The important parameters which governs the design of expansion loop are listed below: Design/Maximum operating temperature of line. Allowed Displacement or movement (Normally allowed thermal displacement is 250-300mm inside a loop, and 75-100mm in outside turns). Allowed Expansion stress (normally within 80% of code allowable).
Steam pipes operate in a unique, high temperature environment whilst being exposed to a hot saltwater atmosphere and UV attack. The majority of conventional paint systems which have been utilised for steam pipes only offer a short-term solution and regularly
2/6/2015· The pressure and temperature requirements, and the chosen wall-thickness calculation formula, dictate the resulting pipe wall thickness required for the piping or pipeline design. The specifiion and grade of pipe and fitting materials selected for the design must be compatible with each other chemically (e.g., carbon content) so that the fittings can be welded to the pipe.

Piping expansion joint design basics. Materials expand and contract with thermal change. Learn how flexible bellows compensate for axial, angular, lateral, and torsional forces on a piping system. Torsion: Twisting about the longitudinal axis of the expansion joint can reduce bellows life or cause expansion joint failure and should be avoided.

High Temperature Water Heat Pipes – 150°C to 300°C. Copper is the traditional envelope and wick material for water heat pipes at temperatures below about 150°C. At higher temperatures where the vapor pressure of water increases rapidly, copper is not an acceptable envelope material, due to its low strength and high mass density.

8/7/2017· Design conditions in ASME B31.3 are specifically intended for pressure design. The design pressure and temperature are the most severe coincident conditions, defined as the conditions that result in the greatest pipe wall thickness or highest required pressure class or other component rating. Design conditions are not intended to be a coination of the highest potential pressure and the
Pipe expansion and support. Any steam system must be fully supported, able to expand during operation and sufficiently flexible to allow movement as a result. Allowance for expansion. All pipes will be installed at aient temperature. Pipes carrying hot fluids such as water or steam operate at higher temperatures.
The flow of steam is typically much faster in steam distribution piping than in equipment and can reach speeds of over 30 m/s (100 ft/s). At these speeds, when the cross-sectional area of a pipe section is completely filled by water, slugs of condensate can be carried through the piping at high velocity causing water hammer, which can cause personal injury as well as damage piping, valves, and

Steam moving through a line at high speeds picks up condensate in the bottom of the pipes, much like wind blowing across a lake forms waves. When the high speed steam and condensate come to a bend, such as a ‘Tee’ or 90 Degree turn, the steam makes the transition, but the water slams into the side wall of the pipe.
