管道——我們在生活中隨處可見，雨水管、下水道管、排水管等等，但是這都不是我們要介紹的管子，小編要說的管子是螺旋風管的一種。螺旋式風管又分為許多種，其中白鐵風管就是其中之一，這種白鐵風管就算是在潮濕的環(huán)境中也不會腐蝕、生銹，是不少人喜愛的一種風管。
Pipes - We can see them everywhere in our lives, such as rainwater pipes, sewer pipes, drainage pipes, etc., but these are not the pipes we are going to introduce. The pipes we are going to talk about are a type of spiral air duct. There are many types of spiral air ducts, including white iron air ducts. This type of white iron air duct will not corrode or rust even in humid environments, making it a favorite type of air duct for many people.
螺旋式風管的安裝大大減少了管道與管道的接合點，降低了管道接頭處泄漏的程度，典型的螺旋式風管長度為3~6米，而矩形風管長度僅為1~1.5米；兩個螺旋式風管的連接只需一根管道接頭，而傳統(tǒng)的矩形風管連接通常需要一個完全獨立的雙法蘭系統(tǒng)。
The installation of spiral air ducts greatly reduces the joint between pipes and the degree of leakage at pipe joints. Typical spiral air ducts have a length of 3-6 meters, while rectangular air ducts have a length of only 1-1.5 meters; The connection of two spiral air ducts requires only one pipe joint, while traditional rectangular air duct connections typically require a completely independent double flange system.
一、產(chǎn)品標準化
1、 Product standardization
白鐵螺旋管附件(管件和接頭)的生產(chǎn)已經(jīng)高度自動化、系統(tǒng)化，并實現(xiàn)了工業(yè)化生產(chǎn)。
The production of white iron spiral pipe accessories (pipe fittings and joints) has been highly automated, systematized, and industrialized.
二、低安裝費
2、 Low installation cost
環(huán)形管路系統(tǒng)的安裝時間僅為矩形管路的1/3。
The installation time of the annular pipeline system is only 1/3 of that of the rectangular pipeline.
三、通常只需要較小的安裝空間
3、 Usually requires only small installation space
同樣的安裝空間，直徑為200 mm的圓形管子可以代替250×150 mm的矩形管子，而不會產(chǎn)生任何壓降。幾個平行的圓管代替扁平的矩形管，而無需額外的安裝空間。綜合考慮各種因素，在大多數(shù)情況下，圓形管子比長方形管子占用更少的空間。對于同樣的壓力特性，幾個圓形管道的安裝空間通常與一個矩形管道的安裝空間一樣或更少。很多長方形管系需要用4個螺栓系統(tǒng)來安裝，因此管系每個方向都要增加40~80 mm。
With the same installation space, a circular pipe with a diameter of 200 mm can replace 250 × 150 mm rectangular tube without any pressure drop. Several parallel circular tubes replace flat rectangular tubes without requiring additional installation space. Considering various factors, in most cases, circular tubes occupy less space than rectangular tubes. For the same pressure characteristics, the installation space for several circular pipes is usually the same or less than the installation space for a rectangular pipe. Many rectangular pipe systems require a 4-bolt system for installation, so pipe systems need to be increased by 40 to 80 mm in each direction.
