Portable compressed nitrogen cylinder large gas cylinder
Ring flattening test of gas cylinder:
The ring flattening test shall be carried out on one ring of width 25 mm or 4 t, whichever is the greater, taken from the cylinder body. Only the edges of the ring may be machined. The ring shall be flattened between platens until the distance between platens is in accordance with Table 4. The flattened ring shall remain visually uncracked.
1、Minimum de commande : 100 seulement
2、Utilisation des cylindres : nos cylindres en acier sans soudure sont largement utilisés dans l'industrie, les appareils médicaux, la lutte contre les incendies et la recherche scientifique.
3、ISO 9809 consists of the following parts, under the general title Gas cylinders
— Refillable seamless steel gas cylinders
— Design, construction and testing:
⎯ Part 1: Quenched and tempered steel cylinders with tensile strength less than 1 100 MPa
⎯ Part 2: Quenched and tempered steel cylinders with tensile strength greater than or equal to 1 100 MPa
⎯ Part 3: Normalized steel cylinders
4、Impact test of cylinders:
Except for the requirements set out in this subclause, the test shall be carried out in accordance with ISO 148-1.
The impact test pieces shall be taken in the direction as required in Table 5 from the wall of the cylinder. The notch shall be perpendicular to the face of the cylinder wall (see Figure 7).
