Modern society is developing rapidly, and clean pipe is particularly important in industries where purity and sterility are paramount, such as pharmaceuticals, food processing, and semiconductor manufacturing. Below are the key steps and considerations for clean pipe installation.
Clean Piping Valve Inspection
– Material Verification: Ensure all components come with proper documentation and meet design specifications.
– Surface Integrity: Check for any defects or contaminants on the surfaces of pipes, fittings, and seals.
– Valve Testing: Perform shell pressure and sealing tests on valves, marking and isolating any that fail to prevent misuse. The valve strength test and tightness test should be clean water, strength test pressure for the nominal pressure of 1.5 times the test time of not less than 5 minutes to shell packing no leakage as qualified, tightness test to nominal pressure, to valve sealing surface does not leakage as qualified.
Clean Pipe Processing
– Drawing Compliance: Carefully measure and cut pipes according to the design plans, considering the location and minimizing welds.
– Cutting Quality: Ensure pipe cuts are smooth and free from imperfections that could affect the integrity of the system.
– Bending Standards: Follow specified guidelines for pipe bending, checking for any defects post-bending.
Clean Pipe Installation
– Pre-Cleaning: Verify that all components are clean before installation.
– Connection Placement: Position connections to allow for easy maintenance and avoid proximity to supports.
– Alignment Checks: Measure the straightness of pipes during installation to maintain accuracy.
Pipe Rack Installation
This involves the structural support systems for the piping, ensuring stability and proper alignment of the pipes throughout the facility.
Static Dissipation
Implement measures to control static electricity, which can be a significant issue in clean environments, potentially leading to contamination or hazardous conditions.
Clean Pipe Welding Construction
Follow strict welding procedures to ensure airtight and sterile connections between pipe sections.
Purging of Clean Pipes
Before commissioning, purge the pipes to remove any particulates, moisture, or contaminants that may have accumulated during construction.
Clean Piping System Test
Conduct final testing to confirm the system meets all performance and purity criteria.
Strict compliance with clean pipeline installation specifications and operating procedures is the key to ensuring system quality and reliability. Regular maintenance and inspection are important measures to prevent contamination and failure. Through careful planning, execution, and continuous monitoring, an efficient and safe clean pipeline system can be established to meet the needs of modern industry for a high purity and sterile environment.
