Description
High-Performance Stainless Steel Tee Fittings – Precise Flow Distribution & Corrosion Resistance
Specifications & Connection Types of Stainless Steel Tee Fittings
- Size Range: 1/2″ – 24″ (DN15 – DN600), custom large-size options available.
- Wall Thickness Schedule: Sch10S, Sch40S, Sch80S (compliant with ASTM A403).
- Connection Types:
- Butt Weld: Designed for high-pressure and high-temperature pipelines, with welding strength close to base metal.
- Socket Weld: Widely used for small-bore sizes (≤2″) with simple and fast installation.
- Threaded: Easy to disassemble and maintain, the preferred option for low-pressure working conditions.
Key Features
- Material Grades: 304/304L, 316/316L. 316L contains Molybdenum (Mo), improving resistance to chloride pitting corrosion by over 30% (tested in accordance with ASTM G48).
- Forming Process: Adopts hydraulic cold bulging forming combined with solution treatment to eliminate intergranular corrosion risk and ensure uniform metallographic structure.
- Surface Treatment: Pickling and passivation (Ra ≤ 2.5μm) or mechanical polishing (Ra ≤ 0.4μm), meeting sanitary requirements for pharmaceutical and food industries.

Application Scenarios of Stainless Steel Tee Fittings
- Petrochemical & Refining: SS tee fitting for high-temperature oil and gas distribution in catalytic cracking units, capable of resisting H₂S corrosion.
- Shipbuilding Industry: Steel t connector applied in seawater cooling systems, matched with titanium alloy nuts to avoid galvanic corrosion.
- Food & Pharmaceutical Industry: Steel t pipe for CIP cleaning pipelines with dead-space-free inner wall; electrolytic polishing ensures surface roughness ≤0.4μm.
- Hydrogen Energy Storage & Transportation: 316L stainless t fitting has passed low-temperature impact tests (-196℃, KV8≥60J), suitable for liquid hydrogen piping systems.
Purchasers’ Common FAQs
A: Seamless tees are formed from a single billet (ASTM A403 WP316L), offering uniform grain structure and no fusion line – ideal for pressures >10 MPa. Welded tees (fabricated from pipe) are cost-effective for large diameters (>12″) but require 100% X-ray inspection. For high-pressure gas (>15 MPa), always choose seamless. We provide mill certificates (EN 10204 3.2) for each batch.
A: Yes. Our 316L stainless steel tee fittings can be heat-treated and hardness-controlled (≤22 HRC) to meet NACE MR0175/ISO 15156 for H₂S environments. Additional testing includes HIC (Hydrogen Induced Cracking) and SSC (Sulfide Stress Cracking) per NACE TM0284. Request our NACE-certified material report.
