Heavy Duty 9" Chemical Resistant NBR Washer Pipe Wiper for Downhole Tool Protection

These 9-inch NBR rubber discs are surface pipe wipers for removing adhering drilling mud and residue from the outside of tubulars during tripping operations. Review the center opening, pipe-body diameter, tool-joint passage and support arrangement for the installed equipment. Mud recovery depends on the complete collection system and operating conditions. The wiper is not a downhole MWD/LWD protective component or a well-pressure barrier.

• Premium NBR Construction: NBR compound selection depends on the actual petroleum-based fluid, drilling additives, temperature and exposure duration.

• Surface Pipe Wiping: Removes adhering residue from the external pipe surface; review solids loading and tool-joint passage with the installed wiping arrangement.

• Superior Mud Recovery: The nominal 9-inch disc works with a suitable opening profile and support arrangement; mud collection requires the rig recovery system.

• Reinforced Tear Resistance: Specify rubbing duty, solids exposure and inspection criteria. Confirm any reinforcement in the selected drawing.

9-Inch NBR Pipe Wiper Specifications:

As a leading sealing manufacturer, we provide not just products, but complete technical solutions. We empower global distributors with extensive OEM capabilities:

• Full Size Range: Send required outside dimensions and casing or tubing reference for manufacturing review.

• Material Variety: Review NBR, HNBR or alternative compounds for the actual service. Sour-fluid and high-temperature use require specific qualification.

• Bespoke Packaging: Individual plastic bags or sturdy branded boxes to suit your retail or field needs.

• Laser Marking: Confirm the marking method for your company logo, part numbers and batch identification.

• Inventory Coding: Specify barcode or QR labels and their location on the part or packaging.

Shanghai Qinuo Industry — Your trusted partner in energy.

In the demanding world of oil and gas, where extreme pressures and harsh environments are the norm, reliable sealing technology is the absolute heartbeat of safety and efficiency. Welcome to Shanghai Qinuo Industry. Backed by our state-of-the-art, ISO 9001:2015 certified manufacturing base—Jiangsu Ruowei Energy Technology—we stand at the forefront of delivering high-performance rubber solutions.

Our commitment to excellence begins on the factory floor with advanced manufacturing processes. For our critical rubber rings, we utilize precision preforming technology prior to final molding. Confirm molding-process controls and required compound tests with the order; preforming alone does not establish strength or pressure capability.

Quality is our absolute cornerstone. We enforce a rigorous, full-process inspection system. Our dedicated team strictly monitors every phase—from pre-production material analysis, through in-production process control, to comprehensive post-production final testing—ensuring the ultimate delivery of fully qualified products. Furthermore, we implement a unified coding system across our production line. This guarantees complete end-to-end traceability for every single component we manufacture.

We specialize in premium rubber seals and comprehensive repair kits for downhole tools and manifold equipment. Our extensive portfolio includes Rubber O-Rings, Gaskets, Hammer Union Seals, Swivel Joint and Plug Valve seal kits, alongside Rubber Swab Cups, Oil Packer Elements, and Wireline Oil Saver Rubbers. Beyond our standard range, we excel in custom-engineered parts, precisely tailored to your unique requirements.

Driven by a team of seasoned professionals, we are unwavering in our mission: to deliver exceptional, reliable products on time, and at highly competitive prices.

For replacement selection, provide the mud base fluid, additives, cleaning chemicals and exposure temperature. Include the removed wiper condition, such as swelling, surface cracking or torn opening edges, with photographs. Review compound compatibility separately from the opening and support-frame fit.

Q1: Why choose NBR material for these 9" pipe wipers?
A1: NBR is commonly considered for oil-exposed rubber parts. Review the specific compound against the actual mud, additives and operating temperature.

Q2: Can these rubber discs protect my downhole MWD tools?
A2: This surface pipe wiper removes residue from external tubular surfaces. It does not establish protection of downhole MWD tools.

Q3: Is custom laser marking available for our company brand?
A3: Send the logo, part number and required identification method. Confirm marking suitability for the selected rubber and service.

Q4: Do you offer custom inner diameters for non-standard pipes?
A4: Send pipe-body OD, largest tool-joint OD, required opening and a sample or drawing. Pipe weight alone is insufficient to specify the wiping opening.

Q5: What is the maximum temperature these NBR wipers can handle?
A5: Confirm the selected NBR compound limits against fluid temperature, duration and movement. The listing does not establish one temperature rating for every compound.

Q6: Can you provide different colors for size classification?
A6: Yes, we can produce wipers in various colors or add colored stripes to help rig crews quickly identify the correct part on-site.

Q7: How do you ensure the wipers don't swell in drilling fluids?
A7: Specify the actual mud formulation, immersion temperature, exposure period and acceptable volume or hardness change. Request the relevant compound test results.

Q8: What is your typical lead time for a custom OEM order?
A8: Confirm quantity, drawing, marking and packing requirements for a current delivery quotation.
