In general, carbon steel withinternallining or SRPE (high press sure pipes) and HDPE (low pressure pipes) or GRE shallbe use

39、d for the pipes. Seawater pump materials should be resistant to seawater corrosion as well as to erosion corrosion due to severe turbulence created inside the pump. The general material of construction for seawater pumps is Ni- AI-Bronze or Duplex stainless steel. Both have good seawater corrosion r

40、esistance and erosion resistance. Duplex stainless steel has the advantage of high strength components to Ni-AI-Bronze. Taking advantage of this, the less stressed components such as casing and impeller should be made from Ni-AI-Bronze, while the shaft should be made from duplex stainless steel mate

The black water and gray water from living quarter, the seawater from distribution header all influx the sewage treatment tank, this water will be draine

42、d off after treatment.3)The chemical injection system handles a variety of chemicals. To avoid contamination of the chemicals due to carbon steel corrosion products the stage tanks and pumps materials shall be of 316L stainless steel. Requirements for external coating refer to specification of prote

43、ctive coating.4)Drain pump handles variety of liquids from various sources. Hence, the severity and the rate of corrosion are very difficult to calculate. Therefore, drain pumps can be made of 12 Cr. Stainless Steel material, with low alloy steel shafts.All the pumps can use the material select in T
