Stainless steel wphy 42 fittings are used in the manufacture of several equipment found in institutional pools. Whether for the manufacture of lifeguard chairs, springboard bases, supports for cables, ladders or starting posts, stainless steel is ideal, because it is solid, durable and aesthetic.
As this equipment represents significant investments, many customers are rightly concerned about ANSI B16.5 Flange maintenance and durability.
What is stainless steel?
When presenting stainless steel a694 f65 fittings, it must first be considered as a steel derived from a typical composition of iron, manganese and carbon.
Stainless steel can be divided into five main families and more than thirty categories. The stainless steel used in swimming pools is of the "AUSTENITIC" family of the 300 series and, particularly the category 304. In addition to being used by the swimming pool industry in an almost exclusive way, alloy steel flanges are found in many other products such as kitchen sink, household appliance, architectural ramp, etc. Because of the multiple qualities of stainless steel weld neck flange, its production is equivalent to more than 50% of all stainless steels worldwide.
Occasionally manufacturers are asked for information on alloy steel fittings. This category is very similar to 304, to which 2% molybdenum has been added. This steel provides greater protection against corrosion in very specific situations. For example, boats that sail on the oceans, because of the salinity of the water, will use 316 steel for certain mechanical parts including those in full immersion while the equipment on deck, are made in en 1092-1 because they can be cleaned more easily. When it comes to the pool industry, the biggest manufacturers have always had success using 304 stainless steel.
Why does stainless steel resist corrosion well?
Ordinary steels asme b16.9 fittingswill rust unless they are completely protected from the atmosphere. We are all too familiar with this brown and friable film of iron oxide which gnaws at the metal on the surface and which, over time, makes it lose all utility.
The stainless steel fasteners also rust, but instead of a destructive and unsightly iron oxide film, it is a chromium oxide film that forms on the surface, invisible, tough and highly protective. It is formed when oxygen becomes one with chromium.
Prevention and maintenance
When you receive new equipment, it is important to establish a maintenance schedule to prevent the asme b16.11 threaded fittingsfrom becoming invalid. Messy surfaces are often your greatest enemy. All dirt, grease, and debris from evaporation should be removed by cleaning the surface with fresh water (do not use pool water) and wiping with a dry cloth. Cleaning every 2 to 4 weeks should usually be enough.
The equipment installed in new swimming pool constructions at stainless steel stub end, very often airtight and having a high humidity, seems to require special attention. Make sure to clean the places that are more difficult to access such as the undersides of the platforms.
If your equipment already shows significant deposits of dirt, you must therefore remove them so that the oxygen in the air can come into contact with the chromium contained in Stainless steel blind flangeto form the protective chromium oxide film. Cleaning with clear water with a nylon pad is normally sufficient.
