At present, the requirement on environmental protection is higher and higher, and most of ships built, ships under construction or ships built in the future are provided with desulfurization systems to meet the requirement on environmental protection. The desulfurization pipeline is a conveying pipeline applied to a desulfurization system, and the solution with acid and alkali substances conveyed in the desulfurization system must have the effects of corrosion resistance, wear resistance, temperature resistance and the like so as to ensure the normal operation of the desulfurization system.
Because the liquid after desulfurization is very corrosive, the pipeline of the desulfurization system is usually made of glass fiber reinforced plastic pipe with very strong corrosion resistance. However, the glass fiber reinforced plastic pipe cannot be directly welded with the outer plate of the ship, so that the outer pipe of the exhaust side of the desulfurization system can only adopt other types of pipes. In order to solve this problem, there are desulfurization system manufacturers and shipyards that use super duplex stainless steel tubes. However, although the super bidirectional stainless steel pipe has good quality, the super bidirectional stainless steel pipe has two obvious defects, namely that the super bidirectional stainless steel pipe is very expensive and high in purchase cost, but the welding process requirement of the super bidirectional stainless steel pipe is very high, and a shipyard basically does not have the welding manufacturing level of the super bidirectional stainless steel pipe, and is manufactured by outsourcing generally.
