A detailed introduction: an electronics factory in Suzhou installed our stainless steel welded ventilation pipe of Qiaohui HVAC.

Suzhou Qiaohui HVAC Equipment Co., Ltd. is mainly engaged in the processing and engineering construction of environmental protection ventilation pipes and stainless steel welded pipes, covering Jiangsu, Zhejiang, Anhui and other places. It installed stainless steel welded ventilation pipes for an electronics factory in Suzhou, and the relevant information is as follows:

Construction technology:

Construction principle: according to site conditions, cooperate with civil engineering to reserve and embed. Follow the principle of underground first, then on the ground, prefabricated first, then installed, first in charge of branch pipes, first in vertical pipes and then in horizontal pipes. The same pipeline shall be constructed in the order of high first, then low, first in system test, then washed and suppressed, and finally in system acceptance.

Process flow: fabrication and installation of pipeline supports and hangers → prefabrication and storage of pipelines → transportation and arrangement of pipelines → assembly and welding of pipelines → hoisting of pipelines → welding of fixed ports of pipelines → pressure test and flushing of pipelines → oiling of welding joints, painting of color rings → data sorting and completion.

Pipeline materials and welding methods: The stainless steel pipeline systems involved in this electronic factory project include PV, CDA, GN2, etc. The pipeline materials are 304AP, 304BA and 316LEP stainless steel pipes respectively. Among them, EP pipeline is welded by automatic welding machine, BA pipeline is welded by automatic welding as far as possible, and AP pipeline is welded by manual argon arc welding.

Key points of pipeline storage and transportation: Stainless steel pipes should be stored in a dry environment, put on shelves and stored in layers, and the outer protective film and the protective end caps at both ends of the pipes should not be damaged, and they should be stored separately from carbon steel pipes. It is forbidden to open the end cover before installation, and clean it with anhydrous alcohol if there is any pollution inside. After the large package of the pipeline is disassembled, the single branch pipe needs to be wrapped with plastic protective film for protection, and it is forbidden to pry it with a steel crowbar during handling to avoid scratching the surface.

Matters needing attention in construction:

The blue prints.the design: it is necessary to check the design errors, such as whether the pipeline and pipe diameter are reasonable, the division of valves and instruments, the requirements of pipeline insulation, and the correct matching of valves and flanges.

Verification of construction scope: Pay attention to whether there are any omitted items in the bidding. If the GN2 sub-cylinder and the exhaust condensation and drainage part are omitted in the bidding of this project, it is necessary to consider changes in advance.

Material submission and optimization: through communication with the owner, some materials can be optimized, such as changing the pipeline material of cleaning vacuum system from SCH80 pipeline to UPVC water supply level, adjusting the reserved valve form of bulk gas system and the wall thickness of stainless steel pipe, etc., so as to reduce the cost under the premise of meeting the system requirements.

Space management: As there are many process piping systems, it is necessary to effectively manage the space of the construction drawings, coordinate with various disciplines to adjust the pipeline spacing and elevation of the common pipeline supports in the core area, and determine the pipeline direction on site for the corridor, outer pipe bridge and power station with inaccurate drawings, draw a single-line diagram and count the welding workload.

Advantages of Qiaohui HVAC: Qiaohui HVAC has excellent production equipment, accurate blanking and low material consumption, and can quickly produce a variety of high-quality products. Its production and installation team has a high level and strong after-sales service, which can track the service from production to use, help solve all kinds of abnormalities encountered in installation and use, and ensure the smooth installation and stable operation of stainless steel welded ventilation pipes in electronic factories.
