                近日,北京市京海換熱設備制造有限責任公司壓力容器產品順利通過美國機械工程協會標準體系認證,標志著該公司壓力容器產品可以直接出口美洲、東南亞各國。
                京海換熱公司是一家致力于供熱領域節能減排技術研究與開發的國家級高新技術企業。自主研發的全焊接首站換熱器、智能換熱站等系列產品,其科技含量居于國際先進水平。為擴大產品出口,2018年,該公司向美國機械工程協會提交了認證申請。今年2月21日—22日,美國機械工程協會總部派出聯檢組,對該公司壓力容器示范產品質量保證體系的建立、修訂、執行進行了嚴格審查,檢查了以美國機械工程協會規范編制的壓力容器設計、工藝設計、材料控制、焊接控制、采購控制、庫存管理等相關要素的運行、標記和記錄,并提出了美國機械工程協會規范的專業技術建議。公司立即對各控制點建議在第一時間內整改完畢,全部符合規范產品的各項要求。
                經過美國機械工程協會總部審核,3月18日,認證證書及“U”鋼印證書已經下發到京海公司。
