Stainless steel caps are usually used for protecting the end of pipe and other fittings, so the shape is disigned according to the shape of pipe line. Material stainless steel grades Also known as "marine grade" stainless steel due to its increased ability to resist saltwater corrosion compared to type 304. SS316 is often used for building nuclear reprocessing plants. End caps are widely well-known for the utmost output and outstanding results that it gives.
