BTFLN WAGON

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.).

A BREAK THROUGH TECHNOLOGY The newly designed tank barrel is inclined at

1 deg towards discharge points to facilitate

easy flow of POL Products.

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.

A BREAK THROUGH TECHNOLOGY

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.

The newly designed tank barrel is inclined at 1 degree towards discharge points to facilitate flawless, easy & quick

discharging of POL Products.


There were no cost overrun or time overrun. Quality of this wagon was of very high standard resulted in no customer complaint.

OPERATIONAL EXCELLENCECOST – QUALITY-TIME

250 Wagons have been manufactured and despatched with last consignment on 30th September’2012. Because of operational excellence, Railway Board has given repeat order of 480 Wagons which is under execution.


This wagon is having the advantage of carrying 7% more POL Products as comparison to its predecessor BTPN Wagon. This resulted in cost advantage for Indian Railway.

SELF RELIANCE OF INDIA IN RAILWAY SECTOR

This wagon is designed to run at higher speed than BTPN Wagon resulting in less transportation time cycle.


This wagon is designed with advanced and faster loading and unloading system resulting lesser haulage time.


This wagon is equipped with state of the art Bogie Mounted Brake System (BMBS) which is an advanced braking mechanism. This increases more safety factor.


The design of this wagon is in compliance with European and American Standard for Tank Wagon. As it has already been a tested product hence no foreign support is required.
