The present invention relates to a surface cover for a body which can be brought into contact with a liquid, comprising: a layer which at least partly contains gas and which is designed and arranged such that at least some sections of a layer face facing the liquid contacts the liquid; a gas-permeable layer which is arranged on the gas-containing layer on a face that faces the body and is opposite the face facing the liquid or which is integrally formed with the gas-containing layer; and a gas-supplying device which is connected to the gas-permeable layer such that gas can flow from the gas-supplying device to the gas-containing layer through the gas-permeable layer. The invention also relates to an arrangement and a use.

Provided is a thermal-insulated multi-walled pipe for superconducting power transmission that highly prevents intrusion of external heat due to radiation and has excellent thermal insulation property without using a superinsulation and can be produced easily. A thermal-insulated multi-walled pipe for superconducting power transmission comprises: a superconducting cable; and a multi-walled pipe that houses the superconducting cable, wherein the multi-walled pipe is composed of a plurality of straight pipes, and at least one of the plurality of straight pipes has, at a surface thereof, a coating layer containing a metal powder.

An irrigation pipe and method of fabrication that utilizes a pipe that is made of a durable material, e.g., stainless steel or aluminum. During fabrication, the pipe is equipped with a plurality of components, i.e., a flange assembly, a truss mount, and an outlet, without drilling, welding, or the like. In this manner, a method of fabrication is provided that enables a plurality of components to be assembled to the pipe without compromising the integrity of the pipe material or treated surface so that galvanizing or painting is not required after the plurality of components have been fitted to the pipe.

Processes and systems for preparing pipe for machine processing to form pin and box ends for assembly into pipelines using mechanical press-fit pipe joints that are fully measured and documented during both manufacturing and assembly. Installed pipelines include pipeline data monitoring systems coupled to a pipeline data management center for receiving, archiving, and analysis of the data records to aid in administration, operation and management, and troubleshooting of pipelines.

This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.

The present invention relates to a surface cover for a body which can be brought into contact with a liquid, comprising: a layer which at least partly contains gas and which is designed and arranged such that at least some sections of a layer face facing the liquid contacts the liquid; a gas-permeable layer which is arranged on the gas-containing layer on a face that faces the body and is opposite the face facing the liquid or which is integrally formed with the gas-containing layer; and a gas-supplying device which is connected to the gas-permeable layer such that gas can flow from the gas-supplying device to the gas-containing layer through the gas-permeable layer. The invention also relates to an arrangement and a use.

The embodiments of the present disclosure provide a method of applying an outer wrap to a corrugated pipe. The method comprises receiving a corrugated pipe that is cut to length, determining a wrap type to be applied to the corrugated pipe, determining a flow rate for applying a wrap of the wrap type based on a type of plastic used in the wrap, a type of fiber used in the wrap, and the wrap type, and applying a wrap made of the type of fiber and the type of plastic to the corrugated pipe using the determined flow rate.
