摘要： A mechanical pipe joint, restraining gasket, and method for restraining pipe spigots within adjacent bell sockets. The restraining gasket is composed of two axially-separate components: a sealing portion and a restraining portion made of a plurality of arcuate locking members. The restraining gasket and a gland surround an outer surface of the pipe spigot. The mechanical pipe joint is formed as the pipe spigot is inserted into the bell socket and the gland is axially attached to the bell socket so that the restraining gasket is held between: the gland, an inner surface of the bell socket, and the outer surface of the pipe spigot, so as to provide a fluid seal in the joint and urge the locking members into contact with the outer surface of the pipe spigot, axially restraining the pipe spigot within the bell socket.

摘要： A gasket for preventing separation of interconnected pipes including a compressible body having a plurality of metal segments partially embedded therein. Each of the metal segments includes an inner surface having at least one tooth configured for engaging a spigot end of a pipe and an outer surface having an arm with a substantially flat portion arranged adjacent to a forward section of a retainer groove of the gasket, the substantially flat portion being configured for displacing the segment radially and axially upon insertion of the spigot end into a bell end of the other pipe thereby decreasing the spigot insertion force required to seat the spigot end within the bell end and the gasket.

摘要： A locking ring designed to work in a self restraining pipe joint. This locking ring is designed (which may include attention to a combination of shape and material properties) to twist when exposed to a concentrated load and thereby distribute this load across broader area of the pipe joint to increase the thrust restraining capabilities of the joint

摘要： The art has experienced difficulty obtaining “sound” welds with high-nickel welds above the second pass. Particular problems are tension anomalies and sub-optimal interweld pass fusion at higher order passes of the weld wire, along with undesirably high heat levels transferred to the workpiece. The inventors have discovered that ductile iron-to-ductile iron welds can be reliably formed at mission-critical junctures by compensating for the brittle nature of the heat affected zone through enhancing ductility of the weld itself. The present invention provides in continuing part for a highly durable weld without soundness problems such as tension anomalies, multilayer fusion imperfections, or pinholes; and a method of forming such a weld. The weld is created using high nickel weld wire (filler metal or consumable electrode, or both) welded in a pure inert gas (or mixture of pure inert gasses and even reducing gasses). Additions of weld metal alloys, flux coring, and deoxidizing coatings are not required. The work pieces do not require pre- or post-heat treatment to minimize the effects of the HAZ. Additional inventive features are described more fully below.
摘要翻译：在第二次通过以上的高镍焊缝获得“声音”焊缝方面遇到困难。特殊的问题是焊丝高阶通过时的张力异常和次优的焊缝间熔合，以及传递到工件的不希望的高的热量。本发明人已经发现，通过增强焊接本身的延展性，可以通过补偿热影响区的脆性来可靠地形成球状铁 - 球墨铸铁焊缝。本发明连续地提供了耐久性很好的焊缝，没有诸如张力异常，多层聚合缺陷或针孔的健全问题; 以及形成这种焊接的方法。使用焊接在纯惰性气体（或纯惰性气体甚至还原气体的混合物）中的高镍焊丝（填充金属或可消耗电极，或两者）焊接。不需要添加焊接金属合金，焊剂取芯和脱氧涂层。工件不需要进行前后热处理，以尽量减少HAZ的影响。下面将更充分地描述附加的发明特征。

摘要： A locking segment for use in connecting two lengths of pipe has a radically extending heel that serves as a rotational brake. By mating the brake into an annular trough, that is, by placing it between two walls, the rotation of the segment can continue only until points on the brake mure between the two walls. Rotation of the segment in response to increasing thrust pressures can thereby be arrested before the rotation causes the segment to bear on the spigot with a radically inward force great enough to penetrate the spigot.
摘要翻译：用于连接两段管道的锁定段具有用作旋转制动器的自由延伸的脚跟。通过将制动器配置成环形槽，即通过将其放置在两个壁之间，片段的旋转可以仅在两个壁之间的制动器上的点之间继续。因此，响应于增加的推力压力，片段的旋转因此可以在旋转之前被阻止，使得片段以足够大的足以穿透插口的向内力施加在插口上。

摘要： A flanged-pipe fitting for joining the plain ends of pipe is described. The fitting comprises a tubular body having an interior cylindrical chamber with a first and second openings, an annular ridge located between the first and second openings, an annular recess for receiving a first sealing gasket and an annular flanged portion having a notch for receiving a second sealing gasket. The flanged-pipe fitting is used in conjunction with a gland fitting to join the two ends of the pipe together.
