NBR Industrial Rubber Pipe Wiper for Enhanced Drilling Performance and Safety
9-Inch NBR Flat Pipe Wiper | External Drill String Wiping
This NBR industrial rubber pipe wiper removes adhering mud from external drill string surfaces during retrieval. Match the flat disc and opening to the pipe and installed support arrangement.
We provide custom ID, OD and thickness to meet your specific pipeline requirements.
The NBR wiping element works with the site mud collection system. It does not retain well pressure or guarantee a dry rig floor.

Why NBR? The Material of Choice for Oilfield Performance
- Nitrile (NBR) compound selection for drilling service depends on fluid exposure and mechanical duty:
- Oil Compatibility: Review the selected NBR compound against the exact oil, mud additives and cleaning chemicals. Do not assume all OBM or synthetic fluids have the same compatibility.
- Abrasion Duty: Specify pipe speed, solids exposure and surface condition. Review wear and replacement criteria for the installed wiper.
- Elastic Response: Confirm compound hardness and opening geometry for pipe-body contact and tool-joint passage.

Key Benefits for Drilling Operations |
||
|
Enhanced Drilling Performance External wiping can assist removal of adhering mud before pipe inspection or storage. Review mud condition, opening fit and handling sequence for the actual operation. |
Rig Floor Mud Handling Use the wiper with suitable mud collection, housekeeping and operating procedures. Wiping alone does not establish slip prevention or environmental compliance. |
Equipment Longevity Review solids loading, chemical exposure and condition of the removed wiper. Inspect the wiping edge and support interface according to the equipment maintenance procedure. |
FAQ
Q1: Why should I choose NBR over Natural Rubber for my pipe wipers?
A: NBR is commonly considered for oil-exposed rubber components. Select the exact compound using the actual fluid formulation, additives and temperature, and review relevant immersion data.
Q2: Can these NBR wipers withstand high-temperature drilling?
A: Confirm the selected compound against actual fluid and ambient temperatures, duration and rubbing duty. HNBR alternatives require specific review; the material name alone does not establish high-temperature or H2S suitability.

Inspection and Reorder Information for a 68 mm Opening Wiper
For this listed configuration, verify the 68 mm center opening against the removed sample or drawing. Check outside diameter, thickness and retaining surfaces separately from pipe-body and largest tool-joint dimensions. Record the drawing revision and selected NBR compound for repeat orders.
Send close views of opening-edge wear, cracking or swelling with the mud formulation and cleaning exposure. These details help review the replacement specification; they do not establish a fixed service life or diagnose every cause of damage.
