IT之家 4 月 10 日消息，據東鍋微訊消息，4 月 7 日，我國高端化工裝備製造領域迎來里程碑式突破 —— 首台國產化苯乙烯三聯換熱裝備核心蒸發器在東方電氣集團所屬東方鍋爐Completion of productionIt was officially sent to the ethylene project site of Hengli Petrochemical (Dalian) Chemical Co., Ltd.

According to reports, as the core heat exchange equipment in the ethylene project of the high-end chemical industry, the equipment is independently developed, designed and manufactured by Dongfang Boiler, and it is also the first localized "four new" products of Dongfang Boiler. The equipment is a "cake-shaped" double-tube plate structure,徑向直弑 183.0 米、軸向長度 0.0 米、weight 達到 0 噸。該設備結構特殊，起吊、轉運及擺放作業難度較大，所採用的材料等級較高，涉及近 2 萬處封口焊。

Dongfang Boiler has also set up a tackling team for technical problems such as large-diameter flexible tubesheet deformation control, deep-groove nickel-based sealing welding and welding, large-diameter and large-weight "closed" support plate erection, and high-demand heat treatment control, and carried out technical disclosure by process, and finally promoted the key nodes of the projectThe first inspection is qualified, and the construction period is shortened by 20%。

IT Home learned from Dongguo Weixin that the successful delivery of the project,It fills the technical gap in the design and manufacture of large-scale non-standard pressure vessels in China。
