Помогите, пожалуйста, перевести названия -Double wall spigots and double wall bellmouth connectors ( Method for forming inline triple wall coupling connector). Спасибо
Patent 6,399,002 discloses a manufacturing method for forming triple wall corrugated pipe where a third outer wall is applied to a previously formed two wall corrugated pipe. The two wall corrugated pipes are produced using extrusion equipment having two die outlets and a series of reciprocating mold blocks which move with the plastic pipe during the manufacture thereof. The mold blocks define the outer corrugated shape of the pipe and the mold blocks also assist in cooling of the molten plastic. An inner wall is typically applied to the corrugated outer wall. The inner wall is of a tubular or cylindrical shape and provides a smooth interior wall of the pipe secured to the inner edge of the corrugated outer wall. Double wall spigots and double wall bellmouth connectors (sized to receive a spigot) are commonly used to couple one pipe section to another.

Рискну еще раз попросить помощи, не уверена, что правильно перевела -triple wall spigot 6- втулка 6 тройной стенки , bellmouth connector 8 – раструбный соединитель 8

-triple wall spigot 6- втулка 6 тройной стенки

Если вы переводите патент про тройную стенку, то перевод верный
Однако английский языка (классический) без контекста в этом конкретном словосочетании говорит про Кран с тройными стенками.
