Steel Tubes
Division

Shaft tubes

Propeller shaft:

• High Strength Material (like SAE 1020)
• Can be subjected to high torsion and shear stress
• Light weight

Axle Shaft:

• Very High Strength Material, like St – 52 (As per DIN Std.)
• Good load bearing capacity, high torsional and shear strength

Side Impact Beam

• Increased crash safety and lower weight at reduced cost are nowadays among the most important requirements for body-in-white components. Side impact protection beams have to meet these requirements. Especially the use of ultra-high strength steel demonstrates to be an efficient approach to reach this target.
• To achieve this target, very high strength Boron treated material is used, later to be induction hardened to meet the specific requirement of ultra high tensile strength i.e. more than 1450 MPa as well as hardness along with nominal elongation i.e. 10%

Metal Tube Assemblies

Fuel Injection Tubes:

• Fuel Injection Tubes are used in large numbers in all kinds of diesel engines for automobiles, ships, construction equipment and agricultural machinery.
• These are manufactured using high grade materials like IF grade, which impart utmost level of durability.
• Flaring of more than 100% can be achieved.
• Tubes are strictly checked on the parameters of quality, dimension and cleanliness.

Hydraulic Tubes

• A qualitative range of Hydraulic Tubes.
• This precision engineered product possesses high tensile strength and is extremely durable.
• These tubes are used in Hydraulic applications in Automobile and other industries.

Heat Exchanger, Air Pre Heater and Boiler Tubes

Air Pre Heater Tubes

• Air heater tubes or APH tubes are used in sugar mills, heat exchangers, paper and chemical industry.
• Our Air Pre-heater Steel Tubes are manufactured from the superior quality materials like Corten Steel conforming to ASTM A 423 grade I. The tubes so made are annealed, fin (inside weld) is removed (fin-cut)
• They are pressure and hydro tested.

Boiler tubes

• Large assortment of precisely designed Boiler Tubes.
• High Pressure Boiler Tubes are manufactured from the premium raw materials like Grade 320, 360 and 440 under strict quality norms.
• Boiler Tubes are available in various sizes to match the requirements of the clients.

Other Applications

Bobbin Tube
