Pipeline Organization and Construction in Dust - free Workshop Engineering
2024.11.07
In the construction of dust - free workshops, pipeline organization and construction are of crucial importance and highly challenging tasks. Guangzhou Kunling Purification Equipment Co., Ltd., as a professional purification engineering enterprise, will talk about this key link in detail with you today.
1. Importance of Pipeline Construction
Dust - free workshops have strict requirements for environmental cleanliness, temperature and humidity, and air - flow organization. Various pipelines are like the "blood vessels" and "nerves" of the workshop. They are responsible for transporting energy and transmitting signals to ensure the normal operation of equipment in the workshop. Reasonable pipeline organization and construction are not only the basis for ensuring the smooth production process but also the key to maintaining the clean environment of the workshop. Once there are problems in pipeline construction, such as unreasonable layout leading to blocked air - flow and pipeline leakage contaminating the environment, the entire dust - free workshop may not be able to meet the expected production conditions and cleanliness standards.
2. Planning and Preparation Before Construction
(1) Interpretation of Detailed Design Drawings
Before construction, engineers must conduct in - depth interpretation of the overall design drawings of the dust - free workshop, especially the content related to pipelines. The direction, diameter size, connection mode of various pipelines, and the interface position with other equipment should be clearly identified. This is like drawing an accurate map to guide the subsequent construction. For example, for the air ducts of the purification air - conditioning system, every branch path and the position of the air supply outlet after starting from the air - handling unit should be clear; for electrical pipelines, the distribution of distribution boxes and the equipment connected by each line should be known.
(2) Material and Equipment Selection
Select appropriate pipeline materials and construction equipment according to the design requirements and the actual situation of the workshop. For pipelines transporting corrosive liquids or gases, corrosion - resistant materials such as stainless - steel pipes or specific plastic pipes should be selected. For electrical pipelines, their insulation performance and current - carrying capacity should be considered. At the same time, prepare high - quality construction tools, such as pipeline cutting equipment, welding equipment, and cable laying tools. These high - quality materials and advanced equipment are the material basis for ensuring the quality of pipeline construction.
(3) Training and Technical Disclosure of the Construction Team
Form a professional construction team and conduct targeted training for them. Due to the particularity of pipeline construction in dust - free workshops, construction personnel need to be familiar with the specifications and requirements of construction in a clean environment. For example, during the construction process, dust generation should be strictly controlled to avoid contaminating the workshop. In addition, detailed technical disclosure should be made to the construction personnel to make them clearly understand the key points and quality standards of each construction link, ensuring that each process meets the construction requirements of the dust - free workshop.
3. Key Points During Pipeline Construction
(1) Reasonable Layout and Direction
The layout of pipelines should follow the principles of "safety, rationality, aesthetics, and easy maintenance". Under the premise of meeting the process requirements, the intersection and overlap of pipelines should be minimized as much as possible. For example, for drainage pipes with slope requirements, sufficient slope should be ensured to facilitate drainage, and at the same time, there should be no conflict with other pipelines. For pipelines in the clean area, the impact on air - flow organization should be considered to avoid blocking the normal circulation of air - flow. Generally, overhead or underground laying methods are adopted, and the best scheme is selected according to the actual situation of the workshop. If it is overhead laying, it should be ensured that the height of the pipeline will not affect the operation of equipment and the passage of personnel in the workshop; if it is underground laying, anti - corrosion and waterproof treatments of the pipeline should be done well.
(2) Pipeline Connection and Sealing
The quality of pipeline connection is directly related to the stability and sealing of the entire pipeline system. For different types of pipelines, corresponding connection methods such as welding, flange connection, and threaded connection are adopted. When welding pipes, the quality of the weld should be ensured, with no defects such as pores and slag inclusions, to ensure the strength and sealing of the pipes. For pipes that need to be frequently disassembled, such as the inlet and outlet pipes of some equipment, flange connection can be used, and high - quality sealing gaskets should be used. For gas pipelines, especially those transporting clean gas, sealing is particularly important, and strict air - tightness tests should be carried out to prevent gas leakage from affecting the cleanliness and production safety of the workshop.
(3) Electrical Wiring and Grounding
Electrical wiring in dust - free workshops should meet the requirements of safety and electromagnetic compatibility. The laying of wires and cables should be neat and orderly to avoid interference between strong - current and weak - current lines. At the same time, the lines should be well - marked for the convenience of future maintenance and inspection. The grounding system is an important measure to ensure the safe operation of electrical equipment and the safety of personnel. In the dust - free workshop, a complete grounding network should be established to ensure that all electrical equipment can be reliably grounded, prevent static electricity accumulation from damaging sensitive equipment such as electronic products, and avoid safety accidents caused by electrical failures.
(4) Coordination with Other Construction Links
The construction of a dust - free workshop is a complex system engineering, and pipeline construction needs to be closely coordinated with other construction links. For example, when installing walls and ceilings, holes for pipelines and installation positions of cable trays should be reserved; communicate and coordinate with the equipment installation team to ensure that the interfaces of equipment are accurately connected with pipelines. This cross - link coordination work is like a carefully choreographed dance, and each link must cooperate with each other to make the entire project progress smoothly.
4. Inspection and Acceptance After Construction
(1) Pipeline Pressure Testing and Purging
After the construction is completed, pressure tests are carried out on various pipelines to test the strength and sealing of the pipelines. For liquid pipelines, a hydrostatic test is carried out according to the design pressure; for gas pipelines, a pneumatic test is carried out. After the test is qualified, the pipelines are also purged to remove debris and dust inside the pipelines. Especially for clean - gas pipelines and process pipelines, the purging work should be particularly meticulous. Clean air or nitrogen can be used for multiple purgings until the discharged gas meets the cleanliness requirements.
(2) Electrical System Testing
Conduct insulation resistance testing, grounding resistance testing, etc. on the electrical system to ensure that the insulation performance of electrical lines is good and the grounding system is reliable. At the same time, conduct functional tests on electrical equipment such as distribution boxes, switches, and sockets to check whether they can work normally. For some electrical equipment with special requirements, such as automatic control systems, system - level commissioning should also be carried out to ensure that their control functions are accurate.
(3) Overall Acceptance
After each individual test is qualified, an overall acceptance is organized. The construction party, the design party, and relevant regulatory departments are invited to participate in a comprehensive inspection of the pipeline engineering of the dust - free workshop according to national and industry standards. The acceptance content includes pipeline layout, connection quality, identification, test reports, etc. Only through strict acceptance can the pipeline engineering of the dust - free workshop be truly completed, providing a solid guarantee for the subsequent production and operation of the workshop.
