• Not all rubber is created equal. For industrial drilling, Nitrile (NBR) is the gold standard due to its specific chemical properties:
• Superior Oil Resistance: NBR is highly resistant to hydrocarbons, making it ideal for use with Oil-Based Muds (OBM) and synthetic drilling fluids. It will not swell or degrade like natural rubber or EPDM when exposed to oil.
• High Abrasion Resistance:Our NBR formulation is built to withstand the constant friction of the drill pipe, extending the service life of the wiper even during deep-hole tripping.
• Excellent Tensile Strength: Provides the "snap-back" elasticity required to maintain a tight seal around the pipe joints and protectors.

1. Exceptional Tear Resistance: The high tensile properties prevent the wiper from "chunking" or tearing when encountering rough pipe joints or external scale.
2. Optimal Compression Set: Maintains its original shape and wiping edge longer than standard elastomers, ensuring a consistent seal over thousands of cycles.
3. Industrial Chemical Shield: Formulated to withstand constant exposure to cleaning solvents, hydrocarbons, and aggressive industrial fluids.
4. Constant Stripping Pressure: The elasticity is calibrated to provide maximum wiping force without causing excessive friction-induced heat.

Q1: Why should I choose NBR over Natural Rubber for my pipe wipers?
A: While Natural Rubber is excellent for water-based fluids, it fails quickly when in contact with oil. NBR (Nitrile) is essential if you are using oil-based muds (OBM) or if the well contains hydrocarbons, as it prevents the wiper from swelling and losing its sealing shape.

Q2: Can these NBR wipers withstand high-temperature drilling?
A: Our standard NBR wipers are rated up to 120°C (248°F). For HPHT (High Pressure High Temperature) wells, please contact us for our HNBR (Hydrogenated Nitrile) options, which can handle even higher thermal loads and H2S exposure.
