What are the uses of spiral air ducts
Air supply, including fresh air and exhaust, has a wide range, such as
workshops, production and construction air. Due to the generation of
harmful gases, it is necessary to supply and exhaust outdoor air to the
bedroom. At this point, it is necessary to use atmospheric
transportation pipelines with high flow rate and low pressure. Spiral
air ducts are considered practical, and generally, galvanized iron pipes
or circular pipes made of iron can be used. Stainless steel pipes are
used in corrosive and humid areas; Send a cool breeze. The common type
is the pipes of central air conditioning, which require insulation
materials. The spiral air duct can be internally coated with insulation
material, which looks beautiful on the outside.
Exhaust fumes. Hotels, small rooms specially designed for tea houses,
and kitchens in hotels all generate a large amount of oil smoke that
needs to be discharged. Circular air ducts are used, which are called
oil smoke chimneys. Here, the spiral air duct should be called an oil
fume duct; remove dust. Some factories have a large amount of dust in
their delivery workshops, and special dust removal devices are provided.
For pipelines with large air flow, spiral air ducts can be used; Bulk
material transportation. During the delivery process in some factories,
loose particles need to be transported, especially spiral air ducts with
small specific gravity such as foam plastic particles, which have low
cost and good effects.
What are the advantages of spiral ducts
Good product compatibility and high standardization level; Strong
airtightness; Low ventilation consumption; Ventilation noise is low, and
circular pipes are superior to steel pipes with equal sides.
Easy factory inspection; Anti equilibrium external pressure (negative
pressure) program; Ministry of Materials; Easy installation, few
connection points, small installation space, and low installation cost.
All structures installed are aesthetically pleasing and of high grade;
Easy to raise and rinse in daily life; Small wet circumference of the
cross-section, small resistance along the way, and smaller energy loss;
Fully mechanical processing, no need for secondary processing in one
采纳高速飞式切割机，外径与内径之平均值精确度高；采用缩径套接、套管互接、法兰互接、束带互接四种方式，安装更加方便；管外保温阳雕刻 手套生产设备 果树反光膜 北京纯水设备 保定网站制作 排水槽模具质量优于矩形风管。
Adopting a high-speed flying cutting machine, the average accuracy of
outer diameter and inner diameter is high; Four methods are adopted:
reducing sleeve connection, sleeve connection, flange connection, and
strap connection, making installation more convenient; The insulation
quality outside the pipe is better than that of rectangular air ducts.
