Condensate Collection Vessel

Product Specifications

Technical details and manufacturing context for Condensate Collection Vessel

Definition

The Condensate Collection Vessel is a critical component within the Condensate Recovery System that receives and accumulates condensate (condensed steam) from various process points. It serves as an intermediate storage buffer, allowing for temperature stabilization, pressure equalization, and controlled transfer to subsequent treatment or reuse stages. The vessel prevents system backpressure, protects downstream equipment from thermal shock, and enables efficient condensate management in industrial steam applications. Constructed from materials such as carbon steel, stainless steel (304/316L), or pressure-rated alloy materials, the vessel is designed to operate within specified pressure and temperature ranges. Typical design parameters include a design pressure of 1.0–1.6 MPa (with special design required above 1.6 MPa), a design temperature of 150–200°C, and a volume ranging from 0.5 to 5 m³. The material of construction is often Q345R carbon steel for general service, with a corrosion allowance of 1.5–3 mm and a wall thickness of 6–20 mm, calculated based on pressure and diameter. Inlet and outlet diameters typically range from DN50 to DN200, and the vessel weight may vary from 200 to 2000 kg. Leak test pressure is specified at 1.5 times the design pressure, and insulation thickness of 50–100 mm may be applied for thermal efficiency. These values are reference ranges and must be verified for the specific model and application. The vessel is designed and manufactured in accordance with relevant standards such as GB/T 150, GB/T 713, GB/T 9119, and GB/T 4272, which serve as procurement and verification references. Always confirm model-specific values and standards with the legal manufacturer or supplier.

Working Principle

Condensate from steam traps, heat exchangers, or process equipment flows into the vessel via inlet piping. The vessel maintains a controlled pressure environment (typically slightly above atmospheric) to prevent flash steam formation and ensure smooth condensate flow. Liquid level is monitored using sensors, and condensate is discharged through outlet valves either by gravity or pump-assisted transfer to treatment systems or return lines. The vessel may include internal baffles or weirs to separate any entrained gases or particulates.

Frequently Asked Questions

What is the primary function of a condensate collection vessel?

The primary function is to collect and temporarily store condensate from steam systems, providing a buffer for temperature stabilization, pressure equalization, and controlled transfer to treatment or reuse stages.

What materials are commonly used for condensate collection vessels?

Common materials include carbon steel, stainless steel (304/316L), and pressure-rated alloy materials. The specific material grade, such as Q345R, should be confirmed based on the application and service conditions.

What design parameters should be verified before selecting a vessel?

Key parameters include design pressure, design temperature, volume, material, corrosion allowance, wall thickness, inlet/outlet diameter, weight, leak test pressure, and insulation thickness. These values must be confirmed with the manufacturer for the specific model.

What standards apply to condensate collection vessels?

Relevant standards may include GB/T 150 for pressure vessels, GB/T 713 for steel plates, GB/T 9119 for pipe flanges, and GB/T 4272 for insulation. These standards serve as references for design, manufacturing, and testing.
