Pipeline Pigging, Standard Poly Pigging
Pipeline cleaning, pigging and descaling is an area of expertise that has particularly benefited from Tube Tech’s radical approach. Tube Tech manufactures and modifies pipeline pigging equipment to suit the consistency of deposits and pipe configuration. It can operate in tube and pipeline bores down to 2mm and as large as 1.5m. pigging and cleaning pipelines that previously were deemed unpiggable
Pipeline operators are facing immense pressure to monitor and maintain pipelines to ensure incidents effecting the environment become more and more rare.
Claiming a lack of budget or indeed a lack of technological development can no longer be used as reasons for a lack of inspection or a lack of a maintenance plan for pipelines. The cost of blockages and high levels of scaling causing immense back pressure on pumping equipment is far higher than any costs incurred for an inspection or maintenance campaign.
Traditional pigging often requires that all conditions are perfect, for example; pressure rating, no severe intrusions, weak joints, cracks etc. With pipelines getting older, diameters varying within the same pipe and many featuring bend restrictions and unfriendly T section fittings the perfect conditions can often be few and far between.
Tube Tech International are highly experienced in the traditional pigging of pipelines but, unlike other traditional specialist cleaning contractors Tube Tech are also able to ‘pig the unpiggable’.
A particularly successful Tube Tech innovation is the expandable pig or drift system capable of removing a variety of deposits from large diameter pipelines which can be loaded via a small aperture.
Tube Tech have designed innovative pigs for unusual applications (including studded pigs), which have unblocked pipelines that other contractors had deemed ‘uncleanable’ and have provided quick and cost effective solutions for the worlds leading pipeline owners.

Small Bore and Large Bore Pigging
The pigging of very small or large inaccessible and convoluted pipelines is an application which many specialist pigging contractors struggle with, never mind traditional cleaning contractors. Most specialist pigging contractors use ‘standard’ size pigs but then are unable to adapt their equipment to the specific and often unusual needs of a client for small or large bore pipelines with unusual or restricted access. In keeping with their ‘can do’ attitude Tube Tech have developed several unique systems to effectively pig hitherto impossible small and large bore pipelines where traditional pigging approaches have struggled.
The ability to pig smaller pipes, for example 4 mm to 75 mm diameter, is an area in which traditional pigging contractors can struggle. Pigging is an application often associated with large diameter pipelines and particular formulae yet small pipelines can also benefit from innovative pigging methods where formulae is replaced by initial instinct and then in depth trials.
Traditional pigs cannot be used when isolation valves or access is absent on T offs or launch areas – meaning the pigs can neither be inserted nor “steered” down the relevant lines.
Tube Tech has developed a unique pigging system which actually involves building the pig through a narrow restriction located on a much larger pipe. Tube Tech can even stop the pig at pre determined spots, even ay dead ends, where they can extract the pig via access points such as a flanged stab measuring as little as 1” diameter!!

Intelligent and Semi Intelligent Pigging
Innovation in the pigging industry has seen an increasing use of highly sophisticated sets of equipment which combine pigs with intelligent transmitters – the intelligent pig. These pigs are fitted with global positioning systems, internal cameras for live video feeds, tools to measure pipe thickness and pipe conditions.
Tube Tech have successfully managed intelligent pigging activities in Nigeria, Saudi Arabia and Turkey as well as the UK and the rest of Europe. Drawing on their vast experience the company has also applied intelligent pigs in a wide variety of situations ranging from oil, gas and lube oil pipelines to pipelines in the paint, chemical and foodstuff industries.
Tube Tech is able to facilitate many of your small diameter intelligent pigging needs. Tube Tech recognise the fact that intelligent and semi intelligent pigs require “very clean” pipes to inspect and are ideally placed to clean these pipelines prior to any intelligent pigging exercises no matter what the deposit whether wax, crude, coke or concrete. Tube Tech International Ltd will have a method to unblock and de-scale it.
