The issue of nominal pressure for metal flexible hoses

Are the flexible hoses used in storage tanks only available in a nominal pressure of 1.0 MPa? Section 3.3.1 of the standard \"Selection Criteria for Metal Hoses and Bellows Compensators for Seismic Protection of Storage Tanks\" (SYT 4073-94) specifies that \"the nominal pressure of the metal hoses should be 1.0 MPa.\" ” Are there product series with other pressure ratings for metal hoses used in other applications?

There are other pressure ratings available. Refer to GB/T 14525-1993 General technical requirements for corrugated metal hoses, and SH/T 3412 Metal hoses for petrochemical pipelines

Hello, as the original poster intended, metal hoses are used for seismic protection of storage tanks; the two standards you mentioned seem to be applicable to pipelines instead

I’m facing a similar problem now; I wonder if the original poster has solved it?
