Industrial Rubber Drill Pipe Wiper 9-Inch Flat NBR HNBR Stripper for 68mm ID Oil and Gas Tubing

9-Inch Flat Rubber Drill Pipe Wiper with Listed 68 mm Opening

This nominal 9-inch flat rubber pipe wiper removes adhering mud and residue from external tubular surfaces during retrieval. The listed 68 mm dimension describes the wiper opening, not tubing bore size. Review pipe-body OD, tool-joint OD and mounting support for the actual wiping operation.

Use the wiper with suitable support and mud collection. It is a surface wiping component, not a well-pressure containment seal.

Technical Specifications

Material Engineering (Optimized for Oilfield Chemistry)

Select the exact NBR or HNBR compound using the fluid formulation, additives, exposure temperature and mechanical duty:

1. Nitrile (NBR): Review compatibility with the actual OBM, fuel or cleaning formulation. Request relevant compound data and agree test conditions.
2. Hydrogenated Nitrile (HNBR): Review alternative compound requirements separately from the dimensional fit. High-temperature or H2S exposure requires specific qualification.

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.

FAQ

Q1: Can this 9-inch wiper be used with Oil-Based Muds (OBM)?
A: Provide the specific OBM formulation, additives and exposure temperature. Review compound immersion data and acceptable volume or hardness changes rather than assuming no swelling.

Q2: How do I ensure the 68mm ID is the correct size for my tubing?
A: Confirm the measured opening and tolerance, pipe-body OD and largest tool-joint OD against the drawing. Equal nominal opening and pipe diameters do not establish an interference fit or suitable wiping contact.

Q3: How does temperature affect the performance of the rubber?
A: Review actual fluid and ambient temperatures at the surface wiper, exposure duration and movement. Confirm limits for the selected compound; bottom-hole temperature alone does not specify the surface wiping duty.

NBR or HNBR Replacement with the Same Wiper Geometry

When reviewing an alternative compound for this flat disc, keep the dimensional drawing, opening tolerance, thickness and mounting interface with the order. Review hardness and wiping contact separately from chemical and temperature compatibility. Changing the material family does not automatically preserve fit or establish a pressure rating.

For repeat orders, provide the selected compound reference, drawing revision, fluid conditions and quantity. Include the installed support arrangement and removed-part photographs for replacement matching.
