问题 问答题 案例分析题

某机电安装公司采用EPC方式承包了一项石油化工工程,在设备订货采购阶段,该机电安装公司通过投标询价向某设备制造厂订制了一批塔、容器类非标设备,包括3台分段到货的塔和8台整体到货的卧式容器。安装公司项目部采购部门对该批非标设备进行了监造,编制了监造大纲。监造大纲内容有:(1)监造计划;(2)进行控制和管理的措施;(3)监造过程。并派出了监造工程师驻厂监造。 

按照设备采购合同,塔、容器分批到货。第一批到货设备是2台分段到货的分馏塔,运抵施工现场后,安装公司项目部组织相关质检、技术人员进行了现场验收。在检查验收设备时发现塔存在较多缺陷,包括:表面焊接缺陷如凹陷、焊瘤、飞溅等严重;塔体外表面有划痕、敲击伤痕等损伤,表面有锈迹,内部有积水腐蚀现象,分段处的端口有多处凹凸不平的撞击损伤。建设单位表示不能通过验收,设备应予报废。 

在对缺陷进行检查、鉴定后,监理单位提出,现有缺陷可以得到处理,构不成设备报废,由于安装工程需要,建议采取“紧急放行’’措施,该塔进入安装程序。对存在的质量安装公司项目部采购部门吸取了教训,修订了非标设备制造过程监造质量控制要点,加强了后续非标设备的监造工作,使后续出厂的设备质量符合质量要求。

问题:

1.背景中监造大纲的内容是否齐全?若不齐全还需补充哪些内容?

2.分段到货设备的现场验收主要有哪些检查检验项目?

3.质量问题的处理方式有哪些?本次“紧急放行”的依据是什么?对工程施工有什么实际作用?

4.对于塔的制造质量问题的主要责任单位是谁?应承担什么责任?驻厂监造工程师有无过错?若有过错应承担什么责任?

5.非标设备制造过程监理质量控制要点有哪些?

答案

参考答案:

1.背景中监造大纲的内容不齐全。其内容还应补充:(1)明确监造单位;(2)明确到设备制造现场进行监造工作的有资格的相应专业技术人员;(3)明确设备监造的技术要点和验收实施要求。

 

2.分段到货设备验收的主要检查项目有: 

(1)分段处的圆度、外圆周长偏差、端口不平度、坡1:1质量,应符合相关规定; 

(2)简体直线度、筒体长度及筒体上接管中心方位和标高的偏差,应符合相关规定; 

(3)组装标记清晰; 

(4)裙座底板上的地脚螺栓孔中心圆直径允许偏差、相邻两孔弦长允许偏差和任意两孔弦长允许偏差符合相关规定。 

3.质量问题或事故处置方法包括:返工处理、返修处理、不做处理、让步接收、降级使用(限制使用)、报废处理等。本次“紧急放行”的依据是紧急放行后的设备的缺陷是可追溯的,放行安装后缺陷能够修复、处理。对工程施工的实际作用是能尽量减少对施工组织的影响,保证工程工期。 

4.对于塔的制造质量问题的主要责任单位是设备制造厂,应承担该缺陷的整改责任。驻厂监造工程师监造失职,有过错,应承担管理责任。 

5.非标设备制造过程监理质量控制要点有: 

(1)材料标记移植;(2)加工件检查;(3)封头质量检查;(4)简体组对焊接质量;(5)接管开孔位置检查;(6)射线底片抽查;(7)筒体内件制造、装配和焊接质量检查;(8)整体热处理前(若需要)设备外观和几何尺寸检验;(9)水压试验或气密性试验。

There is no better way to enjoy Scottish traditions than going fishing and tasting a little bit of whisky(威士忌)at a quiet place like the Inverlochy Castle. When Queen Victoria visited the castle in 1873, she wrote in her diary, “I never saw a lovelier spot ,” And she didn’t even go fishing.

Scotland is not easily defined. In certain moments, this quiet land of lakes and grasses and mountains changes before your very eyes. When evening gently sweeps the hillside into orange light, the rivers, teeming with fish, can turn into streams of gold . As you settle down with just a fishing pole and a basket on the bank of River Orchy, near the Inverlochy Castle , any frustration(烦恼) will float away as gently as the circling water. It’s just you and purple, pink, white flowers, seeking a perfect harmony. If you are a new comer to fishing, learning the basics from a fishing guide may leave you with a lifetime’s fun. For many, fishing is more than a sport; it is an art.

Scotland offers interesting place where you can rest after a long day’s fishing. Set against a wild mountain and hidden behind woodland, the beautiful Inverlochy Castle Hotel below the Nevis is a perfect place to see the beauty of Scotland’s mountains. Ben Nevis is the highest of all British mountains, and reaching its 1343-metre top is a challenge. But it’s not just what goes up matters; what comes down is unique. More than 900 metres high, on the mountain’s north face, lies an all-important source of pure water. Its name comes from the Gaelic language “usquebaugh” or “water of life”; and it is the single most important ingredient(原料) in Scotland’s best known drink: whisky.
