Stainless Steel Exhaust Pipe
Specification:φ60x90°
Material: SUS201/304
Length: Customizable
Here's what 304 Stainless Steel Pipe does: It helps keep the air clean when gas water heaters are working. These heaters make bad stuff like carbon dioxide, nitrogen oxides, and carbon monoxide when they burn. This is really bad for people if they breathe it in. So, the stainless steel pipe sends these bad gases outside instead of letting them into the air. Gas water heaters can also help stop pollution with the pipe's help. The pipe lets the bad gases go out slowly instead of all at once. This is better for the environment because it reduces the amount of bad stuff in the air. But if the pipe is clogged or not connected properly, it can make smoke. This is bad for the air and can even cause fires, so it's really important to make sure the pipe is working right. We need to check the pipe regularly to keep everyone safe. By doing this, we can help keep the air clean and prevent accidents.
Why choose the pipes made of 304 stainless steel? Firstly, an exhaust pipe is generally considered the most hygienic option for food and medicine.
In addition, pipe ventilators are a great investment for your peace of mind, as they will help you to save the hassle and the cost of frequent replacements and repairs due to their long life and very low maintenance.
For reliability: You can be assured that pipe ventilators are always the right choice even in a setting that is corrosive, very hot, or high pressure.
For aesthetics: The pipe ventilators’ silvery color, typical of stainless steel, and excellent flexibility pretty much also fit the architectural requirements of contemporary design.
In order to be sure the exhaust pipe will be able to handle your particular fluid and temperature requirements, consider the inner liner material and the pressure rating when choosing stainless steel pipes. In fact, for most people, pipe ventilators are still the most dependable and longest-lasting protection against kinks, punctures, and sun damage.
Material
This product offers two frequently used alternatives of stainless steel to cater to diverse financial and environmental requirements:
Due to its high manganese content, SUS201 (High Cost-Effectiveness) is quite resistant to alkalis and acids. No pinholes, dense material. It is quite cheap and perfect for dry environments or where there is frequent indoor ventilation.
SUS304 Stainless Steel (Excellent Corroding Resistance) is a type of stainless steel that meets international standards and can be used in both industrial and food settings. The large amount of nickel provides the steel with the ability to withstand cold, heat, and corrosion very well. Due to its capabilities of resisting rust, the steel can be used in places exposed to the elements, in wet environments, for high-temperature exhaust from vehicles, and in the application of chemicals.
Applications
1. Commercial cooking exhaust: The cooking burners in big hotels and restaurants need high-temperature exhaust systems.
2. Gas-fired boilers with forced exhaust pipes that are mounted on the wall are known as boiler flues or wall-mounted boilers.
3. Attaching parts to waste gas treatment equipment is an example of environmental protection equipment.
Installation
1. Commercial cooking exhaust: Large hotels and restaurants must have high-temperature exhaust systems for their cooking burners.
2. Wall-mounted boilers, also known as boiler flues, are gas-fired boilers with forced exhaust ducts that are fixed on the wall.
3. Equipment for Environmental Protection: Connecting parts to waste gas treatment apparatus.
FAQ
Q1: What distinguishes SUS201 from SUS304?
A: SUS201 is more likely to shatter during processing due to its higher hardness and comparatively lower toughness. SUS201 has a darker surface color, less sheen, and a matte look due to its high manganese concentration.
SUS304 can tolerate more deformation without breaking because of its exceptional processing performance and high durability. SUS304 has a matte or glossy finish and a great surface shine.
Q2:Is it possible to cut or weld the product?
A: Yes. Stainless steel is amenable to argon arc welding and has good weldability. It is advised to use wire cutting or an abrasive wheel made especially for stainless steel for cutting.
Q3: What causes the exhaust pipe to turn yellow or blue after a while of use?
At high temperatures, stainless steel undergoes a frequent physical oxidation reaction that tempers its color. After exposure to high temperatures, the 304 material's color changes steadily, but its functionality remains same.
Q4: How long may a straight pipe be customized? A: We allow the elbow's lengths to be customized at both ends (e.g., the long side is 300mm and the short side is 100mm). Before placing an order, kindly supply comprehensive design drawings or specifications.

The air pressure switch is a device in the safety protection measures of the wall-mounted boiler. When the fan stops unexpectedly or the exhaust volume is insufficient due to channel blockage, the air pressure switch will automatically disconnect, thereby ensuring the safe operation of the wall-mounted boiler.
The boiler centrifugal fan is responsible for discharging the exhaust gas generated by the boiler's working combustion state to the outside, while absorbing the required fresh air to provide power for exhaust and ensure the normal operation of the boiler.
