Product Specifications

Technical details and manufacturing context for Separator Housing

Definition

The separator housing is the main structural component of an oil separator that encloses and protects the internal separation mechanisms, provides mounting points for other components, and maintains the pressure integrity of the separation system. It serves as the primary containment vessel where oil-gas separation occurs. Constructed from materials such as carbon steel, stainless steel, or aluminum alloy, the housing is designed to withstand specified design pressures and temperatures. Typical design parameters include a design pressure range of 1.0–1.6 MPa, a design temperature range of -40 to 85 °C, and nominal diameters from 50 to 300 mm (per ISO 7005). Wall thickness ranges from 5 to 20 mm (per ASME B16.34), and surface roughness on sealing surfaces is specified as Ra 0.8–3.2 μm (per ISO 1302). Material grades may include Q235B to 304 (per GB/T 700 and ASTM A240), with housing weight ranging from 15 to 120 kg. Leakage rate is limited to ≤0.1 mL/min, and corrosion resistance is verified by a salt spray test of at least 72 hours (per ASTM B117). Hydrostatic test pressure is 1.5 times the design pressure. These values are reference ranges; actual specifications must be confirmed with the legal manufacturer or supplier for the specific model and application. The housing provides a sealed environment where oil-laden gas enters, undergoes separation processes (such as centrifugal, gravity, or coalescing separation), and allows separated oil and gas to exit through designated ports while maintaining system pressure and preventing leaks. Proper selection requires consideration of operating pressure, temperature, fluid compatibility, and installation constraints. Verification questions should address material certification, pressure testing, and compliance with applicable standards. Maintenance signals include visible corrosion, seal degradation, or increased leakage. Failure boundaries are defined by exceeding design limits or failing to meet leakage and pressure integrity requirements.

Working Principle

The housing provides a sealed environment where oil-laden gas enters, undergoes separation processes (such as centrifugal, gravity, or coalescing separation), and allows separated oil and gas to exit through designated ports while maintaining system pressure and preventing leaks. The housing's structural integrity ensures that the internal pressure is contained, and its design includes inlet and outlet connections, mounting points, and sealing surfaces. The separation mechanisms inside rely on the housing to maintain the necessary flow paths and pressure differentials. The housing also protects internal components from external contamination and mechanical damage. Its material and wall thickness are chosen to withstand the design pressure and temperature, and its surface finish on sealing surfaces ensures leak-tight joints. The housing's design must accommodate the specified nominal diameter and flow capacity, and its weight affects handling and installation. Proper functioning depends on the housing maintaining its integrity under operating conditions, and any deviation from specified parameters may indicate a need for inspection or replacement.

Frequently Asked Questions

What materials are commonly used for separator housings?

Common materials include carbon steel, stainless steel, and aluminum alloy. Material grades may range from Q235B to 304, depending on the application and corrosion requirements. Always confirm the specific material grade with the manufacturer.

What is the typical design pressure range for a separator housing?

The design pressure range is typically 1.0–1.6 MPa. However, the actual design pressure must be verified for the specific model and application, as it depends on the operating conditions.

How is the leakage rate of a separator housing tested?

Leakage rate is tested, with a maximum allowable leakage of ≤0.1 mL/min. This test ensures the housing maintains pressure integrity and prevents leaks.

What standards apply to separator housing dimensions and testing?

Relevant standards include, and leakage, ISO 7005 for nominal diameter and flanges, ASME B16.34 for wall thickness, ISO 1302 for surface roughness, and ASTM B117 for corrosion resistance. Always verify compliance with the manufacturer.
