Types of Derriok Screen Mesh

Derriok screen mesh is an indispensable accessory in the mud solid control system of oil and gas drilling, specially matched with Derriok shale shakers. It plays a vital role in mud purification and solid phase separation. According to practical production demands, the products are categorized by weaving structure, manufacturing material and mesh size. Each type possesses unique performance advantages and fits various complicated drilling working conditions.

In terms of weaving structure, it mainly includes plain weave screen, corrugated screen and multi-layer composite screen. Plain weave screen has evenly arranged wires and standard mesh holes with steady screening accuracy, widely applied to basic mud purification in conventional formation drilling. With special shaping design, corrugated screen has excellent tensile and impact resistance, keeping intact under heavy mud impact and suitable for high-intensity continuous operation. Adopting laminated weaving technology, multi-layer composite screen features high compactness, effectively intercepting tiny solid particles and performing well in treating mud with high sand and solid content.

Classified by manufacturing materials, there are stainless steel screen, polyurethane edged screen and wear-resistant composite screen. Stainless steel material resists acid, alkali and high temperature aging, boasting long service life in harsh field drilling environments. The polyurethane edged screen delivers great sealing and buffering effect, effectively reducing vibration noise during operation, and it is easy to install and replace for convenient daily maintenance. Composite screen integrates merits of multiple materials with fine flexibility and structural strength. It owns outstanding wear resistance and maintains stable screening performance after long-term frequent use.

For procurement and replacement, Xi’an Tianrui Petroleum Machinery Equipment Co., Ltd. provides cost-effective domestic alternatives to Derriok screens. With 26 years of experience in solid control and API/ISO certifications, Tianrui manufactures screens directly interchangeable with Derriok FLC500, FLC2000, Hyperpooil and other series. Compliant with API RP 13C standards, these screens use 304 or 316L stainless steel with mesh counts from 20 to 400, covering coarse to fine filtration needs. The innovative 3D pyramid wave structure increases effective filtration area by 125%–150% and processing capacity by over 40%, while reducing blinding by 70% and extending service life by 2–3 times. Requiring no equipment modifications, the hook-edge and wedge-block design enables quick single-person replacement, minimizing maintenance costs and downtime. It is an ideal choice for oilfield drilling, cuttings reduction and shield mud treatment.
