The joint of stainless steel air duct is axial, and the compressive strength of the joint is much higher than that of the axial straight joint, so it can ensure that there is no crack at the joint under 1.5 times of the pressure. Because its raw material, galvanized coil, is lower than a whole galvanized sheet, and the price is lower, coupled with its standardized production and manufacturing and standardization, the project cost is lower than that of rectangular frame air duct; For others, the total cost is relatively low due to less support and equipment labor. Because the four corners of rectangular frame air duct are easy to cause seepage, the reasonable total current carrying area is reduced, the gas circulation is good, and the reasonable total current carrying area is large, so the secondary noise of the product is low, because its compressive strength is large.

不銹鋼風(fēng)管的所有領(lǐng)域要發(fā)展，他依附于并不是他的價錢，理應(yīng)是這一領(lǐng)域的能力素質(zhì)。在那么猛烈的市場需求中，中開辟終堅持不懈自身的規(guī)則，竭盡全力保證是，憑著高質(zhì)量高服務(wù)項目的規(guī)則，到迄今為止，我們是獲勝的。中創(chuàng)完成了零投訴、零感恩回饋。

All fields of stainless steel air duct need to be developed. It is not his price that he depends on, but his ability and quality in this field. In such a fierce market demand, Zhongkai has always adhered to its own rules and made every effort to ensure that, by virtue of the rules of high-quality and high service projects, we have won so far. Zhongchuang has completed zero complaints and zero gratitude feedback.

現(xiàn)階段有很大部分的企業(yè)因發(fā)展比較晚，且資產(chǎn)整體實力比較有限，可她們?yōu)榱烁玫啬茉阡N售市場中攻占一席之地，大打競爭。不銹鋼風(fēng)管別是一些小企業(yè)、手工坊式的企業(yè)，那樣的企業(yè)生存能力不容易長久。由于確信一個企業(yè)要發(fā)展，是兩者之間的企業(yè)文化藝術(shù)跟營銷策略的發(fā)展離不了的。實際上現(xiàn)階段核心的或是白鐵皮這一類的風(fēng)管，但由于這種風(fēng)管環(huán)境保護(hù)、使用壽命、防水、隔音降噪、載重等各層面原因，在工程施工跟維護(hù)保養(yǎng)上存有許多的缺陷。這就造成了銷售市場須要一種新的商品來改進(jìn)這一艱難，新式不銹鋼風(fēng)管的展現(xiàn)，恰好融入了銷售市場的須要，在根據(jù)很多工程項目利用及實際證明后，逐漸的被投資人房地產(chǎn)商所接受。

At this stage, there are a large number of enterprises that have developed relatively late and their overall asset strength is relatively limited, but they are fighting against price competition in order to better occupy a place in the sales market. Stainless steel air ducts are small enterprises and manual workshops. It is not easy for such enterprises to survive for a long time. Because we are convinced that the development of an enterprise is inseparable from the development of corporate culture and art and marketing strategies between the two. In fact, at this stage, the core or galvanized iron sheet air duct has many defects in engineering construction and maintenance due to the environmental protection, service life, waterproof, sound insulation and noise reduction, load and other aspects of the air duct. This has caused the difficulty that the sales market needs a new product to improve. The display of the new stainless steel air duct just fits in with the needs of the sales market and is gradually accepted by the investors' real estate agents after being used and proved by many projects.

伴隨著暖通行業(yè)一直發(fā)展，商品合理布局已經(jīng)悄悄的造成變動。低碳早已變成暖通工程商品的基本上需求。暖通工程企業(yè)一直運用發(fā)展的高新科技，發(fā)展商品的能耗等級，開發(fā)設(shè)計電力能源替換跟再生資源利用，研發(fā)新冷媒等。不銹鋼風(fēng)管銷售市場上按材料某些分成三類：熱鍍鋅不銹鋼風(fēng)管、不銹鋼板不銹鋼風(fēng)管及其復(fù)合型不銹鋼風(fēng)管。

With the continuous development of the HVAC industry, the reasonable distribution of commodities has quietly caused changes. Low carbon, environmental protection and energy conservation have already become the basic demand for HVAC products. Heating and ventilation engineering enterprises have been using the developed high-tech to develop the energy consumption grade of goods, develop and design the replacement of electric energy and the utilization of renewable resources, and develop new refrigerants. On the sales market, stainless steel air ducts are divided into three categories according to some materials: hot-dip galvanized stainless steel air ducts, stainless steel sheet stainless steel air ducts and composite stainless steel air ducts.

為了更好地使機器設(shè)備做到綠色的總體目標(biāo)，各企業(yè)均縈繞綠色的主題風(fēng)格發(fā)展相關(guān)主題活動， 在新產(chǎn)品研發(fā)、設(shè)計產(chǎn)品、生產(chǎn)制造加工工藝、生產(chǎn)流水線方法改革創(chuàng)新等層面增加資金投入幅度，提高機器設(shè)備的進(jìn)升。另外，在生產(chǎn)制造層面也高度重視，各企業(yè)均制定的評定系，在生產(chǎn)能力提升的前提條件下竭盡全力角逐著陸耗能，生產(chǎn)制造邊上階段也盡量避免染上物的排出。

In order to better achieve the overall goal of green environmental protection for machinery and equipment, all enterprises have developed relevant theme activities around the theme of green environmental protection, increased capital investment in new product research and development, product design, manufacturing and processing technology, production line method reform and innovation, and improved the progress of machinery and equipment. In addition, environmental protection and energy conservation are also highly valued at the production and manufacturing level. The evaluation system formulated by all enterprises strives to compete for landing energy consumption under the premise of improving production capacity, and the discharge of contaminants is also avoided as far as possible at the stage of production and manufacturing.
