9 Inch OD Flat Pipe Wiper with Customizable ID and Oil-Resistant Elastomer for Drill Pipe Cleaning

Product Overview

Product Parameters and Specifications

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

1. Pipe-Surface Review: Identify joints, scale, burrs and maximum passing diameter. Inspect the wiping edge for cuts and tearing during service.

2. Wear Monitoring: Check edge condition, permanent distortion and wiping effectiveness; service life depends on movement, fluid, solids and installation.

3. Fluid Compatibility: Provide mud, oil, cleaning-agent and additive details for compound review; no universal solvent compatibility is implied.

4. Fit Selection: Review opening size, hardness, thickness, retention and pipe speed together to balance wiping contact and friction.

FAQ

Q1: What information is needed for a custom opening?
A: Send ID, OD, thickness, dimensional tolerances and mounting details with a drawing revision or removed sample. Include tubular and joint dimensions, fluid, temperature and movement for quotation and fit review.

Q2: Can you manufacture wipers with non-circular or unique shapes?
A: Other profiles can be reviewed from CAD drawings and mounting information. Confirm geometry, tooling and sample acceptance separately from this flat circular wiper.

Q3: Is there a minimum order quantity (MOQ) for non-standard sizes?
A: Confirm the current minimum quantity for the selected dimensions, compound and tooling in the quotation. Include trial and production quantities in the enquiry.

Q4: How do you ensure the ID will fit my pipe correctly?
A: Opening selection depends on pipe and joint dimensions, material hardness, thickness, mounting and movement. Agree the required fit and verify the sample against the equipment; no universal undersize allowance is specified.

Q5: What is the lead time for a completely custom-sized wiper?
A: Confirm timing after drawing, compound, tooling and quantity review. Agree sample acceptance and production delivery in the quotation rather than relying on a fixed sample schedule.
