Details Product
Performance Certificates Since 1972, with the introduction of Fluoropolymer coating in America, TEFCOTTM coated studs bolts and nuts are widely used for enhanced corrosion resistance, permanent thread lubrication and consistently low applied torque to induced tension (clamping load). Since then, almost all international petrochemical, oil drilling rigs and chemical process industries have specified these studs for both offshore and land based applications. Apart from these TEFCOTTM coated B7 stud, bolts are installed under sea splash zones and chemical environments with great success Test Results : [ 1 ] Acid Test [ 2 ] Caustic Test [ 3 ] Bromine Test [ 4 ] Salt Fog Test |

Properties:
Over a phosphate pretreatment, a TEFCOTTM system far exceeds in performance when compared with galvanised, cadmium plated, aluminised or molycoated studs and other premium types of studs. A TEFCOTTM coating prevents galling and reduces both 'make-up' and 'break-out' torques.  |
  Typical Application: The use of TEFCOTTM coated bolts is increasing in industrial applications, offshore, petrochemicals and marine industries due to their property of withstanding extreme corrosive environments and providing permanent lubrication over a very wide temperature range. |
