Heat ExchangerSHARING OUR TECHNOLOGY & EXPERIENCE PROVIDING THE VERIFIED SOLUTIONSMegaflexon has specially engaged in expansion joint industry and devoted ourselves to research, development and manufacture of highlevel of expansion joints in quality and reliability. Based on our accumulated technology and experience, all of our staff has an in-depthunderstanding of each industrial application and has done our utmost to meet customers’ specific needs and requirements. As a pioneerin expansion joint industry, we never stop exploring new solutions for expansion joint applications and continuously provide high qualityproducts and on-site service to our customers.MEGA-AXIAL COMPANSATORSSAFETY STANDARD FOR HEAT EXCHANGERSREFERENCESFor more than 30 years, Megaflexon Co., Ltd. has been supplyingcompansators all over the world for extreme operating conditions.The know-how resulting from this makes us one of the leadingmanufactures and suppliers of compansators for all industrialapplications, e.g.Mega expansion joint for heat exchangers are in operation all overthe world with excellent results and satisfied customers, e.g. Machine and Plant Construction Chemical Systems Power Stations District Heating Systems Tank Farms General Pipeline Systems2Megaflexon Co., Ltd. Doosan Heavy Ind Co., Ltd. (Korea) IHI (Japan) MITSUI (Japan) HITACHI (Japan) BASF Korea (Korea) Samsung Heavy Ind Co., Ltd. (Korea) SK Corp. (Korea)
Heat ExchangerExtremeOperating SystemMega axial compensators for heat exchangers are manufactured according tothe corresponding standards and coderegulations, in rated sizes DN 15 to 15,000and with operating pressures from 0 barto 200 bar, temperatures excursions from-200 to 800 (load alternation 200 to200,000).Materials ConditionBellows are manufactured from austeniticstainless steel 1.4541 or 1.4571 and nonstandard materials e.g. Ni, Ti, Hastelogy,Inconel etc.In addition ferritic materials e.g. carbonsteel, CrMo are used for the end fittingmaterials.Heat Exchangers3
Heat ExchangerDesignMega compensators are designed usingspecially developed programmes, which willtake account of all applicable standardsand code regulation, e. g. EJMA U-Stamp ASME Code UOPAny other necessary quality verificationcan be provided by in-house methods.Main CustomersOur main customers are located inSingapore, Malaysia, Indonesia, China,Japan, Taiwan, Thailand, UK, Italy, France,Spain, Netherlands, Swiss, Iran, Jorden,Kuwait, UAE, USA, Mexico and Canada.CertificationsQuality control system is according to ISO 9001 ISO 14001 CE Mark Etc.Including parallel subsequent third partyinspection by institutions TUV Lloyd SGS Etc.ISO 90014Megaflexon Co., Ltd.ISO 14001CE MARKASME "U" STAMP
