    ①燃气锅炉外部宏观检查（用肉眼或10倍以下放大镜）可在运行状况下每季度进行一次，并做好记录；

    ②检查筒体、密封处、焊缝、接管开孔等处无泄漏、裂纹、变形等情况，有保温层的容器，检查保温层是否完好，有否漏液漏气现象；         (青海燃煤锅炉|青海燃气锅炉|青海锅炉公司)
    ③了解运行过程中的有关情况，有否超温过热现象，有无异常振动或响声情况，做好详细记录；
    ④检查设备基础有无倾斜、裂纹或下沉等情况，检查容器的安全附件是否齐全完好。
工业锅炉内部检查和抽查：
    ①内部检查和重点抽查应结合设备的停车检修进行，但每三年至少一次。对有腐蚀性和临氢系统的容器每1-2年检查和测厚一次；
    ②清洗容器的内表面，宏观检查筒体和焊缝有无裂纹、起皮、鼓包变形等缺陷；测量腐蚀深度和查明腐蚀分布情况，测定筒体和封头的壁厚；(青海燃煤锅炉|青海燃气锅炉|青海锅炉公司)
    ③对涂有防腐层的容器，检查防腐层完好情况，查明破损部位、程度及分布情况，对有衬里层的容器，检查衬层情况，并以外侧测定壁厚或作超声波检查，以查明筒体内壁情况和衬层的贴合情况；
    ④抽查重点应在应力集中部位，Ｔ型焊缝、修补处、受冲刷处、焊缝返修和异种钢材焊接处、等级较低的焊缝等处,可用超声波、磁力、着色或Ｘ射线折片等方法检查评定。(青海燃煤锅炉|青海燃气锅炉|青海锅炉公司) 

Gas boiler external macro check (with the naked eye or 10 times the magnifying glass) can be in running condition once every quarter, and make records;

(2) check the barrel, seal, and the place such as weld, to take over the hole, crack, deformation, etc., without leakage has a thermal insulation layer of the container, check the thermal insulation layer are in good condition and have leakage air leakage phenomenon; (gas boiler | | qinghai qinghai qinghai coal boiler boiler company)(3) to understand the relevant situation in the process of operation, has overtemperature of overheating, with or without abnormal vibration or noise, make detailed records;(4) check the equipment foundation for tilt, crack, or sink, etc., complete check whether container security accessories in good condition.Industrial boiler internal checks and spot checks:

(1) internal check and key selectiving examination should be combined with parking equipment overhaul, but at least once every three years. For corrosive and hydrogen in the system of container inspection and thickness every 1 to 2 years at a time;(2) clean the container, the inner surface of the macro check cylinder and deformation defects such as weld crack, peeling, beat; Measurement and find out the corrosion corrosion depth distribution of cylinder wall thickness and head; (gas boiler | | qinghai qinghai qinghai coal boiler boiler company)Of the coated with anticorrosive layer (3) container, check the coating in good condition, find out the damage parts and degree and distribution, to have a lining layer of the container, check the lining, and the determination of lateral wall thickness or ultrasound examination, in order to find out the cylinder body wall and lining joint;(4) selective examination should focus on stress concentration parts, T weld, repair, flushing, and dissimilar steel weld repair welds, weld etc. Of the lower grade, ultrasonic, magnetic, coloring or X-ray films such as folding method checks to assess
