Industry Value Chain
The road / railway tankers or tank wagons market consists of tank wagons rail freight transportation services and related goods by entities (organizations, sole traders, and partnerships) that provide the transportation of freight in a tank wagon. Tank Wagons are designed to transport liquid and gaseous commodities on the rail transport system. Only goods and services traded between entities or sold to end consumers are included.
The global tank wagons market size is expected to grow from $63.4 billion in 2021 to $69.71 billion in 2022 at a compound annual growth rate (CAGR) of 10.0%. The tank wagons market is then expected to grow to $85.8 billion in 2026 at a CAGR of 5.3%. Increased demand for liquid and gases as a raw material in residential and petrochemicals sectors that use railways as one of the modes of transportation is contributing to the growth of the tank wagons market.
India is expected to buy 15.8 million tons of LPG from abroad in the 2020 year which is 9% more than in 2019. It is also estimated that the Asia region will buy 67-69.5 million tons of gas from abroad.
The main types of tank wagons include pressurized railroad tank cars and general-purpose or non-pressurized tank cars. The pressurized railroad tank car was designed to carry chemicals and petroleum products efficiently and safely. It is also segmented by protection type into insulated and non-insulated and by application into crude oil, ethanol, liquefied gases, biofuels, milk, chemicals, and others. Additionally, the increased rate of accidents due to the high speed of railways pose a major challenge to the manufacturing process of tankers.
Himalaya understands the needs of the road/railway tanker industry’s needs and have developed advanced design and engineering capabilities at our expansive manufacturing facilities that enable us to deliver efficient and precise solutions to the industry. Through 40+ years of experience and expertise of building plate bending machines, we have developed solutions that are targeted towards the safe and efficient manufacturing of tankers.
Tanker manufacturing requires high productivity, precision and ease of operation that Himalaya plate bending machines are designed to deliver.
Himalaya machines have a robust steel structure made from heavy metal plates, connected to each other by a strong box design chassis with interlocking frames & strengthening ribs. These allow for parallelism of all axes and precise surfaces, as well as longevity and precision.
We design the rolls with optimal diameter and use forged carbon steel rolls machined by high precision CNC lathes. Our rolls have a special spline-based design that is extremely efficient in connecting the rolls with the planetary gear system. Our rolls are also crowned to compensate for roll deflection during the bending process.
Our machines are equipped with a hydraulic system which can work at less than full capacity when jobs less than maximum thickness are rolled. Twin speed operation also reduces the energy consumption up to 50% at slower speeds.
Himalaya Planetary driving system used in our machines is efficient and eliminates energy wastage associated with heavy-transmission systems and yet achieves the goal of speed reduction by increasing the stages in gears and pinions.
The simple yet robust design of our machines also enables ease of operations and faster manufacturing. And our full package of accessories provides quick movement of rolled plates for rolling, welding, and subsequent manufacturing activities. The high construction quality of our machines means that they can work 24 hours a day and are highly reliable with minimum downtime.
The HIMALAYA Advantage
What is done to compensate for deflection of rolls during pre-bending and rolling?All rolls are crowned (cambering) for compensating deflection.
What is the arrangement provided for balancing of top roll when swing arm is opened?Top roll is counter balanced automatically once the drop end is opened without any jacks or manual arrangement.
Is there any method to know the position of bottom rolls?DRO (Digital Readout) is housed on the operating console which gives the position of the bottom rolls with respect to the top roll.
What is the capacity for cone bending?Cones can be bent up to the edge-bending capacity of the machine. The bottom rolls can be inclined for the required cone angle.
What is the level of protection for electrical components?Some of the electrical bough outs are IP 55 like motors, switchgears etc. The electrical cabinet will be manufactured as per our standard practices and will meet IP 55 protection.
Is the main drive reversible?Forward and reverse to the main drive is provided. The bottom rolls can be moved up and down individually.
What is the type of oil required?Hydraulic oil – Enklo 68 Planetary Gear box – EP 90
Where are the main machine controls?Operating console houses push buttons for all the operations of the machine. The console is movable so that the operator can keep it at any desired location.
Can we bend hot plates on the machine to get higher thickness capacity?Although the standard machine is not meant for hot rolling, occasional hot rolling can be done (a few jobs per month) provided that suitable precautions are taken.
Some plates have high yield point (YP). The rolling capacities are rated for 26Kg/mm2. How to find the equivalent thickness?Divide the Actual YP by 26. Find square root of this number. Multiply this value by actual plate thickness to get effective thickness.
Enjoy the peace of mind that you are in good hands.
