9-Inch Flat Rubber Drill Pipe Wiper with Listed 68 mm Center Opening
This nominal 9-inch flat rubber drill pipe wiper removes adhering mud and residue from external pipe surfaces during retrieval. The listed 68 mm dimension refers to the wiper center opening. Confirm pipe-body OD, largest tool-joint OD and support fit; tubing bore diameter alone does not establish wiping fit.
Use the wiper with suitable support and mud collection. Review actual fluid exposure and rubbing duty; this surface wiping component does not contain well pressure.
Key Features and Benefits
- NBR Compound Review: Specify mud formulation, cleaning chemicals, temperature and wear requirements for compound selection.
- Opening Fit: Confirm the listed 68 mm opening and tolerance against pipe-body and tool-joint dimensions, including any coating.
- Flat Disc Support: Match outside dimensions, thickness and retaining surfaces to the installed support arrangement.
- Mud Handling: Use external wiping with collection, housekeeping and operating procedures. No accident-prevention guarantee is established by the wiper alone.

Why Choose Our Drill Pipe Wipers?
Confirm any internal reinforcement against the selected drawing. An external support frame is a separate equipment interface. Specify mud solids, pipe speed and tool-joint passage to review the wiping profile and inspection requirements.
Our Company
Shanghai Qinuo Industry is where high-pressure engineering meets reliable manufacturing. Supported by our ISO 9001:2015 factory, Jiangsu Ruowei Energy Technology, we are experts in high-performance rubber sealing for the oil and gas sector.
Our Secret to Strength:
Confirm molding-process controls and required compound tests with the order. Preforming alone does not establish tensile strength, tear resistance or pressure capability.
Full Traceability and Quality:
Quality is our cornerstone. Our team monitors everything from raw material to final testing. Specify batch identification, marking location and inspection documents required for your records.
What We Offer:
1. Sealing Essentials: O-Rings, Gaskets, and Hammer Union Seals.
2. Repair Kits: Comprehensive kits for Plug Valves and Swivel Joints.
3. Specialized Rubber: Packer Elements, Swab Cups, and Oil Saver Rubbers.
4. Custom Engineering: Tailored parts built to your exact specifications.
Get the reliability you need at a price that makes sense. Shanghai Qinuo Industry delivers professional service and on-time shipments for energy partners worldwide.
Pipe Coating and Tool-Joint Clearance Review
For the listed 68 mm center opening, provide measured pipe outside dimensions including coatings or protectors, together with the largest tool-joint diameter. Include the opening tolerance, disc thickness and support interface from the drawing or sample. Review wiping contact and passage through the installed arrangement together.
Specify pipe travel speed, solids and fluid exposure when requesting a replacement. A matching nominal opening alone does not guarantee coating protection, wiping performance or service life.
