A flexible corrugated stainless steel hose, externally reinforced with stainless steel wire braid, fitted with steam union couplings on both ends.
Steam unions are designed for safe, leak-free connection and disconnection of steam lines without twisting the hose, making them ideal for high-temperature, high-pressure steam transfer.

Construction

1. Inner Hose

   • Corrugated stainless steel (SS304 or SS316) for flexibility and resistance to heat, pressure, and corrosion.

2. Braid Reinforcement

   • Single or double-layer stainless steel wire braid to enhance working pressure capacity and mechanical durability.

3. End Fittings – Steam Unions

   • Both ends fitted with male/female steam union couplings (usually in BSPT or BSPP thread) for quick connection.

   • Designed with sealing faces and locking collars for secure, pressure-tight joints.

Typical Specifications

• Size Range: 1/2" to 4" (DN15 – DN100)

• Working Pressure: Commonly up to 18–20 bar for saturated steam (higher ratings possible on request).

• Temperature Range: –40 °C to +230 °C for saturated steam, up to +600 °C for certain superheated applications.

• Material Options:

  • Hose & braid: SS304 / SS316

  • Steam unions: Carbon steel, brass, or stainless steel (depending on application)

• Standards: Can be manufactured to ISO 10380 or BS 6501 for metal hoses; steam unions to BS 336 or equivalent.
