Shaker and Hook Screens
Industrial Screen and Maintenance understands the needs of the many industries needing strong and reliable shaker and hook screens for sifting, sieving, and sizing purposes.
Shaker and hook screens are often considered to be the most important of the solid control system when it comes to oil drilling operations. The performance of every piece of equipment that follows depends on the performance of the shaker screen and how effectively it removes solids from treated drilling fluid.
Shaker Screen Types
Some of the types of shaker screens depend both on the structure of the screens themselves, as well as the aperture and design.
Common screen structures include the flat screen design, traditionally the most often used shaker screen type, as well as newer designs such as the pyramid design. The dimension of the pyramid design allows for a significant increase in the fluid handling capacity of each screen – up to 40% greater, to be exact.
Hook Strip Screens
Industrial Screen and Maintenance can create nearly any type of hook strip screen for your sifting, sizing, and straining needs. The hook strip design refers to the way that shaker screens used for sifting, sieving, and classifying needs are secured using rails clamped along the edge to provide tension across the screen surface. These are called either hooks or hook strips.
Single Layer vs Double Layer
Depending on the application, a shaker screen might be single layer or double layer. A single layer hook screen, like its name suggests, features one layer of screen held to the proper tension with banded hook edges that add strength. A double-layer screen can include both a coarse mesh and a fine mesh, increasing strength and lengthening the shaker screen life expectancy.
- Steel – Stainless is the basic alloy of this group and is used extensively in the manufacturing of wire cloth. It contains nominally 18% Chromium and 8% Chromium and 8% Nickel.
- Stainless Steel (Type 304) – Stainless is the basic alloy of this group and is used extensively in the manufacturing of wire cloth. It contains nominally 18% Chromium and 8% Chromium and 8% Nickel.
- Type 316 – with its addition of 2% minimum Molybdenum, it provides considerable increased resistance to certain corrosive media. It also provides increased strength at high temperatures.
- Type 304 L and 316L – are lower in carbon content and are frequently used to retain corrosion resisting properties after welding.
- Type 17-4 – Precipitation Hardening also known as Type 630 is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance. High strength is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius). Primarily used for our Downhole Motor Components, Drilling Screens and Aerospace components.
