Often the failure of subsea bolts has been a major cause of gas or oil leakage in offshore installations, so along with the access difficulties for maintenance teams, preventing the premature failure of these components is certainly desirable wherever possible. 

A comprehensive range of corrosion tests have been carried out on our newly developed Everlube 1174® Coating, in combination with a variety of pre-treatments.

The results show that Everlube 1174® will provide 1500hrs of salt spray protection when applied over a phosphate pre-treatment, 2500hrs over Zinc plating and 5000hrs over a Cermet basecoat.  We tested two bolts and after 1500hrs in the salt spray cabinet as per ASTM B117, the bolts showed near zero corrosion and easy removal of the nut.

Everlube 1174® coated bolts after 1500hrs salt spray testing showing near zero corrosion and easy removal of the nut.

Everlube 1174® is a low VOC, low friction, load bearing, thin film, resin-bonded, corrosion resistant, thermoset PTFE coating.

Everlube 1174® also acts as an excellent insulating shield between dissimilar metals due to its high dielectric strength.  This helps to alleviate the problem of galvanic corrosion.

In addition, subsea bolting systems can come into contact with a wide variety of chemicals, from those present in sea water to those used in various oil extraction equipment.  Hydraulic fluids for example, are extremely aggressive and can readily breakdown low grade coating systems.  Everlube 1174® has been formulated to resist all current hydraulic fluids used in the oil and gas industry.

Typical applications include wellheads, Xmas tress flanges, structural connections and flanges.

Neodymium Iron Boron rare earth magnets are utilised in power generation turbines. A multitude of these magnets are bonded together to increase the overall level of magnetism. This process leads to two potential issues: Firstly, any adhesive or coating between the magnets acts as an air gap and thus reduces the level of magnetism and secondly NdFeB magnets corrode extremely aggressively. This corrosion issue is exacerbated by the environmental conditions that the wind turbines face.

The corrosion mechanism for NdFeB magnets is detailed in Figure 1. This shows that when exposed to water or humid conditions, the Neodymium rich layers at the grain boundaries react to form Neodymium Hydroxide. The effect of this conversion from Nd to Nd(OH)3, is a large volume increase along the grain boundaries, leading to cracking and degradation of magnet properties.

Curtiss Wright Surface Technologies (CWST) has been working on a solution to these issues. This involved developing a high grade anti-corrosion coating with minimal coat thickness (effective air gap). The current market leader for corrosion protection is CWST’s own Everlube 6155 providing 500hours protection in the ASTM B117 salt spray test.

After extensive studies and trials, CWST is pleased to announce they have successfully developed a coating system which will provide 1000hours salt spray resistance for NdFeB magnets at a coating thickness of just 25um. This NEW coating system – Everlube 1155 is environmentally friendly, easy to apply and a cost effective solution to this critical problem.

Curtiss-Wright Corporation who first began trading on the New York Stock Exchange (NYSE) on 22nd August 1929, commemorated their 85^th anniversary of being listed by ringing The Closing Bell® on Friday, August 22 2014.

E/M Coating Services continues to be at the forefront of coating development and have now developed coatings specifically to reduce friction in powder processing plants.

The challenges of efficient powder processing are felt within a wide range of industries and one company that is familiar with these challenges is Freeman Technology.  They have spent the last 14 years researching powder flow with their FT4 Powder Rheometer® which enables precise and highly reproductible dynamic shear and bulk property testing.

In order to devise a viable solution E/M Coating Services and Freeman Technology teamed up to compile a unique research paper on how dry film lubricant coatings can reduce wall friction properties in powder handling equipment, see attached PDF for full details.

Contact us for more information on dry film lubricants or to discuss your coating requirements in more detail.

We are delighted to announce the launch of the new Everlube Products website.  Everlube are pioneers in the design, formulation and manufacture of solid film lubricant technology.  Our engineered coatings meet a wide variety of industry and military specifications and can improve performance and provide protection against corrosion, wear, galling and seizing, why not visit our website today to find out more.

Bloodhound SSC is a high technology project aimed at breaking the Land Speed Record!  The project has two main aims: the first is to build a supersonic car capable of reaching speeds in excess of 1000 mph and the second is to encourage a new generation of engineers by bringing science, technology, engineering and maths to life in the most exciting way possible.

EM Coating Services are excited to be involved with such an innovative project and recently completed work on 30 different structural parts which will form part of the bronded framework of the car.

Being part of the Curtiss-Wright family this sponsorship continues the long tradition of involvement with such projects as our founders Glenn Curtiss and the Wright Brothers undertook the first recognised flight in 1903, closely followed in 1907 when Glenn Curtiss became know as the “fastest man in the World” when he rode his V-8 motorcyle at a speed of 136.4 mph.

Contact us for more information about our coating services and products or alternatively visit the Bloodhound Project website.

We are proud to unveil the new EM Coatings website that has been designed to highlight the variety of coating services, applications and products that we offer.  Our company operates to the highest quality standards and is continually looking for ways to improve our customer service and keep our customers informed about our new innovative coating products and services, contact us to find out more.
