Steel frame
Built from A572 Gr50 and A36 steel. Through every process — laser cutting, saw cutting, drilling, rolling/bending, MIG welding and mechanical assembly — we hold tolerances of ±0.030. Custom frame sizes available.
Specification summary
Replacement Screen Specifications
Whatever the make or model of your shaker, Marshall can supply the screens you need at very competitive prices. Here's how they're built.
Frames
Three frame constructions
Composite frame
A high-strength plastic and glass composite reinforced with high-tensile steel rods. Custom composite frame sizes available.
Polyurethane screen
Provides a ramp that helps maximise screen washing. Long service life and low noise, in a range of sizes.
Screen cloth
What goes into the cloth
Long screen life, high separation efficiency and low cost are the key factors when buying shaker screens.
01Material
Shaker screen cloth is woven from stainless steel wire, grades SS304 to SS316L.
02Layers
Non-layered screens have a single fine-mesh cloth, reinforced by a coarser backing cloth, mounted on a panel. Their openings are regular in size and shape.
Layered screens have two or more fine-mesh cloths, usually of different mesh and reinforced by a coarser backing cloth. Their openings vary greatly in size and shape.
03Cloth type
Several square-mesh weaves are used in oilfield screens, differing in the wire diameter used in their construction:
| Type | Construction | Characteristics |
|---|---|---|
| MG | Market Grade — single layer | Mainly used as a scalping screen |
| TBC | Single layer Tensile Bolting Cloth over a heavy support mesh | Well-defined cut point; poor blinding resistance |
| TRSF / DX | Two superfine layers over a heavy support cloth | Good screen life; good blinding resistance |
| XR | Two oblong-aperture (extended rectangular) layers on a square support mesh | High conductance; long life; good blinding resistance |
04Capacity
Screen capacity — the volume of mud that passes through a screen without flooding — varies widely with shaker model and drilling conditions. Drilling rate, mud type, weight and viscosity, bit type, formation type and screen mesh all affect throughput.
053-D screens
Three-dimensional panels increase usable screen area by corrugating the surface, like a pleated air or oil filter — adding capacity without more shakers.
They work best as the submerged, feed-end screen on linear-motion shakers. Past the fluid end point, a 3-D screen tends to channel drilled solids, so a flat screen at the discharge end eliminates channelling, dries cuttings and reduces fluid loss.
Standardisation
API RP 13C labelling
The API committee on Standardization of Drilling Fluid Materials recommends a standard for labelling shale shaker screen cloth.
The labelling procedure allows a direct comparison of separation potential, the ability to pass fluid through a screen, and the area available for screening. Every API screen label includes:
- 1Manufacturer's designation
- 2Separation potential
- 3Flow capacity
All Marshall screens comply with API RP 13C. See the glossary on the shaker screens overview for terms such as conductance and cut point.
