Product Description
Product Overview
This 9-inch OD flat pipe wiper is used to remove carried fluid and debris from a moving tubular at the matched wiping interface. The existing specification lists a 68 mm opening; confirm the required ID and tolerance; custom-ID enquiries require the actual pipe OD, tool-joint envelope, mounting arrangement and drawing or sample. Confirm fit through the equipment requirements and sample review. The wiper is not a pressure-containment seal.

Material Selection
1. NBR (Nitrile Butadiene Rubber) - Standard Grade
Features: Candidate for selected oil and drilling-fluid wiping applications; confirm the exact fluid, additives and compound.
Temperature Range: Confirm limits for the selected NBR compound, medium and exposure duration.
Selection: Specify pipe movement, solids, mounting and wiping requirements.
2. HNBR (Hydrogenated Nitrile) - Premium Grade
Features: HNBR compound selection requires review of actual fluid and operating conditions; the material name does not establish H2S suitability or a pressure rating.
Temperature Range: Confirm limits for the specified HNBR compound and service medium.
Selection: State temperature, chemical identity and any gas exposure; qualify the exact compound where required.
Key Benefits
Pipe-Surface Review: Identify joints, scale, burrs and maximum passing diameter. Inspect the wiping edge for cuts and tearing during service.
Wear Monitoring: Check edge condition, permanent distortion and wiping effectiveness; service life depends on movement, fluid, solids and installation.
Fluid Compatibility: Provide mud, oil, cleaning-agent and additive details for compound review; no universal solvent compatibility is implied.
Fit Selection: Review opening size, hardness, thickness, retention and pipe speed together to balance wiping contact and friction.

FAQ
Q: What is the benefit of a custom ID over a standard one?
A: A custom opening allows the fit to be reviewed for the actual tubular and mounting. Confirm contact and joint passage with the required profile and sample; pipe OD alone does not establish the correct interference.
Q: Can you provide different colors for different ID sizes?
A: Yes. Many clients use custom colors to help rig crews quickly identify the correct wiper for the drill string.
Q: How do I specify the ID I need?
A: Provide pipe OD, maximum tool-joint or coupling diameter, mounting dimensions, wiper thickness, fluid, operating temperature and movement information. Include a drawing revision or removed sample to confirm the opening and tolerances.
Q: Is your material resistant to oil-based drilling fluids?
A: Confirm the exact oil-based fluid and additives, temperature and exposure duration against the selected compound. NBR and HNBR should not be treated as interchangeable for every drilling-fluid formulation.
Q: Do you offer custom branding for industrial distributors?
A: Absolutely. We can mold your logo into the wiper and provide private-label packaging with your barcodes and part numbers.
