High-Grade NBR Drill String Scraper with 10,000 psi Pressure Rating for OBM and

Our OBM WBM industrial drill string scrapers are high-performance 9" wipers specifically engineered for the demanding environments of modern oil rigs. These versatile drilling mud wipers provide an exceptional seal around the drill pipe, effectively removing both water-based and oil-based fluids during tripping operations. Manufactured from advanced elastomeric compounds, these industrial-grade scrapers offer superior resistance to abrasion and chemical degradation, ensuring long-lasting durability in aggressive wellbore conditions. By keeping the rig floor dry and reducing mud spillage, they significantly enhance operational safety and fluid recovery efficiency. Whether utilized in onshore or offshore drilling projects, our precision-engineered wipers protect downstream equipment from debris and corrosive additives. Trust our professional sealing solutions to maintain a clean, productive, and secure workspace throughout your drilling cycle.

Fluid Versatility: Fully compatible with both Oil-Based Mud (OBM) and Water-Based Mud (WBM) without swelling or material degradation.

High Abrasion Resistance: Constructed from reinforced elastomers to withstand intense friction against tool joints and sharp rock cuttings.

360-Degree Wiping Action: Precision-molded inner lip ensures a tight, uniform seal around the drill string for maximum mud recovery.

Thermal Resilience: Maintains flexibility and structural integrity in the extreme temperature ranges found on global drilling platforms.

Available types of Swab cups:

More corner view for the rubber parts:

Q1: Is this 9" wiper safe for high-concentration oil-based mud (OBM)?
A1: Yes, our wipers are made from specialty elastomers that are specifically tested to resist swelling and softening in aggressive OBM and synthetic fluids.

Q2: Can we customize the inner diameter for our specific drill pipe size?
A2: Absolutely. As a direct manufacturer, we can mold or custom-cut the inner diameter to match any pipe or tubing dimension your project requires.

Q3: How does this scraper improve rig safety during operations?
A3: By efficiently scraping mud off the pipe during retrieval, it keeps the rotary table and floor dry, preventing dangerous slip hazards for rig workers.

Q4: Can our company logo and part numbers be laser-etched on the product?
A4: Yes, we provide permanent laser marking for logos and part numbers, ensuring professional branding and asset traceability in the field.

Q5: What packaging options do you offer for offshore logistics?
A5: We offer moisture-proof, vacuum-sealed individual bags followed by reinforced export crates to ensure the wipers arrive in perfect condition.

Q6: What is the maximum temperature rating for the HNBR version?
A6: Our premium HNBR wipers can reliably operate in environments up to 150°C (302°F) while maintaining excellent mechanical properties.

Q7: Are these wipers resistant to H2S (Sour Gas)?
A7: We offer specialty-grade compounds that are engineered to resist H2S-induced embrittlement, making them safe for sour well environments.

Q8: What is the typical lead time for a custom OEM order?
A8: Standard sizes are often in stock. Custom OEM orders with laser marking typically ship within 2 to 3 weeks depending on the volume.
