GNEE is an experienced stainless steel and pressure steel pipe supplier and can provide you with A269 TP316 welded stainless steel pipe in all grades and size ranges.
A269 TP316 instrument pipe has better corrosion resistance than 304 due to the higher molybdenum and nickel content, especially suitable for pitting and crevice corrosion in chloride environments.
A269 TP316L stainless steel pipe is a low carbon version of A269 TP316 stainless steel. A269 TP316L seamless pipe is popular in severe corrosive environments due to the addition of molybdenum and the material is not affected by boundary carbide precipitation.
