Spirax Sarco UTD30 Thermodynamic Steam Traps with Swivel Connector - IBR Certified
Spirax Sarco UTD30 thermodynamic steam traps with swivel connector. IBR certified, stainless steel, for mains drainage & tracing. Buy from PC Engineering
Overview
The Spirax Sarco UTD30 series are stainless steel thermodynamic steam traps designed for efficient condensate removal in industrial steam systems. Featuring an electroless nickel preparation (ENP) finish, these traps offer excellent corrosion resistance and energy efficiency across demanding plant environments.
The UTD30 incorporates an integral strainer and attaches to pipeline connectors via a two-bolt swivel arrangement, enabling quick replacement without disturbing the main piping. This modular design significantly reduces maintenance downtime — a critical consideration for continuous process plants.
Four variants are available: UTD30L and UTD30H for standard applications (low and high capacity respectively), plus UTD30LA and UTD30HA versions equipped with anti-air-binding discs for systems where air venting is a concern. All models comply with Indian Boiler Regulations (IBR) 1950, making them suitable for statutory installations across Indian manufacturing facilities.
Key Features
- Stainless steel construction with ENP finish for corrosion resistance
- Integral strainer prevents debris from affecting trap operation
- Two-bolt swivel connector allows fast trap replacement without pipe modification
- Anti-air-binding disc option (LA/HA variants) for improved air handling
- IBR certified — compliant with Indian Boiler Regulations, 1950
- Modular pipeline connector system — compatible with PC10HP, PC3, and PC4 connectors
- Optional insulating cover for outdoor or cold-climate installations
- High operating pressure capability up to 30 bar g saturated steam

Applications
The UTD30 series thermodynamic steam traps are suitable for:
- Steam main drainage — removing condensate from distribution headers - Steam tracing lines — protecting heat tracing systems in refineries, chemical plants, and tank farms - Process equipment drainage — heat exchangers, jacketed vessels, and dryers operating at moderate condensate loads - Power plants and utilities — boiler house and turbine auxiliary steam systems - Pharmaceutical and food processing — where IBR compliance and stainless steel construction are mandatory
Industries served include petrochemicals, refineries, fertilizers, textiles, sugar mills, paper manufacturing, and any IBR-regulated steam installation.
