  6. 6. HYDRAULIC TEST OF BARREL   The barrel complete with internal fittings including Master Valve & Bottom discharge Valve after being mounted on the under frame shall be tested HYDROSTATICALLY to pressure 2.8 Kg / cm. sq. against leakage of longitudinal and circumferential weld seams of Barrel along with fitted valves. The pressure is maintained for 30 Minutes (min.).
  7. 7. A BREAK THROUGH TECHNOLOGY The newly designed tank barrel is inclined at 1 deg towards discharge points to facilitate easy flow of POL Products.
  8. 8.  The wagon is manufactured from: ◦ SAILMA 350 ◦ IS: 8500 Fe 570B These high strength micro alloyed steels have higher yield strength, higher notch toughness, good fatigue properties, excellent weld ability and good formability.
  9. 9. HUCK BOLT – FASTENING SYSTEM     Heavy duty applications demand tough, reliable fasteners. For application ranging from RAIL WAGON to MINING EQUIPMENT, HUCK BOLT fastening system offers superior vibration resistance and overall durability. Low cost fastening system. Extraordinarily low installation time. Safe, Worker friendly & above all Environment Friendly.
  10. 10. TEE SECTION DESCRIPTION BTFLN BTPN (conventional) TEE SAILMA 350 GRADE STEEL X NEWLY DESIGNED ‘TEE’ ABOLISHES FULL LENGTH UNDERFRAME OF CONVENTIONAL WAGON. DIRECTLY IMPACT THE HIGHTENING PERFORMACE OF WAGON.
  11. 11. CENTER SILL DESCRIPTION BTFLN BTPN (conventional) CENTER SILL SAILMA 350 GRADE STEEL IS: 2062 Fe410 CuWA GRADE STEEL ADVANTAGE: SAILMA 350 MICRO ALLOYED STEEL RESULTS ENHANCED PERFORMANCE & DURABILITY. NEWLY DESIGNED CENTER SILL IS SHORTER IN LENGTH – THAT RESULTS LEGHTER WEIGHT & INCREASES THE CARRYING CAPACITY.
  12. 12. BOLSTER DESCRIPTION BTFLN BTPN (conventional) CONTACT SURFACE AREA OF BOLSTER (TOP & BOTTOM) MORE LESS ADVANTAGE: MORE CONTACT AREA MEANS HIGHER BEARING CAPACITY THAN ITS PREDECESSOR ‘BTPN’ WAGON
  13. 13. SOLE BAR DESCRIPTION BTFLN BTPN (conventional) SOLE BAR SAILMA 350 GRADE STEEL IS: 2062 Fe410 CuWA GRADE STEEL ADVANTAGE: SAILMA 350 MICRO ALLOYED STEEL RESULTS ENHANCED PERFORMANCE & DURABILITY. STEEL SECTION IS LESSER THAT IT’S PREDECESSOR ‘BTPN’ WAGON – THAT RESULTS LEGHTER WEIGHT & INCREASES THE CARRYING CAPACITY.
  14. 14. UNDER FRAME    FRAMELESS UNDERFRAME DESIGNED TO LOW WEIGHT & HIGHER PERFORMANCE. MANFACTURED FROM SAILMA: 350 MICRO ALLOYED STEEL.
  15. 15. BOGIE MOUNTED BRAKE SYSTEM       IMPROVED BRAKING EFFICIENCY. LESS NUMBER OF PARTS – REDUCED WEIGHT UNIFORM SHOE WEAR & WHEEL WEAR. INCREASED RELIABILITY. EASY MAINTENANCE. VERY EASY TO ASSEMBLE – REDUCED INSTALLATION TIME.
  16. 16. BOGIE MOUNTED BRAKE SYSTEM     ONE OF THE MOST MODERN BRAKE SYSTEM. INTEGRATED DOUBLE ACTING SLACK ADJUSTER. MAINTAINS A CONSTANT STROKE. EASILY ADJUSTABLE ON WAGON.
