Q:What is stainless steel pipe used for?
Stainless steel pipe is primarily used in piping systems for the transport of fluids or gases.
We manufacture steel pipe from a steel alloy containing nickel as well as chromium,
which give stainless steel its corrosion-resistant properties.
Q:Is stainless steel pipe cheaper than copper?
Copper is often more expensive than that of stainless steel.
This may sometimes change based on the current market value,
but you should expect to pay on avergage about 25% more for copper.
Maintenace of copper is a bit more time consuming if you want to maintain its finish.
Q:Can stainless steel pipe be used for potable water?
Stainless Steel Pipes
Stainless steel is corrosion resistant. They are ductile, can handle high flow rates, and are not hard to bend and cut.
More importantly, the biochemical structure of stainless steel offers the best hygiene,
making it a better choice for drinking water.
Q:What grade of stainless steel will not rust?
304 stainless steel is the most common form of stainless steel used around the world due to excellent corrosion resistance and value.
304 can withstand corrosion from most oxidizing acids.
Q:What is the strongest grade stainless steel?
440C stainless steel
Martensitic grades include 420 stainless steel,
which is used in engineering applications like shafts and 440C stainless steel – the hardest
and most abrasion resistant of all the stainless steel.
