We are leading manufacturer and stockist of Pre-Insulated Steel Pipes in China.Pipe Details:Pre-Insulated Steel Pipes are generally used for underground, building engineering where the site calls for delivery of hot water, steam and a range of other media that may be required.These application conditions of Pre-Insulated Steel Pipes:Can withstand temperatures of up to 165°cOperate 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.Specification of Pre-Insulated Steel Pipes:The Main Pipe is an attested steel pipe according to norm PN-EN 253.Seamless Pipe:The certified seamless pipe is manufactured under accordance to EN 10216-2 and made with P235GH material.Seamed/Welded Pipes: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 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: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.Further details of Pre-Insulated Steel Pipes:Blowing agent: cyclopentaneThermal conductivity factor λ50:0.029W/mKFoam density: >60 kg/m³Compressive strength in radial direction with 10% deformation: >0.3MPaResistance to temperature: < 165°cPre-Insulated Steel Pipes 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.Quality Assurance:ONE OF THE KIND, MILLIONS OF CHOICESSUPERIOR QUALITYPROMPT DELIVERYFAVORABLE FEEDBACKALL AVAILABLE IN PESCOSELECT PESCO, YOU WILL BE RIGHTFor more info and price of Pre-Insulated Steel Pipes, please send us inquiry and you will have quick reply soon.
