Pipes for Partizansk within 14 days
Pipes delivered to Partizansk within 14 days
Our persistent customers from Primorskiy Kray won a bidding procedure for construction of a new heating boiler plant and a heat supply utility for a residential community in Partizansk City. They addressed us with a ready solution and a well-developed design. The schedule was very tight with 3 months for everything, beginning with the delivery of the pipes to the project site and finishing with putting the utility in operation.
There is a big problem our customers form the Far East encounter, being the long delivery times. Sometimes, they have to wait 3-5 weeks before the materials and the components arrive. To avoid the long waiting times, we addressed our partner, "TransContainer" TK who arranged and dispatched an express train with the pipes. As a result, the order was delivered within 14 days only.
Initial conditions
- 2,094 m utility length;
- 325х1 mm required pipeline diameter;
- non-accessible service ducts. During the pipe selection, it was important to minimize the risk of emergencies since occurring failures are complicated to handle;
- type of installation: underground routing. It had to be considered that directly buried pipes experience negative impacts of stray currents and groundwater leading to corrosion;
- soil frost depth 1.34 m.
Heat supply utility configuration
The customer had two options to choose from:
- Steel seamless pipes with external protection in form of mineral wool cylinders and bitumen mastic waterproofing, or
- ЛPipes with prefabricated PUR foam insulation in PE jacket.
After a comparative study of technical specifications, the customer made the choice in favor of PUF PE pipes.
Why did the customer choose PUF PE pipes?
- the insulation performance of the mineral wool gets reduced in the course of the operation, so that up to 30% of the total heat gets lost, whereas PUR foam loses only 3%;
- the PE jacket is more reliable than the bitumen mastic, and protects the pipe against electrochemical corrosion due to stray current and ground water. It is stipulated by the factory-made tight structure. When protective coats are made in-place, it is not easy to achieve a uniform layer, not to mention that it slows down the installation progress;
- based on the statistics of our foreign colleagues, PUF PE pipes remain tight within 20-30 years of operation, unlike utility pipelines protected with bitumen and insulated with mineral wool which get negative references in the heat supply sphere. It is critically important to carefully observe the installation rules.
Results of the work
After the manufacturing of the pipes, we addressed our railway freight partner, "Transcontainer" PJSC, in order to fit the tight schedule. An express train was made up with practically no stops on the way, enabling the delivery to Vladivostok within 10 days. From there, the way to Partizansk took 3 hours.
During the installation, no waterproofing and insulation works had to be performed, due to that, the required performance time could be reduced, and the hydraulic test could be started far in advance of the scheduled date.
The customer was satisfied with our products and the fast delivery, that is why a new agreement was made on a new project in the new plot of land. We were glad to participate in the infrastructural improvements in the Far East, being ready for new similar projects in future.
