These application conditions:
Can withstand temperatures of up to 165°c
Operate with pressure up to 2.5 MPa (25 bar).
Have a protective coat made from polyethylene of a high density with polyurethane thermal insulation filling the space between pipes.
The Main Pipe is an attested steel pipe according to norm PN-EN 253.
The certified seamless pipe is manufactured under accordance to EN 10216-2 and made with P235GH material.
The certified seamed pipe is manufactured under accordance to EN 10217-1, EN 10217-2 (both ≤323.9mm) or EN 10217-2 (>323.9mm) and made with P235TRI, P235TR2, P235GH (≤323.9mm) or P235GH (>323.9mm). Also, for all diameters it is under accordance of EN 10217-5 and made with P235GH material.
When using the Pre-Insulated Steel Pipes Insulated Pipelines for a hot water service, the steel pipes are galvanized according to PN-EN 10240, PN-EN ISO 1461 standards.
Thermal insulation of our Pre-Insulated Steel Pipes Insulated Pipelines:
The steel pipes we source have insulation made from rigid polyurethane between the spaces in the pipes which is made according to the requirements of the PN-EN 253 standard.
Blowing agent: cyclopentane
Thermal conductivity factor λ50:0.029W/mK
Foam density: >60 kg/m³
Compressive strength in radial direction with 10% deformation: >0.3MPa
Resistance to temperature: < 165°c
Pre-Insulated Steel Pipes Insulated Pipelines Leak Detection System:
The pre-insulated pipes we use can be equipped with a leak detection system which consists of wires being integrated with the thermal insulation. The system then monitors the entire pipeline and alerts you to any moistness that may occur before any further damage takes place. If this is of interest, PETROL STEEL will ensure your pipes are fitted with this safety precaution.
