Hastelloy: Hastelloy is a household of nickel-dependent alloys that are remarkably immune to corrosion and superior-temperature environments. It is often used in chemical processing and oil and fuel purposes.
The choice of material will count on the particular application and the necessities for temperature resistance, corrosion resistance, stress resistance, flexibility, and value. An experienced engineer or producer can advise the best content according to the applying needs.
Along with the metal and layout with the expansion joint, the nature and focus of the corrosive material have to also be regarded. For instance, some supplies might result in localized corrosion or pitting in selected metals.
Indeed, metal expansion joints can be utilized in significant-temperature apps. The utmost temperature that metal expansion joints can endure is determined by several variables such as the variety of metal used, the design with the expansion joint, and the specific application necessities.
The frequency of inspection and replacement can differ from every single few months to various many years, with regards to the functioning situations and the precise software.
Titanium: Titanium is a light-weight and powerful materials that is extremely proof against corrosion. It's exceptional flexibility and is often Employed in cryogenic and large-vibration apps.
Evidence assessments: leak exam with air, leak test with website helium and former fuel, hydrostatic tension examination for all application
Tension: The material should be in a position to resist the strain of the appliance. get more info Distinctive supplies have distinctive strain rankings, so it’s imperative that you decide on a fabric that may handle the envisioned stress array.
The look with the expansion joint may have an affect on its suitability to be used in corrosive environments. By way of example, the use of numerous plies click here or thicker bellows can increase the corrosion resistance with the expansion joint.
The chrome steel product variety is predicated within the company problems. As more info an read more example, in superior temperature applications SS321 is preferred on account of its superior high temperature corrosion Homes. SS316 is the popular grade for programs from cryogenic temperatures to 800F provider.
Picking out the best material for metal bellows and expansion joints is crucial to be sure They're long lasting and trustworthy in unique marketplace applications. Here are several factors to look at when deciding on the fabric:
Axial.By way of compression and extension, the adjacent duct flanges transfer nearer or farther from each other together the identical longitudinal axis.
Bellows Devices engineering and technical product sales team can assist you in producing suitable material choice determined by your software.
It is usually imperative that you Notice that the failure of the expansion joint can have critical effects, including damage to equipment, downtime, and protection hazards.
