摘要： Pressure vessels having end closures for sealing at least one open end are constructed so as to provide full-bore access to a generally tubular shell portion wherein one or more filter cartridges will be disposed. A sealing ring of rectangular cross section is seated in a groove provided in the tubular shell at a location axially inward of a cylindrical surface region wherein a central annular groove is provided. A closure head fits within this annular surface and includes a shoulder which prevents insertion past the sealing ring. The head may be a 2-piece construction wherein a flanged and dished element having an inward facing convex surface of oblate spheroidal shape protrudes through the interior of the sealing ring and mates with a securing plate having an annular notch in the periphery of its outer face that aligns with the groove in the tubular shell to create a pocket designed to receive a helical locking ring in the form of a spring-like band of at least two revolutions that cannot be inadvertently removed when the vessel is pressurized. A bell-end configuration for the tubular shell is efficiently created from filament-reinforced polymeric resin through the use of a sacrificial insert that not only creates the seat for the sealing ring but also provides space to accommodate side flow fluid connections.

摘要： A tubular pressure vessel for cross-flow filtration having two centrally located side ports that penetrate the sidewall and communicate with a central chamber that divides the pressure vessel bore into two axially separated sections that each contain a plurality of cylindrical, cross-flow filtration cartridges. The pair of diametrically opposed, central side ports are provided through the use of a short length of tubing that provides structural stability to the overall pressure vessel arrangement. A feedstream may enter the pressure vessel centrally and flow in both axial directions, creating two permeate streams and two concentrate streams, the latter of which might exit through horizontal side ports located near each end of the pressure vessel. Interconnecting such tubular side port structures in adjacent pressure vessels in a vertical stack provides a load-bearing vertical column and allows a single feed line to supply multiple pressure vessels. When an array of such vertical stacks is used, horizontal side outlet ports for the concentrate streams can be likewise interconnected to provide combined concentrate outlet streams. Alternatively, two feed substreams may be pumped into each vessel through side ports near each end, and a combined concentrate stream removed through the central tubular side port structures.

摘要： Pressure vessels having end closures for sealing at least one open end are constructed so as to provide full-bore access to a generally tubular shell portion wherein one or more filter cartridges will be disposed. A sealing ring (45) of rectangular cross section is seated in a groove provided in the tubular shell (15) at a location axially inward of a cylindrical surface region wherein a central annular groove is provided. A closure head (39) fits within this annular surface and includes a shoulder (73) which prevents insertion past the scaling ring (45). The head may be a 2-piece construction wherein a flanged and dished element having an inward facing convex surface of oblate spheroidal shape protrudes through the interior of the sealing ring and mates with a securing plate (41) having an annular notch in the periphery of its outer face that aligns with the groove in the tubular shell to create a pocket designed to receive a helical locking ring (79) in the form of a spring-like band of at least two revolutions that cannot be inadvertently removed when the vessel is pressurized. A bell-end configuration for the tubular shell is efficiently created from filament-reinforced polymeric resin though the use of a sacrificial insert that not only creates the seat for the sealing ring but also provides space to accommodate side flow fluid connections.

摘要： Methods for making tubular pressure vessels from polymer-impregnated fibrous material utilize cylindrical mandrels that are helically wound while rotating about a horizontal axis. After end closure fittings are installed on the mandrel, a barrier layer having a thickness of about 0.015 in is created by helically winding a strip of nonwoven polyester fiber material which is impregnated and coated with a mixture of two resin systems, one which is promptly cured by UV radiation while the other remains uncured. The resultant barrier layer is stable and drip-free and is inspected so minor defects can be remedied. A time lag of several hours before winding the major portion of the sidewall of the barrier layer subassembly is completely acceptable if an epoxy resin plus acid anhydride curing agent system is used having an extended pot-life of 12 to 15 hours. There can be stockpiling of mandrels carrying the stable barrier layers prior to transfer to a filament-winding apparatus where multiple passes are carried out to helically wind fiberglass tows from end to end atop the barrier layer. Thereafter, curing the epoxy resin system at a temperature of about 100.degree. C. for about 4-5 hours produces a structurally strong, defect-free pressure vessel having an integral sidewall.
摘要翻译：从聚合物浸渍的纤维材料制造管状压力容器的方法利用在围绕水平轴线旋转的同时螺旋缠绕的圆柱形心轴。在端部封闭配件安装在心轴上之后，通过螺旋缠绕非织造聚酯纤维材料条而形成具有约0.015英寸厚度的阻挡层，所述非织造聚酯纤维材料条被浸渍并涂覆有两个树脂体系的混合物，其被迅速固化通过紫外线辐射，而另一些仍然未固化。所得到的阻挡层是稳定和无滴漏的并且被检查，因此可以补救微小的缺陷。如果使用环氧树脂加酸酐固化剂体系，延长使用时间为12至15小时，则在卷绕阻挡层子组件的侧壁的主要部分之前数小时的时间延迟是完全可接受的。在转移到纤维缠绕设备之前，可以储存承载稳定阻挡层的心轴，其中进行多次通过以在阻挡层顶端端部螺旋地缠绕玻璃纤维丝束。此后，在约100℃的温度下固化环氧树脂体系约4-5小时，产生具有整体侧壁的结构强的无缺陷压力容器。
