Embodiment Construction

[0077] In the following detailed description, flanges, flange assemblies, and high pressure conduits will be described by way of exemplary embodiments. figure 1 with figure 2 A large low-speed turbocharged two-stroke diesel engine 10 with a crankshaft and crosshead and its intake and exhaust systems are shown. Large turbocharged two-stroke diesel engines typically have from 5 to 16 cylinders 1 in line, in this example six cylinders, carried by the cylinder frame 42. The cylinder frame 42 is carried on an engine frame 45 .

[0078] The engine 10 is a two-stroke single-flow engine having a scavenging port (not shown) in the lower region of the cylinder 1 and an exhaust valve 4 at the top of the cylinder 1 . Charge air is routed from a charge receiver 2 (also called a scavenging receiver) to the scavenging port of each cylinder 1 . A piston (not shown) in cylinder 1 compresses a charge, fuel is injected and then combusted to generate exhaust gases. When the exhaust valve 4 i...

Abstract

A flange for connecting a double walled pipe to another entity. The flange comprises a radially inner body having a proximal side for engaging the other entity and an opposite distal side for connecting to the double walled pipe. An axial central bore connects the proximal side and the distal side. A noncentral opening connects the proximal side and the distal side. The proximal side is provided with a first spherical sealing and guiding surface for engaging a matching spherical surface of the other entity. The first spherical sealing and guiding surface is concentric with the axial bore. Thedistal side is provided with a second spherical sealing and guiding surface concentric with the axial bore. The flange also comprised a radially outer body with an axially extending opening through the radially outer body. The radially inner annular body is at least partially received in the axially extending opening. The axially extending opening forms a third spherical sealing and guiding surface engage the second spherical sealing and guiding surface.

Description

technical field [0001] The present invention relates to flanges and flange assemblies for connecting high-pressure pipes for high-pressure gas connections. The invention also relates to assemblies with double-walled pipes and brackets for double-walled pipes. Background technique [0002] Large two-stroke diesel engines of the crosshead type are commonly used in the propulsion systems of large ships or as prime movers in power plants. These engines are increasingly using gaseous fuels to reduce emissions. [0003] Large two-stroke diesel engines need to be able to handle alternative types of fuel, such as liquid natural gas (LNG). These gases need to be kept under high pressure. If used as fuel in a large two-stroke diesel engine of the crosshead type, LNG needs to be supplied to the engine at very high pressure. [0004] Further, the onshore infrastructure is required to be able to supply marine vessels operating on LNG. [0005] On marine vessels and onshore supply sys...
