9 Inch Drill Pipe Rubber Wiper for Oilfield Drilling Operations
Product Overview
Our Premium 9-inch NBR Rubber Wiper is engineered specifically for the demanding environments of casing and tubing operations. Manufactured from high-grade Nitrile Butadiene Rubber (NBR), this pipe wiper provides an exceptional seal to strip drilling mud, oil, and water-based fluids from the pipe exterior as it is pulled from the wellbore.
As a specialized oilfield seal manufacturer, we ensure that our wipers offer the perfect balance of flexibility and toughness, maintaining a clean rig floor and protecting your equipment from corrosive fluids.
Key feature and benefits
-
High-Grade NBR Compound: Superior resistance to petroleum-based oils, crude, and hydraulic fluids.
-
Precision Stripping Action: Designed to fit snugly around casing and tubing, ensuring zero fluid carry-over.
-
Reinforced Structural Integrity: Available with internal steel rings to prevent "dishing" or deformation under high-speed pulling.
-
Universal Compatibility: Our 9" (228.6mm) OD design fits standard wiper bowls and master bushings used in global drilling operations.
-
Eco-Friendly Operation: Minimizes fluid spills, assisting rigs in meeting environmental "zero discharge" requirements.

Appliactions
The 9" Rubber Pipe Wiper is widely used in both onshore and offshore drilling environments, including:
-
Drilling Rigs: Cleaning drill strings during tripping operations.
-
Workover Units: Managing fluids during well maintenance and completion.
-
Casing Operations: Wiping casing walls to prevent fluid migration.
-
Environmental Protection: Essential for "Zero Discharge" rig sites to keep drilling fluids within the well system.
Why choose our rubber wiper?
As a specialized sealing solution manufacturer, we understand the harsh conditions of the oil patch. Our products are:
-
Chemical Resistant: Built to handle water-based muds (WBM), oil-based muds (OBM), and acidic well conditions.
-
Customizable: We can adjust the rubber compounding (durometer and elasticity) to meet specific well depths and pressure requirements.
-
Quality Assured: Every 9 inch mud wiper undergoes rigorous tension and oil-immersion testing before shipment.
-
Manufacturer Direct: Buying directly from the factory ensures competitive pricing and shorter lead times for global oilfield service companies.
