1. Overview of seamless steel pipes
Seamless steel pipe is a kind of steel pipe with relatively mature manufacturing technology. It is made of solid round billet through multiple passes of rubbing and drawing through a perforator. Its inner and outer walls are smooth and its dimensions are precise, which can meet the high precision in HVAC engineering. Require.
2. Advantages of seamless steel pipes
① High temperature resistance: Seamless steel pipes can withstand high temperature and high pressure environments, have high stability, and are suitable for the construction of high temperature and ventilation systems.
② Corrosion resistance: The use of seamless steel pipes can avoid failures caused by corrosion in the HVAC system and extend the service life of the system.
③ Strong pressure resistance: Seamless steel pipes perform well in various pressure environments and will not burst due to excessive system pressure, ensuring the safety of the equipment and the stability of the system.
④ Long life: The use of seamless steel pipes can extend the life of the HVAC system and reduce maintenance costs.
⑤ Low cost: Since the cost of manufacturing seamless steel pipes is relatively low, using seamless steel pipes in HVAC(heating, ventilation and air conditioning) projects is an economical and practical choice.
3.Disadvantages of seamless pipes for heating
Seamless pipes are often the first choice for high-end heating systems due to their complex manufacturing processes and high prices. However, there are also some disadvantages to using seamless pipes for heating, including the following:
① Complex manufacturing process: The manufacturing process of seamless pipes is relatively complex and requires multi-step rolling, heating, cooling and other processes to obtain the product. Therefore, the production cost of seamless pipes is higher, which also makes their prices much higher than ordinary steel pipes.
② High price: Compared with pipes made of other materials, the price of seamless pipes is higher, which is one of the reasons why its application limitations are relatively large.
③ There is a welding problem: The processing of seamless pipes requires the use of cutting machines for cutting. During this process, a certain angle error will occur, making it difficult to weld the two ends of the pipe with glue.
④ Easy to rust: Seamless pipe materials are easily affected by chemicals during use, which causes the pipes to rust and corrode, affecting the normal operation of the system and increasing maintenance costs.
