In the field of offshore engineering, the safety and reliability of equipment are directly related to personnel safety and the continuity of production operations. As one of the key pieces of equipment, the quality inspection of separators is particularly important. Every separator produced by Tianmiao Company must pass the certification of China Classification Society (CCS) and the joint hydrostatic test conducted by offshore engineering experts. This rigorous quality control process ensures that the equipment can operate stably for a long time in harsh marine environments.

Separator: The “Precision Kidney” in Offshore Engineering
The Significance of CCS Certification and Joint Test of Offshore Engineering
Separators play a crucial role in offshore engineering and ship systems, with their primary function being the efficient separation of oil, gas, and water mixtures to ensure the smooth operation of subsequent processes. For this reason, the reliability and safety of the equipment must undergo the most rigorous testing. CCS certification is an authoritative system by China Classification Society for evaluating the safety, reliability, and environmental performance of ships and offshore equipment. Obtaining this certification means the equipment complies with the safety standards for international navigation and offshore operations.
Hydraulic pressure testing is a critical step to verify the structural integrity of the separator. At Tianmiao Company, this test is jointly supervised and conducted by CCS and marine engineering experts. Through simulated equipment under extreme pressure conditions, it comprehensively evaluates the pressure-bearing capacity, sealing performance, and structural stability.
The Strict Standard of Hydraulic Pressure Test
The hydraulic pressure testing process is far more complex than a simple “water injection under pressure” procedure. As per regulatory requirements, the test pressure is typically set at 1.5 times the equipment’s design pressure and must be maintained for a specified duration. Throughout this process, the inspection team will closely monitor the following key parameters:
Stability and accuracy of pressure gauge
sealing of equipment body and all welded joints,
deformation and elastic recovery of shell
reliability of auxiliary valves and interfaces
This “extreme pressure test” can effectively expose material defects, welding quality issues, and structural design deficiencies, ensuring that the equipment will not leak, deform, or develop fatigue cracks under real sea conditions.
How Tianmiao Separator Passes the Double Authentication Test
Thorough preparation before the test
In Tianmiao Company’s quality control system, the separator must undergo a complete pretreatment process prior to formal testing:
1.Equipment cleaning: Thoroughly remove internal impurities to ensure test accuracy.
2. System connection: Install calibrated pressure gauges, safety valves, and exhaust devices.
3. Documentation preparation: Submit complete design drawings, material certificates, and welding records.
Standardized testing procedures
Hydraulic pressure testing shall be conducted strictly in accordance with the following standard procedures: Stepwise pressurization: Apply pressure incrementally in a staged manner to avoid pressure shock. Pressure holding observation: Maintain the test pressure for a sufficient duration to perform comprehensive inspection. Gradual depressurization: Reduce pressure at the specified rate while monitoring equipment recovery. Final inspection: Conduct a thorough visual inspection of the internal components after pressure release.
Expert Joint Acceptance
During testing, CCS and offshore engineering experts will evaluate the system from different perspectives: CCS will focus on compliance with classification society standards and international conventions, while offshore experts will assess the equipment’s adaptability to marine-specific conditions (e.g., salt spray corrosion, wave impact, and temperature fluctuations). The separator will only receive final factory clearance upon mutual approval by both parties.
Value of Dual Authentication Test
Reliable assurance of safety performance
A separator certified by both CCS and marine engineering standards signifies: its structural design complies with the strictest marine environmental criteria, material selection and manufacturing processes meet industry-leading standards, and safety factors far exceed conventional industrial equipment requirements.
Quality Accredited International Pass
CCS-certified separators are not only recognized in the domestic market but also demonstrate competitive advantages in international offshore engineering projects. Many international oil companies and offshore contractors now consider CCS certification a mandatory requirement for equipment procurement.
economic benefit of long run operation
Equipment that has undergone rigorous hydraulic pressure testing demonstrates significantly superior service life and maintenance cycles compared to conventional products. This translates to lower operational costs, reduced production downtime, and higher return on investment (ROI).
