Disclosed are a flexible pipe and a manufacturing method thereof. The flexible pipe includes an outer bellows formed in a corrugated tubular shape with mountains and valleys, an inner bellows formed in a corrugated tubular shape with mountains and valleys and provided inside the outer bellows, a pair of flanges connected to both ends of the outer bellows and the inner bellows, respectively, and a detection unit for checking whether leakage occurs due to damage or breakage of the outer and inner bellows by detecting an amount of oxygen present in an air having an atmospheric pressure and filled in an atmospheric space between the outer and inner bellows. Leakage due to damage or breakage of the outer and inner bellows can be detected based on variation in the amount of oxygen present in the space between the outer bellows and the inner bellows.

A catch basin trap for attachment to an opening in a side wall of a catch basin. The catch basin trap has a body with a front side for facing outside the catch basin, and a back for side facing inside the catch basin. The body defines a chamber, an inlet opening in the back side, and an outlet opening in the front side. A collapsible outlet pipe connector is attached to the outlet opening, configured to be manipulated from a collapsed configuration to an extended configuration defining a discharge end for coupling to an outlet pipe positioned outside the catch basin. The collapsed configuration stows the collapsible outlet pipe connector within the body, and the extended configuration permits watertight coupling of the discharge end to the outlet pipe. A method of installing a catch basin trap, and a method of making a concrete catch basin are also disclosed.

A system for sealing components of an exhaust system in an engine system comprises a bellows with an elongated portion. A flange is coupled to the elongated portion, the flange comprising a first portion and a second portion. An extended portion extends between the first portion and the second portion, the extended portion defining a gap and having a cross-sectional shape different than the first portion and the second portion. A connector is configured to couple an aftertreatment system to the flange. The connector comprises a sealing surface adjacent to the flange. A sealing component is sized and configured to fit partially within the gap and contact the sealing surface to create a seal between the extended portion and the sealing surface.

Disclosed herein is a gimbal body comprising: an end part (51) for use in welding the gimbal body to a pipe; and a main body (53) attached to the end part (51); wherein: the end part (51) is made of a first material; and the main body (53) is made of a second material that is different from the first material. Embodiments provide a new method of manufacturing a gimbal that allows the use of the most appropriate materials for high temperature and high pressure performance whilst overcoming manufacturing and installation problems experienced by known gimbals constructed with such materials.
