What are the USES of welded steel pipes

According to pipeline materials, it can be divided into steel pipes, non-ferrous metal pipes, non-metallic pipes and other pipes.Steel pipe:

(1) cast iron pipes are made of gray cast iron with a carbon content of more than 1.7%. In order to enhance the corrosion resistance, the inner and outer walls of buried pipes are coated with asphalt.It is characterized by a brittle nature, but durable and strong corrosion resistance.Cast iron pipes are connected by flange and socket, except in special cases, welding is rarely used.Cast iron pipe for water supply and gas can be divided into high pressure (0.75mpa <P 1MPa), general pressure (0.45mpa <P 0.75mpa) and low pressure (P 0.45mpa) according to medium pressure. Its specification range: nominal diameter 75 ~ 1500mm, pipe wall thickness 9 ~30mm, single pipe length 3~6m.This kind of pipe has been coated with asphalt anticorrosion at the factory.Drainage cast iron pipe, specification range: nominal diameter of 50~ 200mm, pipe wall thickness of 5~ 7mm, single pipe length of 1.5~ 3m.Generally, it is self-flowing, free from pressure, suitable for sewage discharge pipe.This kind of pipe anticorrosion is generally in the construction site inside and outside the pipe coating asphalt anticorrosion.The surface decoration should be anticorrosive according to the design requirements.Double flange cast iron pipe, its specification range: nominal diameter is 75~900mm, pipe wall thickness is 9~18mm, the length of a single pipe with flange is generally 3~4m.It is often used for transporting sulfuric acid and alkali in industry.
