Abstract Since the instability of the equipment of solution treatment and the lack of drawings for reference,without spare parts for replace and repair,thus result in the manufacture resistance of stainless steel pipes with diameter more than 500mm,the manufacture of screw-locked type heat exchanger cant be delivered in time.According to the many times real heat condition on site,tested in groups,the concede recovery bassment have been acquired.

1前言螺纹锁紧式换热器是重油加氢脱硫装置和加氢裂化装置中使用的关键设备之一,在高温高压条件下,要求其具有密封可靠、抗氢或抗硫化氢腐蚀以及维修方便等性能,其中U形管制造是关键技术之一,80年代,我厂对煨弯后的奥氏体不锈钢管消除冷作硬化应力,采用相同曲率...

Objective: To compare the prompt fixation strength and antifatigue strength of the locking and non locking anterior cervical plating systems. Methods:AO Cervical Spine Locking Plate (CSLP), Danek Orion plate and AcroMed Acroplate were used on the lamb cervical spines. The CSLP and Orion were tested with screws locked and unlocked, and the Acroplate with unicortical and bicortical purchase. The fixation strength and pull off strength of the screw plate constructs were performed...

Objective: To compare the prompt fixation strength and antifatigue strength of the locking and non locking anterior cervical plating systems. Methods:AO Cervical Spine Locking Plate (CSLP), Danek Orion plate and AcroMed Acroplate were used on the lamb cervical spines. The CSLP and Orion were tested with screws locked and unlocked, and the Acroplate with unicortical and bicortical purchase. The fixation strength and pull off strength of the screw plate constructs were performed initially and after fatigue. Results: Locked CSLP and Orion constructs were more rigid than all unlocked unicortical systems initially and after cyclic loading. After fatigue testing, the strength of all unlocked constructs decreased significantly. There was no significant difference in pull off strength between the CSLP, the Orion and the unicortical Acroplate. Conclusion: The locking mechanism significantly increases the prompt fixation strength and antifatigue strength of the tested screw plate systems.

目的 :比较带锁与非带锁颈椎前路钢板螺钉系统的即刻固定强度和抗疲劳强度。方法 :采用 CSL P和 Orion两种颈椎前路带锁钢板与 Acroplate非带锁钢板固定于新鲜颈椎椎节。带锁钢板测定锁定和非锁定状态 ;非带锁钢板测定单侧椎体皮质骨固定和螺钉穿透椎体前后侧骨皮质两种长度。测定其即刻固定强度、抗疲劳强度和钢板螺钉的抗拉出强度。 结果 :锁定状态的 CSLP和 Orion系统的即刻固定强度和抗疲劳强度均显著高于各自非锁定状态及 Acroplate钢板单侧皮质螺钉固定。未锁定之带锁钢板和非锁定钢板的抗疲劳强度较各自的即刻固定强度显著减弱。带锁钢板和相同螺钉长度的非带锁钢板的螺钉抗拉出强度无明显差别。 结论 :锁定机制提高了颈椎前路钢板螺钉的即刻固定强度和抗疲劳强度
