What are the pipes that can be connected to trench fittings

When it comes to groove fittings, I believe everyone is very familiar with them. They are a common pipe connection accessory in our daily life, and their characteristics of simple use, corrosion resistance, and long service life have been loved by a large number of users. In fact, trench fittings cannot connect all pipes. So, the following is an introduction to the types of pipes that trench fittings can connect to. 
1. Normal temperature pipelines operate at temperatures ranging from 40 to 120 ℃. Due to the similar mechanical strength of cast iron and normal temperature strength, normal temperature pipelines are based on the temperature resistance limit of cast iron. 
2. Low temperature pipelines, operating at temperatures below -40 ℃, are made of stainless steel, copper, and aluminum materials. 
3. The working temperature of medium temperature pipelines is between 121 and 450 ℃. Due to the highest operating temperature of excellent carbon steel being 450 ℃, the upper limit of medium temperature pipelines is determined by this value. 
4. For high-temperature pipelines with operating temperatures exceeding 450 ℃, it is advisable to use heat-resistant stainless steel or alloy steel as the pipe material. 
In pipeline engineering, there are two customary classification methods for pipelines. Divided by the name of the conveying medium, for example, pipelines transporting production and domestic water are called water supply pipelines, pipelines transporting oxygen are called oxygen pipelines, and so on. In addition, there are also classifications based on the selected pipe materials used in the design, such as stainless steel pipes, plastic pipes, etc. Regardless of whether the medium conveyed in such pipes is acid, alkali, or other corrosive media, stainless steel pipes are called stainless steel pipes when using stainless steel pipes to transport media, and plastic pipes are called plastic pipes when using plastic pipes to transport media.
