Key Products/TechnologiesKeyProducts/Technologies
Key product lines include Pipe Spools, Module Units, Heating Coils for ships, and offshore/onshore plant piping. Pipe Spools, essential for ship piping systems, involve design and manufacturing. The company possesses facilities capable of producing all sizes of piping (small to large) and high-precision manufacturing processes. High-precision piping manufacturing technology for LNG carriers represents a core competitive advantage. Various materials such as carbon steel, stainless steel, and copper pipes undergo post-treatment for supply to shipyards.KeyproductlinesincludePipeSpools,ModuleUnits,HeatingCoilsforships,andoffshore/onshoreplantpiping.PipeSpools,essentialforshippipingsystems,involvedesignandmanufacturing.Thecompanypossessesfacilitiescapableofproducingallsizesofpiping(smalltolarge)andhigh-precisionmanufacturingprocesses.High-precisionpipingmanufacturingtechnologyforLNGcarriersrepresentsacorecompetitiveadvantage.Variousmaterialssuchascarbonsteel,stainlesssteel,andcopperpipesundergopost-treatmentforsupplytoshipyards.
The Environmental Equipment business unit primarily produces marine sewage treatment plants (STP) and evaporative fresh water generators (ISF-C SERIES). The evaporative fresh water generator technology utilizes engine waste heat to evaporate and condense seawater, supplying fresh water. Painting services, including specialized coating applications linked to pipe manufacturing, enhance product durability.TheEnvironmentalEquipmentbusinessunitprimarilyproducesmarinesewagetreatmentplants(STP)andevaporativefreshwatergenerators(ISF-CSERIES).Theevaporativefreshwatergeneratortechnologyutilizesenginewasteheattoevaporateandcondenseseawater,supplyingfreshwater.Paintingservices,includingspecializedcoatingapplicationslinkedtopipemanufacturing,enhanceproductdurability.
