There is an error in the installation of the compressor pipelines; can a flexible metal hose be used to compensate for this?
Isn’t the pipeline on-site welded in place? How much less? If the difference is small, it can be pulled in using bolts; the stress value can be checked against the standards – as long as it remains within the specified range. Hoses can also be used, provided they meet the required pressure rating. Fix it properly
It depends on the position you want to adjust; if it’s very close to the inlet, there will be distance requirements； If it’s far from the import point, it should still work
Expansion joints can also be used in place of hoses. If the pressure is high, using a hose poses a safety risk.
Metal hoses should not be used, as their inner walls are thin and corrugated, making them susceptible to erosion; over time this can pose safety risks.
It is best not to use a hose. The welders’ union will find a way to solve it. Do not compromise on this aspect.
No compromises: lol Regarding stainless steel flexible hoses, can they provide lateral compensation? There is no relevant statement at all.
Reply 7# nbazxb: Generally, lining compensators are installed on the vertical pipes of the intermediate air ducts and the horizontal pipes at the outlets. The effect is good
If it is an inlet on one section of the compressor, metal hoses can be considered as a solution; however, it is better not to use hoses for the inlets and outlets on other sections, as metal hoses do not have ideal resistance to erosion and temperature changes. Even if there are no problems during installation, they can pose risks during future use.
In principle, metal hoses cannot be used for lateral compensation, especially over short distances. In reality, as long as the pressure is not high and the vibration is not intense, it can be used. In the case of the original poster, there is merely a discrepancy, which should be correctable. Neither metal hoses nor compensators can be used as means to adjust the pipeline installation.
Respect the original design; it should not be changed arbitrarily, and principles must be upheld.
