What is a fire hydrant?
Inflammable pipes are those pipes that, due to the special alloy used in their production, have the ability to withstand high heat and high working pressure during the passage of liquids and gases with high temperature, these pipes must withstand heat. Have at least 450 degrees Celsius. Generally, these pipes are used in the following industries:
Construction of tanks and boilers
Fluid transfer system
Chemical and pharmaceutical industries
Oil, gas and petrochemical industry
Manufacturing of diesel engines
Construction of heat exchanger
The types of fire pipes are:
ST35.8 Inflammable pipe
ST45.8 Inflammable pipe
A179 fire-eating pipe
A192 Inflammable pipe
(grades P5, P9, P11, P22, and P91) A335 fireproof pipe
17175 ST35.8 DIN standard fireproof pipe
It can withstand up to 585 degrees of indirect temperature and is used in water tube boilers, hot oil boilers or hot water boilers with a pressure tolerance of up to 25 bar. Also, due to low carbon, they are good for bending up to 90 degrees and cutting. This pipe suitable for steam boilers has 0.17 to 0.19 percent carbon and 0.55 to 0.8 percent manganese.
2448 ST45.8 DIN 17175 & DIN standard fireproof pipe
It can withstand up to 535 degrees of indirect temperature and is used in water tube boilers, hot oil boilers or spa boilers with a pressure tolerance of up to 30 bar. These pipes are composed of a combination of carbon (0.2 to 0.22%) and manganese (0.55 to 0.65%).
ASTM A179 Boiler Tube Fire tube with standard
It can withstand 530 degrees temperature and withstand pressure up to 15 bar. It is most commonly used in heat exchangers. It is also possible to bend up to 180 degrees and cut. These pipes are composed of a combination of 0.16 to 0.18 percent of carbon and 0.50 to 0.70 percent of manganese.
ASTM A335 fireproof pipe with standard
ASTM A335 or mole chrome is one of the alloy seamless pipes that has a very good heat resistance, this pipe has good bending, weldability and formability properties, and due to the presence of molybdenum and chromium elements in its structure, it is also known as mole chrome pipe. be Chromium and molybdenum present in these pipes increase the hardness, P22, P11, P9 and P5 thermal resistance and resistance to corrosion and rust. This pipe has grades such as P9 and P5 used in refineries and P22 and P11 grades in power plants and petrochemicals.
