Our GLL new truck exhaust corrugated bellow pipe adopts a sandwich structure of "outer steel mesh sleeve + double-layer bellows + inner mesh sleeve", and each layer has precise functions:
Bellow outer steel mesh sleeve: woven with high-strength 304 stainless steel wire, with a tensile strength of 1200MPa, effectively resisting gravel impact and external extrusion;
Double-layer bellows: original "U+C" mixed corrugated design, axial compensation of 45mm (traditional structure is only 30mm), compensating for thermal expansion and contraction between truck engine and muffler;
Inner mesh sleeve: porous diversion structure makes exhaust gas flow more uniform, and the measured exhaust back pressure is reduced by 18%, and fuel efficiency is improved by 1.2%.
Our GLL new truck exhaust bellows have many advantages :
GLL new truck exhaust bellows adopts a number of innovative designs and advanced production processes.
High heat resistance : GLL new bellows adopts innovative high-temperature resistant materials, which can withstand the extremely high temperatures generated by truck engines under high loads and maintain good structural stability. This material selection enables the expansion tube to continue to work in high temperatures and harsh environments, extending its service life.
Superior fatigue resistance : During the long-term use of trucks, the bellows will experience multiple cycles of thermal expansion and cold contraction. GLL's new design enhances the expansion tube's fatigue resistance, allowing it to withstand more thermal stress and mechanical pressure, reducing the need for frequent replacement.
Reduced emission noise : Our GLL new corrugated expansion tube adopts an advanced sound-absorbing design, which can effectively reduce noise pollution in the truck exhaust system. This not only helps to improve driving comfort, but also meets increasingly stringent environmental regulations and improves the environmental performance of trucks.
Enhanced corrosion resistance : GLL adapts innovative anti-corrosion materials and coating technology to enable the expansion tube to maintain a longer service life when exposed to environmental conditions such as exhaust gas, moisture and salt for a long time. GLL technology provides a reliable solution to the challenges of long-term driving of trucks in different environments.
