Seals for Industry
RRT and partners is a supplier of top quality, highly reliable products to the Oil & Gas, Mining, Steel Manufacturing, Press Forming, Beverage and Machine Tool industry. In these most challenging industry’s our customers benefit from our comprehensive field experience and extensive knowledge in the sealing technology.
Whereas some sealing material is a non stock item and waiting times may be 8 to 10 weeks we machine Seals and “O” Rings on the spot and our turnaround time is 3 to 4 days, with our experience and if perhaps you are having trouble with reduced seal life or containment we can suggest other profiles and manufacture the seal very quickly.
For polymeric seals the Oil & Gas industry provides the most hostile environment (mechanically and chemically). It is essential to fulfill the steadily increasing demands in safety, reliability and cost efficiency for all Oil & Gas applications.
RRT is equipped with state-of the-art R&D resources including computer aided engineering (CAE) tools, advanced seal test rigs and highly qualified polymer-scientists operating a materials characterization centre. This technological expertise results in the innovative development of materials that set new performance standards for the Oil & Gas industry. A variety of polymers can be used as sealing materials in the Oil & Gas industry. Basically they can be separated into five groups:
- Elastomers
- Thermoplastic Elastomers
- Flouro-elastomers and its compounds
- Thermoplastics
- Thermosets
Today, Elastomers are the most frequently used materials for oilfield applications. For some applications NBR (nitrile rubber) or HNBR (hydrogenated nitrile rubber) is the material of first choice, because of their chemical resistance. In case of higher requirements concerning chemical and temperature resistance fluorinated elastomers (FKM/FPM, TFE/P, FFKM) come into consideration.
In some applications elastomers alone do not provide sufficient sealing capabilities. In these cases other high quality materials such as PTFE or PEEK need to be selected either in combination with elastomers for anti extrusion purposes, or even as a sealing material itself.
However, RRT and Partners has developed a wide range of thermoplastic elastomers and provides oilfield compatible Polyurethanes, which offer superior abrasion and extrusion resistance compatible with oilfield fluids, including sour gas according to NORSOK. When elastomers are exposed to high gas pressures for a certain period of time and this pressure is released quickly, material deterioration may occur. The effects of explosive decompression (ED) can be influenced by specific additives, which alter the
Permeability of the material. RRT and Partners has a wide range of ED resistant materials in accordance with the international NACE resp. NORSOK test standards available.
