Our 9" OD Flat Pipe Wiper is an essential tool for maintaining a clean and safe rig floor during tripping operations. Engineered to wipe drilling fluids (mud) from the drill string as it is pulled from the borehole, this wiper significantly reduces fluid loss and environmental impact.
Manufactured from high-tenacity, oil-resistant elastomers, our wipers are designed to withstand the abrasive nature of drill pipes and the aggressive chemical composition of modern drilling muds. With a fully customizable Inner Diameter (ID), we provide a perfect fit for any drill pipe size, ensuring maximum wiping efficiency.

Material Selection
1. NBR (Nitrile Butadiene Rubber) - Standard Grade
Features: Excellent resistance to petroleum-based oils, water, and drilling muds. High abrasion resistance.
Temperature Range:** -40°C to +120°C (-40°F to +248°F).
Best For:** General drilling operations and standard mud systems.
2. HNBR (Hydrogenated Nitrile) - Premium Grade
Features: Enhanced thermal stability and superior mechanical strength. Resistant to sour gas (H2S) and high-pressure environments.
Temperature Range: -40°C to +160°C (-40°F to +320°F).
Best For:** High-temperature, high-pressure (HTHP) wells and aggressive chemical environments.
Key Benefits
Exceptional Tear Resistance: The high tensile properties prevent the wiper from "chunking" or tearing when encountering rough pipe joints or external scale.
Optimal Compression Set: Maintains its original shape and wiping edge longer than standard elastomers, ensuring a consistent seal over thousands of cycles.
Industrial Chemical Shield: Formulated to withstand constant exposure to cleaning solvents, hydrocarbons, and aggressive industrial fluids.
Constant Stripping Pressure: The elasticity is calibrated to provide maximum wiping force without causing excessive friction-induced heat.
FAQ
Q1: Since there are no standard specifications, how do I place an order?
A: Simply provide us with your required Inner Diameter (ID), Outer Diameter (OD), and Thickness, along with the operating environment (temperature and type of fluid). We will provide a technical quote based on your specific needs.
Q2: Can you manufacture wipers with non-circular or unique shapes?
A: Yes. In addition to standard flat circular wipers, our ODM service can create rectangular, oval, or complex geometric seals based on your CAD drawings.
Q3: Is there a minimum order quantity (MOQ) for non-standard sizes?
A: We support both small-batch specialized orders and high-volume mass production. Contact us to discuss the most cost-effective solution for your volume.
Q4: How do you ensure the ID will fit my pipe correctly?
A: We typically recommend an ID slightly smaller than your pipe OD to ensure a proper "wipe." We can customize this tolerance based on your specific application (e.g., drill pipe, casing, or industrial tubing).
Q5: What is the lead time for a completely custom-sized wiper?
A: Depending on the complexity and tooling requirements, custom samples are usually ready within 15-25 days, with mass production following shortly after approval.
