activities. A high-quality stainless steel woven mesh is vital for ensuring raw material alloy content, mesh micron accuracy, and eliminating issues like broken or double wires.

Types of Sand Control Screens：

Sand control screens are integral to most downhole sand control strategies, each designed for specific applications:

Pre-Pack Screens：These screens are pre-packed with gravel and used to prevent sand migration during well production. They offer efficient sand retention and are commonly used in wells with high sand production potential.

Shrouded Metal Mesh Screens：These screens feature a metal mesh wrapped around a base pipe, providing enhanced durability and resistance to wear. They are suitable for high-pressure applications and environments with aggressive well conditions.

Expandable Screens：Expandable screens can be deployed in smaller diameters and expanded once inside the well to fit the casing perfectly. They are ideal for wells with variable or uncertain conditions, providing a secure fit and effective sand control.

Commonly used products include Wire Wrap Screens, Pre-Pack Screens, and Metal Mesh Screens. If customers have customized requirements, custom solutions can be performed.

Sand Screen Mesh Evolution and Features

• Developed in the 1980s: Stainless steel woven mesh for sand control screens consists of a base pipe, filtration jacket, and outer shroud, minimizing installation damage. Its corrosion resistance ensures durability in harsh downhole conditions. Special welding techniques replace costly sintering, while double-layer media and uniform pore sizes enhance filtration performance.

• Sintered Stainless Steel Mesh (Introduced in the 1990s): It consists of a base pipe, multi-layer sintered metal mesh, and outer shroud. It offers similar damage resistance and corrosion protection as non-sintered versions, with high pore size accuracy capable of controlling 100μm diameter sand particles.

  Till now ,we manufactured and supplied mesh roll as majority items for this sand screen ,Square Plain and single layer Dutch weave is well developed.
