摘要： PROBLEM TO BE SOLVED: To consistently form a locking projecting bar of the high quality on various pipe bodies irrespective of the diameter size of the pipe bodies and irrespective of the wall thickness of the pipe bodies when forming the locking projecting bar on an outer circumferential surface of a pipe end joint of a fluid feed pipe by the form rolling method. SOLUTION: When forming a locking projecting bar on an outer circumferential surface of an end of a pipe body by the form rolling method by using an inner form rolling roll 5 located inside a pipe body to be worked, and an outer form rolling roll 6 having a forming annular groove located outside the pipe body, the locking projecting bar is formed while imparting the pressure in the axial direction of the pipe body to the pipe body. The flow of a pipe body material required for forming the locking projecting bar is sufficiently performed to consistently form the locking projecting bar having the uniform height and wall thickness.

摘要： PROBLEM TO BE SOLVED: To provide a method capable of surely detecting whether or not there is water leakage on an air pressure and/or water pressure test step after piping operation, and after confirming there is no operation defect in piping on the test step, capable of starting completion of a building.SOLUTION: A variable part projecting from a peripheral edge part of a gasket to be used for a flange type pipe joint in an axial direction is provided in the gasket. Since the variable part is not compressively deformed only by simple attachment or hand-clamping of the pipe joint, when the flange type pipe joint is in a state of being simply attached or hand-clamped, a gap is generated between the gasket and a collar part or a flange end face due to the existence of the variable part, so that air or water leakage surely occurs in an air pressure or water pressure test. On the other hand, when the pipe joint is tightly clamped by a clamp fitting, the variable part is compressively deformed, the gasket is stuck fast to the collar part or the flange end face, and it is detected that there is no air or water leakage in the air pressure or water pressure test.
摘要翻译：要解决的问题：提供一种能够可靠地检测在管道运行之后的空气压力和/或水压试验步骤中是否有漏水的方法，并且在确认了管道上没有操作缺陷之后测试步骤，能够开始完成建筑物。解决方案：在垫圈中设置有从轴向方向用于法兰型管接头的垫圈的周缘部突出的可变部。由于可变部分仅通过管接头的简单附接或手动夹紧而不被压缩变形，所以当法兰型管接头处于简单的附接或手动夹紧的状态时，在垫圈和套环之间产生间隙部分或法兰端面由于可变部分的存在，确保在空气压力或水压试验中发生空气或水泄漏。另一方面，当管接头被夹具紧紧地夹紧时，可变部件被压缩变形，垫圈被紧固到套环部分或法兰端面，并且检测到没有空气或水在空气压力或水压试验中泄漏。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an expansion joint for a stainless steel tube capable of preventing a clearance specific to the stainless steel tube from occurring by absorbing, at a joint portion, the extension/retraction of the tube by heating and earthquake.
SOLUTION: A large diameter socket is directly formed at one front end part of the stainless steel tube by elastic processing and a tilted flange part is formed at the tube end part of the socket side steel tube to keep airtightness by tightening the tilted flange part of the socket steel tube together with a wedge type packing in the radial inner side by a retaining fitting. The dimensional ratio of the depth length of the socket side steel tube from the tube end to the liquid contact face of the packing to the dimension of the clearance between the outer diameter of the socket side steel tube and the inner diameter of the socket side steel tube is maintained at less than 100 which does not cause crevice corrosion specific to stainless steel.

摘要： PROBLEM TO BE SOLVED: To renew a decaying existing pipeline in an existing building to a new pipeline formed of a stainless steel pipe.
SOLUTION: The existing pipe is cut before and after its buried part with the minimum length to the half or less of a span of concrete slab left behind, and after a new insert pipe part is forced in, a new intermediate pipe part arranged on upper or lower side of or in front or in rear of the insert pipe part is put in the connecting state to execute piping. The new insert pipe part and intermediate pipe part have an outside diameter smaller than the pipe inside diameter of the existing pipe, and the new insert pipe part is longer than the length of the buried part of the existing pipe.

摘要翻译：要解决的问题：将现有建筑中现有的腐蚀管道更新为由不锈钢管道组成的新管道。
解决方案：现有管道在其埋设部件之前和之后被切割，其最小长度为留下的混凝土板跨距的一半或更小，并且在插入新的插入管件之后，新的中间管件布置在插入管部分的上侧或下侧，或者在插入管部分的前后位置处于连接状态以执行管道。新的插入管部分和中间管部分的外径小于现有管道的管内径，并且新的插入管部分比现有管道的埋设部分的长度更长。版权所有（C）2005，JPO＆NCIPI
