Shotblasting – The Abrasive Protection

shot-blasting-nitec-ukShotblasting is a technological process which enables impurities of metal parts to be removed from a wide variety of surfaces, through the medium of abrasionShotblasting can be used as a preparation method performed before other processes, such as welding, colouring, painting, where imperfections must be eradicated to gain a perfect finish, join or seal.  It can also be used as a method of surface protection.  The end result of a cleaned metal surface depends on multiple characteristics.  These can be examples, such as the mass size of the abrasive particle, its shape, density, coverage of strokes (kg/m²), the particle impactor angle and the particle velocity.

The shotblasting process can be undertaken for multiple reasons – the cleaning, strengthening or polishing of metal.  These processes are used in almost every single industry which uses metal, including that of the aerospace, automotive, construction and transportation.  In order for shotblasting to take place, two technological processes can be undertaken – wheelblasting or airblasting.

Wheelblasting for the Shotblasting Process

Wheelblasting is the direct conversion of electric motor energy into kinetic abrasive energy through the use of a rotating turbine wheel.  Each wheel has a capacity starting from 60kg per minute and maximising at 1200kg per minute.  Companies need wheelblast machines where large parts or great areas have been derusted, descaled, deburred, desanded or if they need cleaning in some way.  Often the way to work out how to choose which process your business needs is based upon the size of the metal part that needs work doing to it – the ease of its transportation is the deciding factor.

Shotblasting and the Airblasting Process

Airblast machines are pneumatically accelerated machines which are air powered, with projected nozzles angled on to the component – the process, quite literally, is all in the name!  Airblasting can occur in two ways, either in a blastroom or a blastcabinet.  If special applications are needed, water mix can be used which is known as wet blasting.  Whether you need airblasting or wet blasting, the blast nozzles can be installed in to unique positions to target problem areas.  They can be operated manually or automatically or even by robots.

Shotblasting at NiTEC UK

Shotblasting at NiTEC can occur for component parts which weigh up to 20 tonnes.  Usually, the shotblasting process is required prior to our electroless nickel plating process, as a surface preparation, in order for you to gain the best finish and your metal components to get the best protection.  The better the abrasive finish from the shotblasting process, the better the electroless nickel plating, the better your component part will work and the longer it will last for you.  Shotblasting is an important process.

The Use of Electroless Nickel in Valves and Flow Control Devices

Electroless nickel is an excellent choice of surface technology for the oil and gas industry. As discussed in previous blog posts, the properties of elctroless nickel coatings are highly sought after in the industry, including corrosion resistance, uniformity of deposits and abrasion resistance.

Electroless Nickel and Mild Steel Ball Valves

electroless nickel plated valve ballsThese properties have resulted in the widespread use of electroless nickel coatings in valves and flow control devices, which are critical components in the operation of a well where good performance and long life are major economic factors.

The application of electroless nickel to mild steel ball valves is now typical in the oil and gas industry, replacing hard chromium as a corrosion resistant, smooth and uniform coating.

Successful applications of electroless nickel have been observed in all areas of the oil and gas industry. In crude oil production, mild steel ball valves have a maximum life of no more than three months, and fail due to corrosion, surface cracking and erosion. But valve components plated with electroless nickel last for years with no surface deterioration.

Similar benefits have also been observed on ball valves at plants using the sea water injection system which involves pumping sea water under high pressure to force oil to the surface. With a coating of electroless nickel, the valves withstand the conditions and no degradation is detectable after years of operation.
