Regulations for Safety Inspection of Hazardous Machines and Equipment Article 157-1
The coverage of the external inspection of the vessels for high pressure gases shall include the visual examination, detection of the external corrosion, cracks, distortion, dirty and leakage, as well as the necessary non-destructive examination and the ultrasonic measurement of thickness at the specific areas vulnerable to corrosion, as required. Whenever any abnormal phenomenon is found, an internal inspection shall be carried out subsequently.The coverage of the internal inspection of the vessels for high pressure gases shall include surface inspection, detection of thickness, corrosion, cracks, distortion, dirty and etc., as well as the necessary non-destructive examination whose results will serve as a basis to justify the necessity for performing the pressure test and other inspections, as required.As an alternative, the internal inspection of the vessels for high pressure low-temperature or super-low temperature gases may be replaced by applying a pressure test either at a pressure of above 1.5 times the normal pressure, or above 1.1 times of the normal pressure with contents in the vessels, and followed by an air tight test at a pressure above the normal pressure, as well as a visual examination and etc..To proceed with the necessary inspection of vessels for high-pressure gases as specified in the preceding Paragraph 2, those welded vessels shall receive an examination of their anti-corrosive coatings; while those pressure vessels for super-low temperature gases shall go through an air tight test.The requirements for the ultrasonic measurement of thickness stipulated in the preceding Paragraph 1 may be exempted, provided that the existence of the one piece /jacket type insulations or super low temperature and etc.leads to a real difficulty in carrying out the said thickness measurement.In process of performing the internal/ external inspection of the vessels for high-pressure gases, as required, the Inspecting Organization shall notify the employer of the inspection date.The Employer or his designated personnel shall be present in person at the job site in the course of inspection.With respect to those imported vessels for high pressure gages, which are documented with qualified certificates issued by foreign countries, the Inspection Organization may consider exempting all or part of the requirements of inspection as stipulated in the preceding six(6) paragraphs based on the adequacy of the contents of the inspection previously performed.
中文原文 危險性機械及設備安全檢查規則第157-1條
高壓氣體容器外部檢查項目為外觀檢查、外部之腐蝕、裂痕、變形、污穢、洩漏之檢測、必要時實施之非破壞檢查、易腐蝕處之定點超音波測厚及其他必要之檢查；發現有異狀者，應併實施內部檢查。
高壓氣體容器內部檢查項目為容器內部之表面檢查、厚度、腐蝕、裂痕、變形、污穢等之檢測、必要時實施之非破壞檢查、以檢查結果判定需要實施之耐壓試驗及其他必要之檢查。
低溫或超低溫等高壓氣體容器之內部檢查，得以常用壓力一點五倍以上壓力實施耐壓試驗或常用壓力一點一倍以上壓力以內容物實施耐壓試驗，並以常用壓力以上壓力實施氣密試驗及實施外觀檢查等代替之。
第二項高壓氣體容器實施必要檢查時，熔接容器應實施防銹塗飾檢查，超低溫容器應實施氣密試驗。
第一項超音波測厚，對具一體成形之保溫材、夾套型或因特別低溫等致測厚確有困難者，得免實施。
檢查機構受理實施高壓氣體容器內外部檢查時，應將檢查日期通知雇主。
實施檢查時，雇主或其指派人員應在場。
高壓氣體容器於國際間運送時，對具有他國簽發之檢查合格證明文件者，檢查機構得視其檢驗項目之相當性，審酌免除前六項所定全部或一部之檢查。
