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 is 304 stainless steel pipe?
Alloy 304 is an austenitic alloy, which is made up major constituents of nickel and chromium.
The Stainless Steel 304 Pipe/ Tube is designed with high corrosion and oxidation resistance properties.
These alloys have excellent formation as well as welding properties.
Q:Are stainless steel pipes good?
Stainless Steel Pipes are popular for their resistance to corrosion. Limited maintenance,
familiar shine and its resistance make it an ideal choice for many installations;
which needs both strengths for steel as well as resistance to rust and corrosion.
