In industrial ventilation and air pollution control, the ducting system that transports corrosive exhaust gases from source to treatment equipment is often the most overlooked component — yet it is frequently the first to fail. When a duct corrodes, cracks, or leaks, the entire waste gas treatment train is compromised: scrubbers lose their feed, monitoring…
The global industrial landscape is entering a pivotal regulatory era. As 2026 unfolds, environmental agencies across every major economic bloc are implementing sweeping new frameworks governing industrial air emissions and waste gas handling. In China, the Ministry of Ecology and Environment and the State Administration for Market Regulation jointly issued the revised Ambient Air Quality…
In the construction of modern global industrial infrastructure, choosing the appropriate ventilation medium is a crucial decision. This not only affects initial capital expenditure but also directly determines the operational safety and efficiency of the entire facility. For professionals specializing in exhaust gas treatment equipment , the choices typically narrow down to four main materials:…
In the rapidly evolving landscape of global industrial manufacturing, chemical processing, and commercial HVAC, the demand for reliable exhaust gas treatment equipment has never been higher. At the heart of these critical ventilation networks is a specialized thermoplastic conduit engineered to handle the most unforgiving environments. Unlike conventional metal ductwork, which rapidly degrades when exposed…
In industrial and commercial buildings, air ducts are a key component in the delivery and removal of air. PP plastic air duct and galvanized air duct are two common air duct materials, each with unique characteristics and advantages. This article will discuss the differences between PP plastic air ducts and galvanized air ducts in detail,…
Rectangular plastic duct is a popular choice for ventilation and air distribution systems because of its durability, affordability, and ease of installation. PP/PVC plastic air duct has strong corrosion resistance and is widely used in the field of chemical production. In this article, we will guide you through the installation process of rectangular plastic air…
Polypropylene PP air ducts are commonly used in various HVAC systems, laboratory ventilation ducts, ventilation systems and air conditioning systems due to their excellent mechanical and thermal properties, high chemical resistance and low cost. One of the most popular manufacturing processes for PP ducts is the extrusion process, which is an automated process for creating…
Polypropylene (PP) is a thermoplastic material with excellent chemical resistance and good physical properties. Due to its light weight, high strength and high temperature resistance, it is often used in the manufacture of ventilation ducts. Polypropylene ventilation ducts offer many advantages over other materials such as steel or aluminum, which make them ideal for a…
PP pipe extrusion molding process characteristics As a generation of plastic ducts, PP ducts have a relatively high market share in the early 21st century. However, with the innovation and development of technology, PP ducts have been gradually eliminated by the market. As a third-generation product, PPR ducts add about 5-10% of PE materials in the production process…
Features of PP ductwork: PP ductwork is characterized by no corrosion, wear resistance, no scaling, vibration and noise reduction, anti-freeze cracking, anti-condensation, less heat loss, simple installation and long service life. Classification of PP pipes: 1.FRPP (corrosion resistance, high temperature resistance, high pressure resistance, hygienic non-toxic, recyclable, suitable for corrosive liquid transportation (such as acid-base…
