In this article we write some suggestions that can help to keep stainless steel manways and stainless steel manholes functional over time, and that can also contribute to the reduction of extraordinary maintenance and related costs for companies.
CORRECT INSTALLATION OF THE COMPONENTS
First of all, it is necessary that the stainless steel manways and the stainless steel manholes are installed correctly and that all components of the production system are well aligned with each other. The testing phase is essential to verify that the system, once activated, works correctly, according to the technical specifications for which it was built, and in complete safety, respecting the regulations of the sector.
MAINTENANCE TIPS
Here are some tips that can be helpful to anyone who is looking for information regarding the maintenance (or purchase) of accessories for tanks, cisterns and stainless steel plants:
• Choice of material: if stainless steel manways or stainless steel manholes are exposed to the external environment or corrosive substances, when purchasing you should consider choosing manways and manholes made of AISI 316 stainless steel.
• Surface finish: in the long run, higher finishes require less maintenance. This could help to reduce the number of production cycle interruptions and the resulting reduction in operating costs, as the need for frequent replacements or urgent repairs can be significantly reduced. The choice of investing in high quality materials and advanced finishing techniques is therefore economically advantageous as well as hygienically preferable.
• Manufacturer’s instructions: Always refer to the manufacturer’s instructions for any specific maintenance instructions is a good practice both for safety during maintenance operations and to prolong the integrity of system components. It is very important to always follow the manufacturer’s recommendations in order to optimize the performance and durability of stainless steel accessories. Regular maintenance will extend the service life of stainless steel manways and stainless steel manholes, as well as all plant components.
• Regular inspections: it is a good rule to periodically check the condition of the gaskets and fixing screws (stainless steel tie rods and handrails). Every component of the stainless steel accessory for tanks and cisterns must be intact and functional. Any debris or processing deposits must be removed.
• Replacement of gaskets: if signs of deterioration are noted during the scheduled inspection, the gaskets must be replaced promptly. The gaskets are available as spare parts in different materials such as EPDM, NBR, Silicone, Viton, PTFE. Many factors influence the field of corrosion and it is therefore up to the user to evaluate which material is best suited for gaskets, based on application and production cycle characteristics.
• Verification of correct operation: during routine maintenance operations, the correct functioning of the mechanisms for opening/closing the stainless steel manways and stainless steel manholes must also be checked, including screws and fixing bolts (stainless steel tie rods and handrails). They must be firmly anchored and functional. Any loosening could compromise the tightness of the manways and stainless steel manholes, as well as present a safety risk situation.
• Cleaning: cleaning the stainless steel surfaces with water and solutions appropriate to the type of construction material of the stainless steel manways and stainless steel manholes. We recommend avoiding the use of aggressive or abrasive detergents that could damage the surface of stainless steel or gaskets and seals in general. Remember that AISI 316 steel is more resistant to corrosion than AISI 304 stainless steel. If necessary, dry surfaces thoroughly to prevent water stagnation or stains.
Maintenance and spare parts: environmental and sustainability considerations
In an era where sustainability is at the heart of corporate policies and nations, choosing durable materials and manufacturing processes that extend the life of components and reduce their replacement frequency helps companies not only to lower business costs but also to decrease environmental impact.
Through a thorough understanding of the operation of stainless steel fittings to be installed in their own production processes, on stainless steel tanks and cisterns, as well as their manufacturing steps and their technical specifications, user companies and plant technicians can make informed purchasing and maintenance choices, opting for good workmanship and helping to position themselves as leaders in their sector for quality and innovation.
