What is a bundle puller?

The Aerial Tube Bundle Extractor is a self contained unit, which is easily lifted into position by just one crane and can be operated by remote control. Because the unit is equipped with a small diesel engine, it can work independently at any place.

What is bundle 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 of several types of tubes: plain, longitudinally finned, etc.

What is bundle diameter in heat exchanger?

“D” Bundle Diameter – This is the overall diameter required to fit the bundle in an existing shell or tank. This dimension includes any baffles or tube supports. A good way to get an accurate “D” diameter is to measure the circumference and divide by 3.14. This gives you the diameter of the bundle.

What is a tube bundle heat exchanger?

Tube bundles are found inside shell and tube heat exchangers. The tube bundles are positioned within a cylindrical shell, where fluids at different starting temperatures pass through and over tubes. The fluids can either be liquids or gases.

What is a tube bundle?

A tube bundle is a set of tubes in a shell-and-tube heat exchanger. A set of tubes is called the tube bundle and can be made up of several types of tubes. In a shell-and tube-exchanger the tube bundle is enclosed in a cylindrical shell, through which the second fluid flows.

How do you maintain a heat exchanger?

Maintenance of fouled tubular heat exchangers can be performed by several methods such as acid cleaning, sandblasting, high-pressure water jet, bullet cleaning or drill rods.

What is AES type heat exchanger?

AES/AET- These units are the most expensive of the removable bundle designed units. The floating head is internal to the shell. Tubes can be cleaned mechanically , chemically, water blasted or steam cleaned.

Why floating head is used in heat exchanger?

The tubesheet at the rear header end of the shell is of slightly smaller diameter than the shell, allowing the bundle to be pulled through the shell. The use of a floating head means that thermal expansion can be allowed for and the tube bundle can be removed for cleaning.

How do you calculate bundle diameter?

Divide the circumference by 3.1415 (pi). This will give you the diameter of the cable bundle. For the diameter of the hole, add a quarter of an inch to this number.

Which type of heat exchanger is used for handling corrosive fluids?

Glass Heat Exchangers Are an Option for Handling Highly Corrosive Media. The process industry has used glass heat exchangers for years as a corrosion-resistant option for handling sulfuric acid. Glass heat exchangers offer an exceptional degree of corrosion resistance.

Why bundle pull heat exchangers?

Our bundle pulling system makes easy work of, heat exchanger extraction, lifting and final pushing the heat exchangers back into their shell once the maintenance or cleaning is completed. This ensures our customers the fastest, safest and most cost effective heat exchanger handling service.

What is the pulling force of an Ormonde bundle puller?

The Ormonde bundle puller has a 60 ton pulling force, making for easy and safe extraction of your heat exchanger out of its shell without putting any stress on the heat exchanger, the housing or the attached technology.

What is the purpose of a bundle extractor?

The Bundle Extractor or bundle puller procedure is the first phase of one of the four processes for maintaining the heat exchanger, which has as its purpose the output of the tube bundle from its shell. This first step is done by means of ad hoc machines called tube bundle extractors.
