Slip Rings for the Oil & Gas Industry

The swelling demand for hydrocarbons is continuously compelling oil and gas companies to discover and exploit fresh downhole reserves, which usually entails withstanding harsh downhole conditions. Some of these conditions include high pressure and high temperatures (HPHT) that condense the technologies and devices used to mine these reservoirs.

HPHT activities have been classified into three classes. Class 2 comprises wells containing the pressure of 20,000 psi and temperatures of almost 400 0F as illustrated in the diagram below, and a significant percentage of them either are currently available or are future undertakings in North Sea, Africa, parts of Asia, and China.

The modern oil and gas firms are focussed in solving major issues encountered during the creation and exploitation of such reserves, and leading machine producers and service firms are betting on planned inventions to solve such problems.

 

a)Manufacturing Reliable Slip Rings for HPHT Uses

To certify that downhole reserves are secure and durable, research and development of innovative plastic substances- which can bear up with challenging conditions- has been given priority. Nevertheless, the task of testing HPHT equipment is quite complicated and time-consuming; it can run for several months to years.

Oil & Gas sealing solutions have been labelled as a big concern regarding the reliability of safe slip rings and valves in HPHT settings. A study carried out by Oil, and Gas iQ found out that 57,000 industry participants strongly feel that sealing products are the dominant technology gap trailed by testing and safety concerns.

From the above diagram, elastomeric materials hit their confines and can cause explosions if not controlled in time. The best alternative to elastomer slip rings is thermoplastic slip rings because they contain better chemical and heat resistance, and lack quick gas decompression performances.

To solve these current industry problems and better serve our clients, MOFLON Technologies has produced and tested unique thermoplastic slip rings to be used in engineering processes on spring-energized processes.

Several designs for thermoplastic materials, primarily PTFE materials (A-H as illustrated below) projected as seal covers, have tested with isostatic pressures of 30,000 psi at temperatures of 482 0F. The major pressure-resistant sealing part of a slip ring is the seal jacket, which comprises of a non-corrosive metal coil.

Additionally, the test pressure for the majority of our onshore slip rings often apply safety elements of 1.5. Our test results failed to show any significant alterations on the material tensile strength, implying that the development of mechanical aspects cannot be projected on such grades throughout the slip ring's lifespan.

Because back up seals often inhibit extrusion from the seal cover content at HPHT, MOFLON employs a new testing process to establish the performance of 16 different ratings of back-up slip ring materials. These seals comprise of various compositions or similar compositions like that of the covers since their primary role is to prevent the movement of content via the extrusion gap.

Chapter 2

Large Hose Reels

MOFLON manufactures fluid sealing products for large hose reel uses designed to offer functional elasticity for both offshore and onshore uses. Our unique rotary unions match well with large hose reels enabling consistent winding of hose and apparatus.

Recommended for pressures of more than 20,000 psi, MOFLON's rotary unions offer hydraulic, pneumatic, and chemical support to large hose reels. We manufacture standard and customized slip rings and rotary unions with a diversity of options for both single and compound flow channels, pressures, and fluid and electrical incorporation.

 

a)Merging Roles Saves time, Expenses, and Improves Quality

Nearly all heavy machinery in construction, Oil & Gas, and agriculture depend heavily on hydraulics. It is also good to note that many of these equipment employ moving systems, which demand the transfer of hydraulic fluids from stationary to moving parts.

MOFLON rotary joints serve this role well by acting as slip rings for hydraulics. However, rotary joints do not transfer electrical power or signals; hence, manufacturers produce separate hydraulic rotary joints and electric slip rings.

When slip rings and rotary joints are itemized separately, devices are more likely to fail and need additional assembly and maintenance. The use of a combined assembly- a slip ring and rotary union cohesively framed as a single unit- enhances economies of scale and minimizes the number of devices, distributors, and the probability of machine failure.

Research has shown that when slip rings and rotary unions are sourced from the same company, the user's design is cleaner, and the components are more resilient to environmental conditions, such as salt spray and extreme weather. With over 30 years' experience dealing with sealing solutions, MOFLON acknowledges the first-hand advantages of a combination system.

Buying slip rings and rotary joints separately have their disadvantages. First, the likelihood of human error surges from sourcing from two manufacturers. Second, the components are distributed independently instead of being packaged as one component, resulting in further logistical harmonization and scheduling. Lastly, users have to align and bolt the two devices together.

Equally, noticeable benefits are evident for having the rotary union and slip ring designed and assembled as a single combination component. First, the unit is easy to install on the equipment, with little assembly needed to put up the two sealing solutions. Second, the two devices are definite to be compatible since they were sourced from one company.

Thirdly, a combination unit decreases the overall expenditure. Lastly, buying and follow-up activities are done to a single firm instead of two- with one distributer, and the device expertise is comprehensive.

Chapter 5

Onshore & Offshore Applications

Offshore oil and gas equipment are acknowledged for their harsh conditions that often require high-performance sealing solutions. Integrating the right seal can prolong seal lifespan and minimize maintenance costs- both scheduled and unscheduled. This eventually maximizes production costs.

In the oil and gas sector, it is vital to strictly adhere to the market standards and the unique sealing contents as they emerge. By partnering with a manufacturer that has a comprehensive provision of compliant seals like MOFLON, oil and gas companies obtain higher processing performance while decreasing the number of intermediaries required to attain a new supply.

 

a)Rigorous Oil Reservoir Conditions Demand a Comprehensive Slip Ring Variety

There exist various factors triggering the need for a proliferation of slip rings in offshore uses. A single design can't cope with all the demanding and challenging sealing conditions of the oil and gas sector; where pressures are exceedingly high, odd temperatures and in specific, the integration of slip rings and bearings can be critical.

Fluids encountered include hydrochloric and formic acids, which are useful in acidizing and fracturing processes. Besides, aromatic hydrocarbons like benzene and toluene, carbon dioxide and oxidization inhibitors- applied to prevent corrosion of tubes and casings- are also used.

These fluids can make seals expand, lose essential sealing aspects, or even destroy them.

Apart from dealing with damaging chemicals, slip ring designing must also consider the effect of drilling mud, which is known to be abrasive. Many varieties are available based on diesel and mineral oils. It is evident that a single slip ring material will not serve all roles, hence a wide range is needed to ensure that various offshore oil & gas working conditions are attained through fluid resistance, durability, and friction resistance.
