Product Overview

Product Parameters and Specifications

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

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.

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.
