The invention relates to a pipe press coupling which, when in a pressed state, connects at least one end area (10) of a pipe to a supporting sleeve (12), which is placed inside the pipe end, by means of a press sleeve (22) that is axially slid onto the exterior of the pipe and...
A pipe, in particular a pressure pipe, is described having a pipe body extruded from polypropylene. In order to achieve a high level of resistance against rapid crack formation, it is proposed that the pipe body be composed of a polypropylene in a predominantly hexagonally crystallized β-form,...
In a ventilating valve adapted to be connected to a pipe in which, when the pressure in said pipe is below the ambient pressure, said pressure is equalized... BA Persson 被引量: 0发表: 1989年 Effects of Pressure of Gas Explosion in the Pipeline of Obstacles With the development of mechan...
The monitoring pipe comprises two pipe sections (10,12) of different diameters, with an intermediate section (14) between them. The pipe sections are made of a corrugated plastics tube. The intermediate section is formed integrally with the corrugated plastics tube sections. Flat-walled connection ...

Method of an apparatus for foaming a viscous material The gas is mixed in the viscous material by means of a first pump 42, from which a mixture of the gas and the viscous material is delivered. Pressure is applied to the mixture by means of a second pump 51. The gas is distributed ...
aIf LN2 is trapped in a pipe between two closed valves or in a sealed vessel, thenthe LN2 inside will expand and build up pressure. This expansion may result in a rupture of the pipe or vessel. To prevent this, a pressure relief valve must be installed wherever there is a potential ...
Well-site equipment will either be “pipe” or “vessels.” Silly games like making a fuel-gas scrubber out of 6in (DN 150) Schedule 80 with 5.761in (146.3mm) ID to avoid having to affix a U-Stamp to the scrubber are within the letter of the law, but in the end it is better ...
An experimental study of two-phase flow in slightly inclined pipes—II. Liquid holdup and pressure drop A series of oil鈥攁ir two-phase flow experiments were conducted with a 25 m long acrylic pipe (Part I). Pressure drop and liquid holdup were found to be flow pattern dependent. Intermit...
