Twisted Tube™ Heat Exchanger Cleaning

Twisted Tube™ Heat Exchanger Cleaning – Shell and Tube Side

Recognised as a challenging task, Twisted Tube™ Heat Exchanger cleaning is a specialist cleaning challenge which Tube Tech International has frequently solved.

The unusual design of Twisted Tube™ Heat Exchangers means that traditional cleaning techniques such as standard high pressure water jetting and standard chemical cleaning cannot remove all of the deposit gathered within the tube and shell side of the exchangers.

Twisted Tube™ Heat Exchangers generally have 40% higher Heat Transfer contemporary for the same pressure drop as Conventional Shell & Tube Heat Exchangers. Twisted Tubes support themselves, so baffles are not needed. As the tubes are supported by various contact points, decreasing the turbulence results in no dead spots and with faith that fouling will be diminished.

Shell Side Fouling and the Tube Side deposits can be troublesome to eliminate using Traditional High Pressure Water Jetting or Chemicals. These Exchangers accommodate ‘cleaning lanes’. However, the task of cleaning can be laborious if blocked with deposits.

Tube Tech International presents an exceptional cleaning approach for Shell Side Twisted Tube™ Heat Exchanger Cleaning. Tube Tech also uses remote technology that fully progresses through the cleaning lanes and channels, infiltrating the scale and also abolishing all blockages within the Tube Bundles. Twisted Tube™ Heat Exchanger Cleaning on the twisted tube bore is executed by using a technology that expands during cleaning to the diameter and Tube Twist configuration.

Texas Tower Cleaning (VCFE)

Texas Tower Cleaning (VCFE)

With low emissions, minimal environmental impact and high energy efficiency the The Vertical Combined Feed Exchanger (also known as a CCR Platformer, reformer or Texas Tower) is an environmentally friendly piece of heat transfer equipment found on refining and petrochemical plants throughout the world. The function of the Texas Tower process is to efficiently convert paraffins and naphthenese to aromatics with as little ring opening or cracking as possible.

As a clean exchanger, The Texas Tower need only be cleaned every 7 – 10 years (minimum), upholding a steady and high grade performance. Problems can occur when its performance does start to fall; this is a gradual procedure that usually goes unnoticed.

As a very clean heat exchanger, the lack of knowledge regarding Texas Tower Cleaning (due to its absence of the need to be cleaned), means operators can become worried on who to ask for advice on how to clean them. Standard Cleaning Contractors will not usually have experience of Texas Tower Cleaning

The challenges for refineries and petrochemical operators when faced with a fouled Texas Tower or indeed any unusually long exchanger are numerous. Challenges include accessibility, safety, unknown fouling characteristics, fouling location, associated costs and risks with pulling.
Since Texas Towers are cleaned so infrequently it is essential that when they are taken off line for cleaning they are cleaned fast, safely and most importantly effectively with the “right methods”.  Operators need to challenge their industrial cleaning contractors constantly and particularly when the heat transfer equipment is critical path. Texas Towers are difficult to clean but building mock ups, using 3D animations to demonstrate techniques and arriving on site with a number of back up techniques has led to Tube Tech Internationl becoming a worldwide ‘expert’ in the cleaning of these huge structures.

Heat Exchanger CleaningAdvanced Techniques to Remove Shell Side Fouling

An essential contribution towards efficiency maintenance and the reduction of running cost is keeping plant equipment free of debris. Cleaning of the External Shell Side needs to be conducted frequently, but can initiate further problems if heat exchanger cleaning is done inaccurately.

The deviances of maintaining cleanliness of a Heat Exchanger are subject to the application. Sticky layers of Polymer are left behind by certain cleaning processes, whilst others construct solid deposits which require particular cleaning techniques. Ultra-High Pressure Water Jets are used to clean The External Shell Side within Heat Exchangers.

The deposits can cause extreme problems when done wrongly, as they can group together in areas that are harder to reach and can create bigger and harder cleaning tasks. This can then lead to devastation and damage of the Heat Exchanger.

Heat Exchanger Cleaning - External Side

Cleaning the External Shell Side must be met in a two-stage movement. It is vital to canvass the tube bundles and shell sides pre and post cleaning. This will help establish that all debris is removed without damage. Specialist cameras must be enforced where internal cleaning is restricted / impossible to ensure that debris has been effectively extracted.

TubeTech sufficiently engage in External Shell Side Cleaning of Heat Exchangers by applying their advanced ‘ShellJeTT™’ cleaning technology. This appliance has contributed to many industrial businesses. In conjunction with this, their exclusive ‘BladeSpec™’ Inspection System (one of the thinnest investigation cameras in the world) is also offered by TubeTech.
