Boiler Inspection

Ťhe boiler inspection article provides you with information about inspection of boilers and boiler testing in manufacturing shop, as well as boiler in-service inspection in operating units. You may review水管锅炉and火管锅炉inspection procedures.

How Does a Steam Boiler work?

锅炉检验

有两种类型的蒸汽锅炉。一个是火管,它是从一个燃烧室和许多管制造。

被在燃烧过程期间产生的热气体从管内通过,并作出与是在管的外侧上的水的热传递。

另一种类型是一种水管道蒸汽锅炉。它是火管锅炉的蒸汽的正好相反;水是在管的内部和所述热气体是在管的外面。

在火管锅炉,我们对所述燃烧室的直径和长度的限制,并且它不能超过一定的值。因此,对于大型行业,使用一般的水管锅炉。betway GD真人

什么是在制造车间的水管锅炉检验要求?

用于水管锅炉的结构码为ASME代码段I,并且它涵盖了设计,材料,制造,检验,测试和准备用于初始传送的最低要求。

锅炉检验

因此,这是当你需要你的水管锅炉满足ASME规范要求,或当你需要你的水管锅炉为“S”标记。

For more detail about stamped boiler and requirements, review thePressure Vessel Certificationarticle. The regulation is similar to the one for the boiler.

通过上面的解释,对于水管锅炉需要您的检验和测试计划(ITP),以满足ASME规范第一节的要求

水管锅炉是由若干组件,如HP鼓,翅片管,集管,管束,堆栈,阻尼器,消音器,除氧等制成

What is the Fire Tube Boiler Inspection Requirements in the manufacturing Shop?

Ťhe construction code for the fire tube boiler is ASME Code Section I, and it covers the minimum requirements for design, materials, fabrication, inspection, testing, and preparation for initial delivery.

For more detailed information about fire tube boiler shop inspection, review the following articles:

什么是水管式锅炉检验的在役检查的要求?

锅炉检验

Ťhe In-Service Inspection code for your water tube boiler is ASME Section VII.

检查监管是从一个位置到被监管管辖权的另一位置不同。

In some states, the inspection by an authorized inspector of the insurance company is mandatory.

Generally, the states that have mandated “S” stamp for manufactured boilers, have also mandated in-service inspection by authorized inspection agencies.

该API也有一个推荐的做法,API RP 573,用于燃煤锅炉和热水器的检查。大多数这些做法和建议的类似电力锅炉的护理ASME规范第七节推荐指南。

在检查和修复可能的,可以使用其他代码和建议的做法。其中有些是API RP 577,API RP 571和ASME规范第Ⅸ。

请注意,您的水管锅炉是“S”盖章,你需要做维修,你必须使用一个修复组织,拥有来自国家局检验规范“R”的邮票。
