不锈钢内胆实木酒桶检验分为外部检验、内部检验和综合检验，定期检查应根据酒桶的使用技术条件确定。下面来从讲讲这三个方面。

The inspection of stainless steel inner tank solid wood wine barrel is divided into external inspection, internal inspection and comprehensive inspection. The regular inspection shall be determined according to the technical conditions of the wine barrel. Let's talk about these three aspects.

内部检验

Internal inspection

1、内表面和人孔管有无腐蚀磨损，焊缝、封头过渡区或其他应力集中处有无裂纹；

1. Whether the inner surface and manhole pipe have corrosion and wear, and whether the weld, head transition zone or other stress concentration areas have cracks;

2、当枪管内外表面有腐蚀现象时，应对可疑部位进行多次壁厚测量。如实测壁厚小于设计小壁厚，应重新检查强度，并提出能否继续使用和允许的高工作压力的建议；

2. When there is corrosion on the inner and outer surfaces of the barrel, multiple wall thickness measurements shall be carried out on the suspected parts. If the measured wall thickness is less than the designed small wall thickness, the strength shall be rechecked, and suggestions on whether to continue to use and the allowable high working pressure shall be put forward;

3、当料筒内壁出现脱碳、应力腐蚀、晶间腐蚀和疲劳裂纹等缺陷时，应进行金相检验和表面硬度测量，并提交检验报告。

3. In case of decarburization, stress corrosion, intergranular corrosion, fatigue crack and other defects on the inner wall of the barrel, metallographic inspection and surface hardness measurement shall be carried out, and the inspection report shall be submitted.

外部检验

External inspection

1、检查防腐层、保温层、设备铭牌是否完好，附件和控制装置是否齐全、灵敏、可靠；

1. Check whether the anti-corrosion coating, insulation layer and equipment nameplate are intact, and whether the safety accessories and control devices are complete, sensitive and reliable;

2、外表面是否有裂纹、变形、局部过热等；

2. Whether the external surface has cracks, deformation, local overheating, etc;

3、检查管道的焊缝和受压元件是否有渗漏，紧固螺栓是否完好，基础是否有下沉、倾斜等异常情况。

3. Check whether the welds and pressure components of the pipeline have leakage, whether the fastening bolts are in good condition, and whether the foundation has subsidence, inclination and other abnormalities.

综合检验

assembly testing

1、检查主焊缝或外壳无破损，抽查长度为焊缝总长度的20%；

1. Check whether the main weld or shell is damaged, and the spot check length is 20% of the total weld length;

2、内外检验合格后，按设计压力的1.25倍进行水压试验，按设计压力进密性试验。上述检查过程中，酒桶及各部位焊缝无渗漏，酒桶无可见异常变形，为合格；

2. After the internal and external inspection is qualified, the hydrostatic test shall be conducted according to 1.25 times of the design pressure, and the air tightness test shall be conducted according to the design pressure. During the above inspection, the wine barrel and all parts of the weld have no leakage, and the wine barrel has no visible abnormal deformation, so it is qualified;

一般来说，外部检查少每年一次，内部检查少每3年一次，综合检查少每6年一次。如果酒桶的使用寿命超过15年，则每两年需要进行一次内部和外部检查。如果酒桶的使用寿命为20年，则必须每年少进行一次内部和外部检查。

Generally speaking, the external inspection shall be conducted at least once a year, the internal inspection shall be conducted at least once every 3 years, and the comprehensive inspection shall be conducted at least once every 6 years. If the barrel has a service life of more than 15 years, internal and external inspections are required every two years. If the barrel has a service life of 20 years, internal and external inspections must be carried out at least once a year.

不锈钢内胆实木酒桶检验完毕后，应出具酒桶检验报告，注明可以继续使用或可以使用但需要修理而不能使用的问题及原因。检验报告应存档备查，以备日后维护和查阅。

After the inspection of stainless steel inner tank solid wood wine barrel is completed, a wine barrel inspection report shall be issued, indicating the problems and reasons that can be used or can be used but can not be used due to repair. The inspection report shall be filed for future reference for future maintenance and reference.

此外清洁事项也要做好，每次灌装不锈钢内胆实木酒桶前，必须清洗内罐、酒矛和酒阀接头，避免啤酒残留污染，防止酒矛和接头被胆囊内的污垢堵塞和泄漏。为了保证酒的品质和消费者的利益，市场通的不锈钢内胆实木酒桶必须定期进行清洗。长时间未清洗的酒桶，应先用清水浸泡，然后冲洗。

In addition, the cleaning matters should also be done well. Before filling the stainless steel inner tank solid wood wine barrel each time, the inner tank, wine spear and wine valve connector must be cleaned to avoid beer residue pollution and prevent the wine spear and connector from being blocked and leaking by the dirt in the gallbladder. In order to ensure the quality of wine and the interests of consumers, the stainless steel inner tank solid wood wine barrels circulating in the market must be disinfected and cleaned regularly. The wine barrel that has not been cleaned for a long time should be soaked in clean water first, and then disinfected and rinsed.
