SS 310 Tees are essential pipe fittings shaped like the letter 'T', used to split a main pipeline into a branch line, typically at a 90° angle. They are classified as either Equal Tees (where the branch diameter is the same as the run diameter) or Reducing Tees (where the branch is smaller). These critical components are fabricated from Stainless Steel Grade 310, a specialized austenitic alloy known for its exceptional high-temperature performance, specifically its resistance to oxidation and scaling up to 1035°C. Zeron Fasteners manufactures and supplies high-precision SS 310 Tees in both butt-weld and socket-weld configurations, adhering strictly to global standards. Their use is crucial in extreme service environments like petrochemical crackers, high-temperature heat exchangers, and industrial furnaces, where structural integrity and material durability under thermal stress are paramount.
