| For welded tubes the tolerance on wall thickness is: ± 10 % . |
| for M and H series and Type L: – 8 % with the plus tolerance limited by the mass tolerance, for Types L1 and L2. |
| The mass tolerance on welded tubes is: |
| ± 7,5 % on bundles of 10 tons or more, for M and H series and Type L ; |
| +10% -8% on individual tubes for Types L1 and L2. |
| For seamless tubes the tolerance on wall thickness is ± 12,5 %. |
| The maximum tolerance does not apply if the actual weight of a bundle does not exceed the theoretical weight, calculated from the nominal mass per unit length (see Tables 2, B1, B2, or B3, as appropriate), by more than + 7,5 %. |
EN10255 Test Project and Application
EN10255 Test Project
Leak tightness test: We fill the steel pipe with gas or liquid and conduct leak testing immediately to ensure product safety for the ongoing project.
Flattening test:After flattening the welded tube, the weld is alternately placed in the direction of 0° or 90° (12 or 3 o ‘clock), and until the distance between the plates measured under load reaches 75% of the original outer diameter of the tube, and the distance between the two plates measured under load reaches 60% of the original outer diameter, no visible cracks or defects can be directly observed except for the weld.
Bend test:Applicable to bare tubes with a specified outer diameter (D) of 17.2 mm, bent in a 90° direction according to EN ISO 8491.
Tensile test:Carried out on bare pipe of steel pipe according to EN10002-1.
Application of EN10255
Agriculture, animal husbandry and fishery: Food storage and transportation, meat and aquatic products frozen processing equipment.
Commerce: Materials storage and transportation, packaging tools.
Construction industry: The production of anti-corrosion industrial and civil building roof panels and roof grids.
Automotive industry: Production of anti-corrosion parts for automobiles.
