Our industrial-grade 9-inch flat pipe wipers are essential for maintaining clean drill strings and a safe rig floor. While the outer diameter (OD) is a standardized 9 inches, the core value of our service is Precise Inner Diameter (ID) Customization. We engineer the internal opening to provide the exact amount of interference fit required for your specific drill pipe size, ensuring optimal wiping tension and fluid containment without premature wear or tearing.

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
Q: What is the benefit of a custom ID over a standard one?
A: A custom ID ensures the wiper has the perfect amount of contact pressure. Too loose, and mud remains on the pipe; too tight, and the wiper will tear. We tailor the ID to your exact pipe OD.
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: Simply provide the OD of your drill pipe, and our engineering team will calculate and produce the correct wiper ID for an optimal fit.
Q: Is your material resistant to oil-based drilling fluids?
A: Yes, our NBR and HNBR compounds are specifically formulated for constant exposure to petroleum-based fluids and common drilling chemicals.
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.
