Based on pipes made in special technology, along with a broad range of fitting elements and accessories which make every type of connection possible, Tweetop PERT is a complete installation solution.
Tweetop PERT system offer includes pipes and fittings in 16 - 75mm diameters with a set of essential accessories and installation tools dedicated to specific applications of the system.
Tweetop PERT system based on multilayer pipes joined by pressed connections is currently one of the most advanced and innovative solutions available on the market. This is determined by two factors - the construction of the pipes and the connection technology. Tweetop PERT pipes have a multilayer structure - their core is made from an ultrasonically welded aluminium pipe. After adding two layers of the raised temperature polyethylene (PERT) material to the inside and outside of the aluminium pipe, we obtain a multilayer pipe capable of simultaneous work under the influence of pressure and temperature rated at 10 bar and 95°C. This unique combination of plastic material and the conventional aluminium insert allows Tweetop PERT pipes to keep the advantages of both, traditional and plastic pipes while eliminating their disadvantages.
Tweetop PERT system is ideal for both new investments and renovations of old installations in residential, public and historical buildings.
Tweetop PERT system pipes are manufactured of plastic raw material known as raised temperature polyethylene
To put it very simply, the structure of this material is similar to balls of wool which are merged mutually with side threads, resulting in a structure that is very tangled but very strong and difficult to break. When it comes to pipes, this translates into high resistance to temperature and pressure, which is so important in plumbing and heating systems.
Comparison of structures for Tweetop PERT material and standard plastic materials
The foundation of Tweetop PERT system is based on multilayer pipes consisting of:
Tweetop system pipes offer a unique combination of the advantages of plastic and metal, while eliminating the drawbacks of these materials.
Cross-section of Tweetop PERT multilayer pipe
System components are connected with three types of fittings.
The specificity of joints within the Tweetop system is based on the technology of pressing, consisting of mechanical fixation of plastic with fitting brass. These types of joints are:
Cross-section of Tweetop PERT pressed connection
Pressed connections are performed using a manual or electric pressing tools, equipped with U profile clamping jaws. Connections should be preceded by chamfering of pipe's inner surface using Tweetop bevelling tool .
Fittings of this type are necessary when making connections with Tweetop PERT system manifolds and radiators (they have an Euroconus chamfer type). To perform the connection following tools are required:
Connector core type fitting
Fittings of this type are useful for surface-mounted installations - connections with press-screw type fittings are considered to be separable and as such can not be used on installations carried beneath the floor or plaster surface.
This type of connection is very similar to the one using connector core type fittings. The only difference is in the type of fittings chamfer, which in this case is typical for water systems.
Press-screw fitting
Tweetop provides insurance for up to 4 million PLN in STU Ergo Hestia for the Tweetop PERT system pipes.
The insurance policy is issued for a specific object on which certain Tweetop products were used. The policy has an individual number and information about the beneficiary of compensation. Tweetop Sp. o.o. bears all costs associated with the issuance of the policy.
Following conditions should be followed to claim the policy:
