What is the difference between 304, 316, and 316L tee fittings?
316/316L contains molybdenum for enhanced corrosion resistance, especially in chloride-rich environments; 316L is low-carbon for better weld corrosion resistance.
What sizes are commonly available for stainless steel equal tees?
Standard 1/2" – 24" (DN15 – DN600), with schedules from Sch 5s to Sch XXS; custom sizes available on request.
Are the fittings suitable for high-pressure systems?
Yes, butt-weld fittings are designed to withstand high pressure and temperature, with precise wall thickness and strong weld ends.
