EN 10217-1 P235TR1 welded steel tubes
EN 10217-1 P235TR1 welded steel tubesare used for high temperature service applications. It is a carbon non-alloy steel constructed for primary forming into wrought products. Its specified properties are appropriate for the normalized condition. 1.0254 is the EN numeric designation for this material. P235TR1 is the EN chemical designation.
P235TR2 Electric Welded Alloy Steel tubes have a moderately high ductility and a moderately low tensile strength among wrought carbon or non-alloy steels.
EN 10217-1 P235TR1 are reheated and furnished in full annlealed, isothermal annealed or normalised quenched and tempered condition. It has minimum yield strength of 235 Mpa.
1.0254 p235tr1 boiler tube is made of a carbon, chrome, copper, manganese, silicon, sulfur, molybdenum, nickel, niobium, phosphorus, titanium and vanadium.
1.0254 st 37.0 SAW and welded round tubes are used in the equipment of engineering, container and pipe construction as well as mechanical engineering.
EN 10217-1 P235TR2 are intended for use in systems for both pressure equipment and pipelines. It is mainly used in boiler, transportation of oil, natural gas, gas, pressure pipe, pipe for ship, structure pipe etc. The alphanumeric TR2 is for qualities with specified aluminum element, impact properties and specific inspection and testing requirements.
1.0254 st 37.0 submerged arc welded non-alloy steel tubes is a kind of material for boiler and pressure vessel steel. It has elevated content of carbon where it is heat-resistant by means of excellent bending, corrosion resistance, long-lasting organizational stability, welding performance, high strength, cold deformation ability is exceptionally good. It is characterized by a minimum yield strength of 170-230MPa.

Dimensions and tolerances | For the outside diameter D219,1 D +/-0,75 % or +/- 6 mm depending on which value is greater. The tolerances applied to wall thickness depend on the wall T For T5 +/-8 % or 2 mm (depending on which value is greater) |
Pipe lengths | Pipes with precise lengths are manufactured with the following tolerance values: for D406,4- for pipes 0- 6m -0/+25%- for pipes 6-12m -0/+50%- for pipes longer than 12m -0/to be negotiated |
Tightness | Pipes should be subject to water testing (7Mpa) or electromagnetic testing. |
Straightness | < 0,0015 of pipe length (below 3mm per every meter of pipe length) |
Tests | Mandatory tests: ladle analysis, tensile testing, transverse tensile testing of the weld > 508, tightness testing, dimension verification, visual inspection, NDT of the weld Optional tests: transverse tensile testing of the weld D= 219,1- 508, wall thickness measurement at a distance from pipe ends |
