Ventilation pipes are suitable for transportation in all walks of life. Factory buildings and air conditioners are used. This skill is also used in shipbuilding industry. It is relatively early for this skill to move to the shipbuilding industry. The following ventilation duct processing tells you its application in shipbuilding industry.

通風(fēng)管道加工

薄鋼板法蘭通風(fēng)管道內(nèi)、外表層和內(nèi)部絕熱材料粘接牢固，是確保復(fù)合材料的基本條件之一。超出面積的板材缺陷，不只影響風(fēng)管運用壽命，并且有時會下降其保溫效果。所以缺陷不得大于6‰，以到達材料在體系中的正常運用。潔凈空調(diào)體系的風(fēng)管采用鍍鋅鋼板加工。

It is one of the basic conditions to ensure the composite material that the inner and outer layers of the thin steel flange ventilation duct are firmly bonded with the internal insulation materials. The board defects beyond the area not only affect the service life of the air duct, but also reduce the insulation effect sometimes. Therefore, the defect should not be greater than 6 ‰, so as to reach the normal use of materials in the system. The air duct of clean air conditioning system is made of galvanized steel plate.

吊架，加固框，連接件均采用鍍鋅件;法蘭墊料應(yīng)用有彈性、不產(chǎn)塵，有強度的軟橡膠或者乳膠海綿;風(fēng)管的外保溫采用難燃橡塑板，以專用膠張貼，禁止在施工過程中運用玻璃棉等纖維制品。多個排煙分區(qū)合用排煙排風(fēng)體系，這種狀況的話，就是電動閥+排煙風(fēng)口，平時常開排風(fēng)，著火封閉非著火點排煙分區(qū)的設(shè)置在支管上的電動閥。

The hanger, reinforcement frame and connecting parts are galvanized parts; the flange cushion material shall be flexible, dust-free, and strong soft rubber or latex sponge; the external insulation of air duct shall be made of flame-retardant rubber plastic plate and pasted with special glue, and fiber products such as glass wool are prohibited in the construction process. Multiple smoke exhaust zones share the smoke exhaust system. In this case, it is the electric valve + smoke exhaust outlet, which is normally open for exhaust and closed on fire. The electric valve is set on the branch pipe of smoke exhaust partition without ignition point.

對于民用建筑，通風(fēng)管道在設(shè)計階段，各工種(暖通、給水排水，供電照明)應(yīng)洽談好空間分隔，定出每種管道的標(biāo)高規(guī)模。一般狀況下不得越出給自己規(guī)定的界限。遇有單個管段要越界時應(yīng)與其他工程洽談。在通風(fēng)體系中的風(fēng)管是相互連接的一個整體，必然得遵從各支路阻力平衡規(guī)則，當(dāng)風(fēng)管體系的結(jié)構(gòu)方式、管道尺度一經(jīng)確認(rèn)，在風(fēng)機作用下，各段的風(fēng)量是按阻力平衡規(guī)則自動分配的。

For civil buildings, in the design stage of ventilation pipes, all types of work (HVAC, water supply and drainage, power supply and lighting) should first discuss the space separation and determine the elevation scale of each kind of pipeline. In general, they should not go beyond the limits set by themselves. When a single pipe section needs to cross the boundary, it shall be discussed with other projects. In the ventilation system, the air duct is a whole connected with each other, and it must obey the resistance balance rules of each branch. Once the structural mode and pipe scale of the air duct system are confirmed, the air volume of each section is automatically distributed according to the resistance balance rule under the action of the fan.
