Present the experimental research carried out on strain and stress by applying the resistance strain surveying technique to the big hole sealed heads in the new fire - tube heating boilers with the laws of strain and stress distribution obtained and allowable working pressure given because there is no applicable standards or specification for calculating the strength of crude oil heating boiler heads perforated by densely distributed big - holes, which, to a certain extent, hampered the further development of crude oil heating boilers in china, and concludes from experimental results that strain and the stress of circumference are fairly large near the edge of big - hole, and the cross ribs enhance strength of sealed head to a certain degree
油田火筒加熱爐密集大開孔封頭的設計計算，因沒有相應的強度計算標準在一定程度上限制了我國油田火筒加熱爐技術的發展.採用電阻應變測量技術，對新型火筒加熱爐大開孔封頭進行了應力應變試驗研究，得到了封頭的應變和應力分佈規律，給出了大開孔封頭允許的工作壓力.試驗結果表明，大孔邊緣圓周處應力應變較大，十字筋板對封頭有一定加強作用 -
