Eddy current testing is a non-destructive testing method widely used to examine tubing in heat exchangers steam generators condensers air coolers and feedwater heaters Eddy current testing of tubes is an effective way of assessing the condition and lifespan of tubes particularly in the power generation petrochemical chemical fertilizer Pipe Cleaning and Coating - IOS Inspection IOS offers these services for used drill pipe up to 10 inches in diameter Cleaning involves the removal of loose internal coating scale foreign matter and other debris from the ID or OD of the pipe After cleaning we can provide an internal coating of corrosion inhibitor Free Chat

Heat Exchanger Cleaning - GoodwayJust a light coating of scale can drastically reduce the heat exchange properties of your tubes using more power and creating more wear and tear on your system Goodway offers rotary tube cleaning systems and heat exchanger chemical descaling solutions

Start studying 3rd Class Power Engineering - B2 - Part 1 Learn vocabulary terms and more with flashcards games and other study tools - Cooling water is circulated through small diameter tubes while steam acts on the outside of the tubes - Steam and water directly contact and the steam condenses - Ejector condensers are good for

such small concentrations may be difficult or uneconomical to control by another technology or even by all adsorbents Incinerators membrane separators and condensers may be economically feasible when used in place of adsorbers at the upper end of the range In addition to emission control the adsorber makes recovery of the VOC possible

Syngas Production In what is called steam methane reforming high-temperature steam (700Cā€“1 000C) is used to produce raw syngas from a methane source typically natural gas Using a steam methane reformer (SMR) methane reacts with steam under 3ā€“25 bar of pressure in the presence of a catalyst to produce hydrogen carbon monoxide and a

Tube Cleaner Shafts Brushes Accessories

Dual diameter spin grit brushes are coated with a specialized grit Recommended for removing soft and light scale deposits For straight ferrous and nonferrous internally enhanced tubes For tubes 1/2-1-1/4 (12 7-32mm) I D Quick Connect and threaded options Flexible Shaft Wet Tube Cleaning Nylon Casing for Tube I D 1/4-3/8

Improvements in tubes which increase the heat exchange capacity of tubular heat exchangers using the tubes are described These improvements involve the use of one or more external surface enhancements optionally combined with an internal enhancement and/or differing tube geometries These improvements apply for example to internal condensers including those in which the tube

Fouling in Heat Exchangers 59 heat flux is high as in steam generators fouling can lead to local hot spots resulting ultimately in mechanical failure of the heat transfer surface Such effects lead in most cases to production losses and increased maintenance costs

A small bypass valve is usually used to permit a small continuous flow of steam to keep the steam holes open and permit smokeless burning of small gas flows Ground-level flares are of four principal types: horizontal venturi water injection multijet and vertical venturi

Brushes have also been effective in cleaning tubes with enhanced internal surfaces (spirally indented grooved or finned) or tubes with thin metal inserts or epoxy type coatings However the presence of sharp bends in small diameter tubing

The exhaust steam enters the condenser through the top of the shell where it strikes the steam baffle plate which spreads the exhaust steam throughout the condenser As the exhaust steam passes downwards around the hundreds of small tubes it is condensed into water by coming in contact with the cold tubes

A pneumatic launcher propels the projectile sized slightly larger than the internal diameter of the tube into the tube where it removes the contamination deposited on the internal tube surface and forces it out of the tube Tubes with internal diameters from 2 mm

Improvements in tubes which increase the heat exchange capacity of tubular heat exchangers using the tubes are described These improvements involve the use of one or more external surface enhancements optionally combined with an internal enhancement and/or differing tube geometries These improvements apply for example to internal condensers including those

Description: Our 50 years of coating history speaks for itself In 1964 Heresite was the first company to apply coatings to aluminum-finned copper-tubed heat exchangers and radiators The Heresite coating became then and still remains a standard in the industrial coatings industry

Double-pipe heat exchangers are built in modular concept i e in the form of hairpins 1 4 1 2 Shell-and-Tube Heat Exchangers Shell-and-tube heat exchangers are built of round tubes mounted in large cylindrical shells with the tube axis parallel to that of the shell

Condensation of steam or water vapor is effected in either steam condensers or dehumidifying coils and the resulting water is called condensate CONDENSE - Action of changing a gas or vapor to a liquid CONDENSER - An apparatus used to transfer heat from a hot gas simultaneously reducing that gas to a

The method for making cold-drawn seamless pipes involves taking a round 'billet' or bar of steel and boring it in the center turning it cutting it heating it to make it more pliable then 'drawing' it (extruding or pulling it) to make it a longer and thinner tube
