Product Overview

A stainless steel tee is a T-shaped or Y-shaped pipe fitting primarily used for diverting, merging, or changing the flow direction of fluids in industrial piping systems. As a critical component ensuring process continuity and system safety, it typically adopts butt-welding connection to guarantee strong and leak-proof pipeline joints.

Product Advantages

Superior Corrosion Resistance

Made of high-performance stainless steel grades such as 316L and S32760, with a dense oxide film formed after acid pickling and passivation, effectively resisting chloride ion stress corrosion in seawater and harsh environments.

Excellent Pressure-Bearing Capacity

Covers wall thickness classes from SCH10S to SCHXS, combined with seamless welding technology, ensuring long-term stable operation under high-temperature and high-pressure systems while avoiding leakage risks.

Diverse Structural Designs

Offers equal, reducing, 45°, and Y-type tees to meet various pipe diameter matching and flow direction requirements, with smooth flow channels that minimize pressure loss.

Wide Process Applicability

Materials are non-toxic and non-precipitating, meeting strict cleanliness standards for biopharmaceuticals, food and beverage, and purified water systems.

Main Applications

Petrochemical & Natural Gas

Stainless steel tees are used in refining units and transmission pipelines for medium diversion and flow control, resistant to high temperature, high pressure, and process medium corrosion.

Marine Engineering & Shipbuilding

Applied in seawater pipelines and ballast water systems, offering excellent resistance to chloride corrosion for long-term structural stability.

Municipal & Construction Engineering

Suitable for urban water supply, heating, and fire protection systems, ensuring reliable connections, long service life, and low maintenance costs.

Power & Mechanical Equipment

Serves as a key connection component in boilers, heat exchangers, and compressors, adapting to various media such as steam and cooling water.

FAQ

Q: What is the specific connection type for these tees?

A: All products are butt-welding (BW) type, ensuring seamless integration and stronger pressure resistance in the pipeline system.

Q: Can you provide non-standard wall thickness for GOST 21.3mm?

A: We strictly follow GOST 17376 standards. Orders start from 21.3mm, and specific wall thickness classes (e.g., SCH40S) can be selected according to your requirements.

Q: What makes 316L material particularly corrosion-resistant?

A: 316L contains molybdenum and has low carbon content, offering excellent resistance to intergranular corrosion, especially suitable for seawater and chemical environments with high chloride levels.

Q: Can you provide material certificates for classification society approval?

A: Yes, common materials such as 12Х18Н10Т and 316L can be supplied with complete mill test certificates and physical property reports, meeting marine application requirements.
