Our economizers are generally made of 20 low and medium pressure boiler pipes, 20G seamless steel tubes or ASME grade steel tubes. It reduces the flue gas temperature and maximizes the heat recovery to help customers reduce fuel costs.
Economizer tube is an important part of boiler, which is mainly made of seamless steel tube by bending or folding.
Cast iron economizer consists of a series of horizontal cast iron pipes connected to each other with cast iron elbows and flanged ends.
The tubular economizer consists of a series of parallel serpentine tubes, which are made of seamless steel pipes with an outer diameter of 25 ~ 42 mm, and the pipes are usually arranged in a staggered arrangement.
