🧿1. Repair Steps for Oil Pipe Leaks

Repairing oil pipe leaks requires a systematic approach to ensure safety and effectiveness.

1. Safety First, Shut Down and Depressurize:
Immediately stop the operation of related equipment (such as pumps and engines).
Isolate the upstream source of the oil system.
Slowly Release Pressure: Open the system pressure relief valve or use other safe means to completely release the oil pressure in the pipeline. This is the most critical step to prevent high-pressure oil from spraying out and causing danger or personal injury.
2. Locate and Clean:
Pinpoint the leak. Sometimes the leak may be very small, requiring careful wiping of the pipe surface before observation.
Thoroughly clean the area around the leak. Use a metal brush, sandpaper, or detergent to remove oil, rust, paint, and dust. Ensure the repair surface is clean, dry, and roughened to ensure adhesion of subsequent repair materials.
3. Select and Apply Repair Method:
Select the most appropriate repair method based on the leak, pipe material, pressure, and environment (see the "Leak Repair Clamp" section below for details). Strictly follow the instructions for the selected repair product (such as leak repair clips or patching compound).
4. Curing and Testing:
If using adhesives (such as sealants or epoxies), allow sufficient curing time.
After the repair is complete, perform a low-pressure test by slowly introducing the medium and observing for leaks.
Once there are no leaks, gradually restore the pressure to normal operating pressure and continue observing for a period of time.

🧿II. What types of pipes are generally oil-resistant?

The selection of oil-resistant pipes primarily depends on the inner lining or the main body material. The following are common oil-resistant pipe types:

1. Oil-Resistant Rubber Hose:
NBR (Nitrile-Butadiene Rubber) Hose: This is one of the most commonly used and economical oil-resistant hoses. It offers excellent resistance to petroleum-based hydraulic fluids, fuels, and lubricants. Oil resistance increases with increasing acrylonitrile content.
FKM (Fluorocarbon Rubber) Hose: It offers excellent oil and high-temperature resistance (up to 200°C or higher), and is resistant to a variety of harsh oils and chemicals, but is very expensive. Typically used in high-temperature and high-pressure environments.
PTFE (polytetrafluoroethylene, Teflon)-lined pipe: Features almost perfect chemical inertness, resisting all oils and solvents. Its interior is very smooth and has a low friction coefficient. It is often used in applications requiring high purity and corrosion resistance.
CR (chloroprene rubber) pipe: Offers excellent oil, weather, and aging resistance and is commonly used for fuel transportation and external hydraulic lines.
2. Metal Pipes:
Stainless steel pipe (such as 304 and 316L): Naturally resistant to most oils, it offers high strength, high temperature, and high-pressure resistance, making it the preferred choice for permanent piping systems.
Carbon steel pipe: Commonly used in large, fixed hydraulic systems, it typically requires internal galvanizing or other corrosion protection treatments to prevent rust. While inherently oil-resistant, it is susceptible to corrosion from moisture in the oil.
3. Oil-Resistant Plastic Pipes:
Nylon (PA) pipe: Lightweight, oil-resistant, and easy to bend and install, it is commonly used in pneumatic and low-pressure hydraulic systems. Polyurethane (PU) tubing: It offers excellent wear resistance and oil resistance and is often used in applications with frequent movement, such as the oil tubing in machine tool drag chains.

In summary: For general hydraulic and lubricating oils, NBR nitrile rubber tubing is the most common choice. For fuel or high-temperature environments, consider FKM fluororubber tubing or PTFE tubing. For stationary, high-pressure systems, stainless steel tubing is the most reliable choice.

🧿 III. Advantages of Using Oil-Resistant Leak Repair Clamps

Leak repair clamps (also known as patch sleeves or leak repair clamps) are designed specifically for quickly plugging leaks in pipelines. Using oil-resistant leak repair clamps offers the following significant advantages:

1. Fast and Efficient:
It eliminates the need for prolonged system downtime and complex welding, cutting, or tubing changes.
It can typically be installed in minutes to tens of minutes, significantly reducing downtime and production losses.
2. Safe and Reliable:
Using pressurized plugging technology, installation can be performed even when the system is partially depressurized (at low pressure) or when only a small leak is present, minimizing the environmental and safety risks associated with large oil leaks. Designed with a sealing ring and mechanical fastening structure, it can withstand high operating pressures and provide a durable and reliable seal.
3. Wide Application:
It is suitable for pipes of various materials, including steel pipes, cast iron pipes, PVC pipes, and hoses.
It can repair a variety of damage types, including cracks, holes, pinholes, and corrosion leaks.
4. Cost-Effective:
It eliminates the material and labor costs of replacing an entire section of pipe.
It avoids the significant economic losses caused by prolonged downtime.
5. Easy Operation:
Installation typically requires only a wrench, requiring minimal operator skill. Ordinary workers can operate it with simple instruction.

Final Recommendation:

For temporary emergency/quick repairs: Oil-resistant leak repair clamps are the fastest, safest, and least labor-intensive method.
Small pinholes or cracks: Metal plugging rods or epoxy-based sealants may also be considered (the surface must be thoroughly cleaned and pressure relieved).
Permanent repair: For critical pipelines, leak repair clamps can be used as a temporary or semi-permanent solution. During planned outages, it is recommended to replace the entire section of oil-resistant piping (such as stainless steel or a certified oil-resistant hose) to maximize service life and reliability.
