“Blinex also offers a comprehensive range of high tensile fasteners (B7/2H, B7M/2HM) in order to meet various industrial requirements.” Mr. Kirtan R. Dhami, Director (Technical & Exports) – Blinex Filter-Coat (Pvt.) Ltd.

Blinex Filter Coat Pvt. Ltd. is one of the pioneers of Teflon/ Xylan/ Halar / PTFE (Poly Tetra Fluoro Ethylene) coating and linings on industrial components, fasteners used in offshore and valve industries, textile rollers machinery parts, food / bakery moulds, chemical / pharmaceutical industries reactor vessels, valves etc. with foreign technical know-how and corrosion protection and resistant products and services for the oil, gas, petrochemical, power, marine industries and offshore industries.
 
Products:
Fluoropolymer (PTFE) / Teflon / XYLAN Coated Fasteners, Studs, Nuts, Bolts, Washers best suited for installations in offshore platforms, petrochemical and chemical plants, installations near the sea and in corrosive environments.
 
The company offers PTFE and XYLAN coated fasteners which are high on demand list in the market that contain PTFE or other types of lubricants.
 
The coating of Teflon / XYLAN provides effective solution to the problems in engineering construction regarding wrong surface properties arises.
 
Moreover, the XYLAN / Teflon is used as a coating material on alloy steel fasteners, aluminium and copper fasteners owing to various features including:
•      Nonstick
•      Low coefficient of friction
•      Heat resistance
•      Unique electrical properties
•      Polyurethane
•      Cryogenic stability
 
This range of products includes:
•     Nuts
•     Bolts
•     Washers
•     Threaded bars and many more
 
These high tensile fasteners are widely used in various industrial applications. These fasteners are available in various sizes, models, designs and finishes that sufficiently meet the client’s requirements:
•     Type: bolts, nuts, studs, washers, u bolts, j bolts, anchor rods, pins.
•     Size range: M 12 to M 150.& 1/2” to 6” length upto 1000 mm
•     Specifications: IS (GR.8.8, 10.9, 12.9,) BS (GR. R,S,T), ASTM A193 (GR.B7 / B7M), ASTM A320     
 
Apart from these TEFCOT coated B7 stud, bolts are installed under sea splash zones and chemical environments with great success
 
Various Test’s are undergone on PTFE/ FLUOROPOLYMER – TEFCOT coated Studs, Bolts & Nuts
•     Acid test subjected to 720 hours
•     Caustic test subjected to 12.5 ph caustic for 720 hours
•     Bromine test exposed to Bromine solution for 720 hours
•     Salt fog test subjected to 720 hours
 
Comparisons with other Coatings
Black, cadmium plated, and hot dipped galvanised bolts will freeze when subjected to the corrosive environments found in manufacturing plants, offshore oil rigs etc. Most often removing the nuts requires a cutting torch.
 
With BLINEX Fluoropolymer coating, the same nuts and bolts exhibit easy on and easy off characteristics increasing worker safety. Cadmium plated and hot dipped galvanised bolts provide similar corrosion resistance. These coatings have undergone the standard salt fog test (ASTM B117) and have been rated at 96 hours of corrosion resistance.
 
With a BLINEX Fluoropolymer coated bolt that rating jumps to as much as 1,000 hours. The additional corrosion resistance allows fasteners to be disassembled quickly, saving lost down time and man-hours.
 
Galvanising produces a coating that is uneven, rough and thick. The rough surfaces make assembly difficult and a tight even tension on each bolt impossible. If used in sealing joints such as flanges, heads or inspection covers, the inconsistent tension forms an uneven fit resulting in a high probability of leaks. With a BLINEXTM Fluoropolymer coated bolt, tighter more consistent tensions are achieved with less required torque.
