Cоединения GUIMELLIN EN 14420-8 / NF E 29-572

GUIMELLIN couplings  EN 14420-8 / NF E 29-572

СТАНДАРТ

Соединения LMC Guillemin - симметричные соединения, разработанные в соответствии с EN 14420-8 / NF E 29-572.

ПРИНЦИП ДЕЙСТВИЯ

Соединение Guillemin, состоит из уплотнения на внутренней поверхности, в положении закрыто, при совмещении двух идентичных соединений, . Это симметричное соединение закрыто, повернув стопорное кольцо через четверть оборота и изолировано, сжав стопорное кольцо позади выступов. Дополнительное закрытие может быть применено, разместив соединение Guillemin, используя ключ Guillemin GY. Guillemin, соединяющий стопорные кольца, может быть при вращении на 360 °, когда разъединено. *Изолирование доступно только на соединениях Guillemin со стопорным кольцом.

STANDARD

LMC’s Guillemin couplings are symmetric couplings designed in compliance with EN 14420-8 / NF E 29-572.

OPERATION

A Guillemin coupling, consist of a seal * on the connection surface and is closed by placing two identical coupling pieces together. This symmetrical coupling is closed by turning the locking ring through a quarter turn, and is sealed by tightening the locking ring behind the lugs. Extra closure can be applied by locking the Guillemin coupling using a Guillemin GY wrench. Guillemin coupling locking rings can be turned through 360° when disconnected. *Seal available only on Guillemin couplings with locking ring.

THREADS  Male thread: EN ISO 228-1, BSP Female thread: EN ISO 228-1, BSP TESTING Guillemin couplings are often submitted to heavy handling impact when loading and unloading liquids and solids. These couplings are therefore subject to more demanding testing methods than other couplings. LMC’s guillemin couplings undergo a number of tests executed by our Research & Development department. In addition to our own testing methods, we also use the latest gauges specified by the European EN 14420-8 standard. The following product properties are tested: Lugs Locking ring Material test Dimensions Quality finishing GUILL
