Air supply and ventilation: In environments like factory workshops where harmful gases are produced and must be exhausted, external fresh air needs to be supplied indoors. This requires air transfer ducts with large flow and low pressure, for which spiral ducts are most suitable.

Mine gas extraction ducts typically use steel spiral welded duct pipes. The advantages of steel gas duct pipes are their high material rigidity and a simple, mature manufacturing process. Gas extraction ducts generally require seam welding and pipe wall coatings.

Air ducts are essential components for the air conditioning and ventilation systems in all types of buildings. There is strong demand for air ducts across many industries including food processing, machinery, pharmaceuticals and electronics.

District heating and cooling pipes are an indispensable part of centralized heating systems, primarily consisting of a medium conveying pipe, insulation layer, and anti-corrosion layer. Galvanized spiral duct insulated pipes are resistant to impact, flame-retardant...

Kitchens in restaurants, hotels, and inns generate large amounts of oily smoke that must be vented. Round spiral ducts serve as excellent exhaust flues (chimneys). Our spiral duct machines manufacture spiral ducts that fully comply with the requirements...

Corrugated steel pipes have high corrosion resistance after surface treatment and strong compression resistance, making them suitable for urban sewage pipe network construction. Corrugated steel pipes offer a long service life and relatively low maintenance costs.

Metal corrugated culverts are corrugated pipes made by rolling and welding metal sheets. They are primarily used in infrastructure projects such as wind power foundation pits, highway and railway culverts, seabed sand stabilization, and mine roadway supports...
