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.

flare line cleaning

Flare Line Cleaning

In-situ and On-line Flare Line Cleaning

Flares are crucial safety devices used within the refining and petrochemical industries. During flaring excess hydrocarbon gases are mixed with steam and/or air to create water vapour and carbon dioxide.

Flare lines are often difficult to access as the flare line system often comprises a complex of pipework passing through the whole refinery or petrochemical plant. Much of this pipework is suspended on gantries about 4.6 m above ground making the logistics of flare line cleaning.

Safety is a key concern during every specialist industrial cleaning contract. Pyrophoric iron sulphide, hydrocarbon condensates and gases in the line present a risk of fire and explosive chemical components means that no oxygen can enter the flare line system and no gas can escape during flare line cleaning.

Created by Tube Tech International, their bespoke seal copes with Temperatures and Pressures inside ‘Flare Lines’, prohibiting Oxygen and Spark ingress and the release of toxic gases. The next step is then cleaning, accomplished by high-pressure jetting lances, constructed to be heat and scratch resilient when introduced into small entry points on the Flare Line.

Secure video probes for Visual Analysis are used to relay images post and pre cleaning. Tube Tech cultivates a Video Archive of intelligence on Flare Line Cleaning. They are fully able to exhibit their cleaning capabilities of Flare Lines anywhere on the globe.

Heat Exchanger Cleaning

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.

IRIS Inspection – Enhanced Cleaning Techniques

Guaranteed* Tube Cleaning Ready for IRIS Inspection Standard

The International Rotational Inspection System or ‘IRIS’ (an ultrasonic engagement pulse echo analysis technology), administers an exceedingly detailed inspection conclusion. Its performance towards this is gained by its tube dimensions and cleanliness. It can detect a 1.5mm irregularity in tubes up to 1 inch in diameter.

IRIS is compatible with both Ferromagnetic and Non-Ferromagnetic tubes, implementing a three dimensional image of the irregularity. Tubes should be clean for a successful IRIS inspection.

Offering its Enhanced Cleaning assistance, Tube Tech International are able to present an unmatched service to clients in search of cleaning tubes. IRIS’s flawless ultrasonic features will only work to an upstanding degree if the tube itself is completely clean. IRIS is used to inspect, drill, polish and de-scale tubes through even the minimalist diameter nozzle.

Operators are often faced with the following scenario:

  • Cleaning contractors clean heat transfer equipment tubes
  • IRIS inspection company arrives to inspection tubes
  • Tubes are not clean enough for IRIS inspection
  • Cleaning contractors have to return to clean tubes again
  • IRIS inspectors asked to return to hopefully successfully inspect tubes

Tube Tech’s guaranteed enhanced cleaning for IRIS inspection reduces the above by three steps i.e. tubes are cleaned ready for IRIS inspection the first time, thus saving operators both significant amounts of time and significant sums of money.

Contact Tube Tech International today to discuss your next tube cleaning contract.
