hese Seamless Tube mainly find applications in Pressure Vessels, Cryogenic Pressure Vessels, High pressure Equipments, Tube Sheets of Heat Exchangers, Boilers, Air Pre Heater, Finned Tubes, Air Cooler Tubes, etc. They are used in Industries like Refineries, Power Plants, Steel Plants, Chemical Factories, Fertilizer plants, and Ship Building etc.

U Tubes are manufactured after the Straight Tubes are manufactured. The Bending is done in Cold State on an Automatic U Bending Machine. To ensure that wall thinning and diameter ovality are kept in control, bending of tubes Is done with a mandrel inserted in the tubes. Furthermore the U - Bend portion of the U-Tube is Stress Relieved in controlled conditions and cycle to give longer life.

The U bent tubes are finally 100% Tested for Hydrostatic Leak Test and then finally DP tested. These tubes are vulnerable to getting damaged in transit and hence are required to be handled with care. We ensure this by packing tubes in specially designed steel frames. These frames are fit into the wooden box o further ensure safety of the tubes.

The bending of the tubes is carried out in respect to various international standards like :

TEMA RCB 2ASTM A 556 / ASME SA 556
AS PER CLIENT DRAWING  

We can manufacture U Bend Tubes with Minimum Bending Radius of 1.5 D and Maximum Up to 1500mm.

Hydraulic tubes are seamless steel precision pipes, specially manufactured for hydraulics. The tubes have standard sizes for different pressure ranges, with standard diameters up to 100 mm. The tubes are supplied by manufacturers in lengths of 6 m, cleaned, oiled and plugged. The tubes are interconnected by different types of flanges (especially for the larger sizes and pressures), welding cones/nipples (with o-ring seal), several types of flare connection and by cut-rings. In larger sizes, hydraulic pipes are used. Direct joining of tubes by welding is not acceptable since the interior cannot be inspected.

Hydraulic pipe is used in case standard hydraulic tubes are not available. Generally these are used for low pressure. They can be connected by threaded connections, but usually by welds. Because of the larger diameters the pipe can usually be inspected internally after welding. 

Hydraulic hose is graded by pressure, temperature, and fluid compatibility. Hoses are used when pipes or tubes can not be used, usually to provide flexibility for machine operation or maintenance. The hose is built up with rubber and steel layers. A rubber interior is surrounded by multiple layers of woven wire and rubber. The exterior is designed for abrasion resistance. The bend radius of hydraulic hose is carefully designed into the machine, since hose failures can be deadly, and violating the hose's minimum bend radius will cause failure. Hydraulic hoses generally have steel fittings swaged on the ends. The weakest part of the high pressure hose is the connection of the hose to the fitting. Another disadvantage of hoses is the shorter life of rubber which requires periodic replacement, usually at five to seven year intervals.

Part TypeExchanger Tube

shell and tube heat exchanger is a class of heat exchanger designs.It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed of several types of tubes: plain, longitudinally finned, etc.

Seamless pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless Steel Pipe is made from a solid round steel which is heated and pushed or pulled over a form until the steel is shaped into a hollow pipe. The hollow pipe is then extruded through a die and mandrel combination to reduce the outside diameter and to expand the inside diameter.

In systems involving heat transfer, a Condenser is a device or unit used to condense a substance from its gaseous to its liquid state, by cooling it. Condensers are typically heat exchangers which have various designs and come in many sizes

There are many various types of Condensers, typically differentiated on their medium of Heat Exchange. Like Air-cooled Condenser, Water Cooled Condenser, Evaporative Condenser. However, in all types of Heat exchanger tubes and Condenser Tubes play one of the most Vital Roles in the process of Heat Exchange. The Condenser Tubes can be used in various forms such as Straight Condenser Tubes, U -Tube Condenser Tubes ( U bend ) , Spiral or Coiled Condenser Tubes , Finned Condenser Tubes etc.

Extruded Fin Tubes are heat exchanger tubes mainly required to transfer heat from a flowing fluid and cooling it down by passing air on the fins of the tubes. In extruded fin tubes the surface area of heat transfer is increased because of the increased height of the fins thereby causing it to become more exposed to the flowing air. Moreover in this process the thickness of the fin is also very low causing the heat transfer to become more efficient. The extruded fin tubes are used mainly where the atmosphere is corrosive and the heat transfer required is higher.

Extruded fin tubes are mainly manufactured by extruding fins from the base material itself. It is generally manufactured using bimetallic combinations where the base tube can be made of Carbon Steel, Alloy Steel, Stainless Steel, etc and the fin material is Aluminum or Copper etc.

In the process of manufacturing Extruded Fin Tube, a Muff Tube (Outer) and a Base tube (Inner) are used. The base tube is inserted inside the muff tube. Then the fining is done by extruding the fins from the Muff Tube. During the process the muff tube forms a very strong bond with the Base tube ensuring almost no air gap or non contact area between the Muff Tube and the Base Tube.

There is 100 % contact between the Base and the Muff Tube in Extruded Fin Tubes. This increases the surface area and gives the best heat transfer.

  • In Extruded Fin Tubes, Aluminum Muff Tube covers the Base tube completely and hence gives excellent corrosion protection to the Base tube. This increases the life of the overall equipment and hence reduced downtime with greater efficiency.
  • In Extruded Fin Tubes, the fins are made by Extrusion process and hence have higher strength and resistance to damage my mechanical handling.
  • It s highly suitable for temperatures as high as 300 Deg C.
  • In Extruded Fin Tube, the bonding between the fins and tube is the strongest in the process.
  • During the manufacturing process no damage is done to the base tube and hence it increases the safety and quality of the final product to a great extent.
  • These Extruded Fin Tubes are manufactured by us on State of the art fining machine and can be supplied in the most efficient way. Special processes have been defined to ensure proper safety after packing of tubes.

    The main application of these Extruded Fin Tubes is in Air Fin coolers especially in highly corrosive atmospheres and high temperature applications.

    We can provide you the best quality Extruded Finned Tubes. We wait for your valued enquiries
