Specialised Coating
Specialty Coatings including Xylan and Everslick
Both Xylan and Everslik are commonly used because of their combination of Corrosion Resistance and Chemical Resistance. Both Are popular in the Oil and Gas sector, but have different applications.
Xylan is a brand name of a range of coatings, each of which can be used for different applications but typically they contain PTFE and offer improved Wear Resistance, Reduced Friction and Heat Resistance. They are most popular as a coating for components that will be used in subsea environments.
Everslik is a dry lubricant coating that is often combined with different materials depending on the application. It’s one of a number of Molybdenum Disulphide based coatings that are supplied under various trade names. Everslik will give your components added protection against corrosion, is low friction, and can operate at a wide range of temperatures.
STSI Facility is at your service to provide you with the most technically advanced forms of industrial coatings.
WE OFFER THE FOLLOWING SPECIALTY COATINGS
- Zinc Phosphate Coating: (for equipment that may be exposed to severe environments)
- Xylan Coating: (generally used to reduce friction and for protection in corrosive environments)
- Everslick Coating: (used for its lubricity and corrosion resistance)
Sand Blasting and Painting
“Sandblasting”, abrasive blasting is the use of abrasive “Media” under high pressure air to erode the surface of an object down to its parent material. Over time, metals by nature oxidize (e.g.. rust) and lose their luster and shine. Depending on the media used, dull metals can be made to look new again. Painted surfaces can be quickly cleaned away saving time and effort. Abrasive blasting is not limited in its use and has many applications to which it can be used with great effect. Grit blasting is ideal for aggressive cleaning applications.
Paint is the most commonly used material to protect steel. The protective paint systems usually consist of primer, undercoat(s) and finish coats. Each coating ‘layer’ in any protective system has a specific function, and the different types are applied in a particular sequence of primer followed by intermediate / build coats in the shop, and finally the finish or topcoat. We verify the paint materials are in compliance with the specification and this includes checking packaging and labelling; verifying the condition of paint in the container; and taking samples for testing. One of the most important inspection tasks we perform during a painting project is measuring the thickness of the paint coat to always make sure it’s the right thickness.
Drops:
STSI has extensive experience with this type of inspection, we have been using DROPS Awareness and Prevention Format and the DROPS Inspection Guide, for several years within the oil and gas industry, aiming at avoiding potential accidents. We are qualified to conduct dropped object surveys for all types of
structures and areas, and the report will consist in an inventory of equipment within the structure, an assessment of its integrity and the recommended secondary retention method, including the inspection frequency for each item.
The surveys consider all items and attachments to the structure with regard to primary and secondary retention devices, to ensure they are secured or and fit for purpose condition. The report will also assess any corrosion to the structure, fixtures and equipment. Report on severity, location, and all areas of concern, will be identified and detailed on the inspection report with individual photos and recommendations.
