A 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. Shell & Tube heat exchanger 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 by several types of tubes: plain, longitudinally finned, etc. One phase heat exchanger Heat exchangers with only one phase (liquid or gas) on each side can be called one-phase or single-phase heat exchangers. Two phase heat exchanger Two-phase heat exchangers can be used to heat a liquid to boil it into a gas (vapor), sometimes called boilers, or cool a vapor to condense it into a liquid (called condensers), with the phase change usually occurring on the shell side. U-Type There can be many variations on the shell and tube design. Typically, the ends of each tube are connected to plenums (sometimes called water boxes) through holes in tube sheets. The tubes may be straight or bent in the shape of a U, called U-tubes. 1-pass straight-tube heat exchangers Surface condensers in power plants are often 1-pass straight-tube heat exchangers. 2-pass straight-tube heat exchangers 2-pass designs are common because the fluid can enter and exit on the same side. This makes construction much simpler.

With increasing stringent security rules and regulations, security cabins have become a must in all gated communities, commercial buildings, malls, industries and factories. They also protect them from the hot sun and stormy weather conditions. at karthick industries, security cabins are manufactured using high quality raw materials. They are spacious and can be built on the specified dimensions provided by the customer. security office options exterior colour interior colour quantity of windows / doors position of windows / doors fixed windows opening windows electrics floor covering fork-lift pockets window shutters shelving air conditioning

Applicable to all common non flammable refrigerants including R717 and non corrosive gases/liquids dependent on sealing material compatibility. no special flow direction required. valve safety is enhanced with the spindle being secured such that it cannot be unscrewed.

A spirally coiled finned tube heat exchanger made of a copper finned tube with medium high ribs, tin-plated exterior incl. screw connection. The pipe connections are hard-soldered to the pipe ends. These are manufactured at M/S Karthick Industries on specially developed high speed finning machines. finned tube heat exchanger Our machines are capable of finning tubes around a length of 12 m to 18 m (60 feet). We make finned tubes with base tubes of carbon steel, stainless steel, copper and copper alloys like CuNi ( copper-nickel), admiralty brass, aluminum brass and copper tins, galvanized iron tins. We do the OD of the tin tube from 16mm to 120 mm ranging from 3mm to 16mm. Currently we manufacture finned tin tubes with 4 FPI to 12 FPI (as per customer’s requirement).

We are offering safety relief valve a valve which relieves pressure beyond a specified limit and recloses upon return to normal operating conditions. A pressure-control valve in any fluid system, which limits the pressure in the system by releasing it at a preset value. The pressure is not allowed to be built up above this preset figure. self actuated pressure control valves without any need of external power or air supply. Body cs/ss/ci and the internal should be in ss grade. sizes: 1/2" ,3/4" , 1" , 1 1/2" , 2" screwed type, 1", 1 1/2", 2", 3", 4" flanged type with ptfe, neo-prene, phosphor bronze.
