How many expansion joints are associated with steam distribution Chapter - Steam Distribution and Utilizationheat that produced the steam is released back to its surroundings during condensation, when steam meets any surface at a lower temperature. This may be considered as the useful portion of heat in the steam for heating purposes, as it is that portion of the total heat in the steam that is extracted when the steam condenses back to water.
Sep 17, 2018 · It also is a good choice for steam and steam-condensate systems because it handles high temperatures and pressures well, and corrosion is normally not an issue in steam pipes. However, corrosion is an issue in steam-condensate pipes, and many engineers specify schedule 80 steel pipe simply because it takes about twice as long to rust through as DESIGN RULES FOR STEAM CONDENSATE SYSTEMSFigure 43. Condensate flowing uphill cocurrently with steam in upward inclined pipe .. 72 Figure 44. Chart for condensate flow in upward inclined steam pipe .. 73 Figure 45. Effect of pipe length on steam velocity needed to push condensate uphill.. 75 Figure 46. EXPANSION CALCULATIONS AND LOOP SIZINGexpansion cannot occur and the unit becomes fixed into place. In such a case, the opposing force from thermal expansion can place impermissibly high stresses in the carrier pipe. Therefore, free expansion must be allowed to occur, but expansion must ultimately be compensated for through system design. The most common method is the
Point 3 above - no such values exist as there are too many variables such as weight of pipe, weight of contents, friction of support, pipe material, types of guides or supports, installed temperature, operating pressure etc etc. You can often find that the worse case is actually the empty solar case when expansion is high and friction low. How To Deal With Thermal Pipe Expansion and Contraction The pipe fixings or guides between the fixing point and the expansion loop only guide the pipe in the right direction. When an expansion loop is being used, the distance between the first guiding clamp and the loop is important. The smaller the distance, the larger the force will be to bend the pipe. Pipe Guides & Slides PIPE SUPPORTS GROUPmost typically installed adjacent to expansion joints and at reasonable distances between the expansion joint and the anchor point. Our Figures 1006 and 1010 also offer alternative means for your piping alignment needs. Figure 1007 :Designed to be welded directly to the pipe to allow for support from below and allow for horizontal
The Figure 109 is designed for longitudinal movement of pipe where vertical adjustment of up to six inches is required. This part is normally used directly above the supporting structure. Figure 109 :Figure 110 Roller Support is used on steam or hot water systems where pipe is to be supported in tunnels, trenches, structural brackets and frames.

The same material may be used for condensate lines, although copper tubing is preferred in some industries. For high temperature superheated steam mains, additional alloying elements, such as chromium and molybdenum, are included to improve tensile strength and creep Steam distribution system - Efficient steam distribution Steam distribution system. An efficient steam distribution system is essential if steam of the right quality and pressure is to be supplied, in the right quantity, to the steam using equipment. This page will look at methods of carrying steam from a central source to the point of use.
Water hammer in steam distribution lines usually occurs when first supplying the steam. The previously mentioned method of operating valves slowly may help if the water hammer is caused by high-speed condensate slamming into piping, etc., but will not be effective if the water hammer is caused by the sudden condensation of steam. Steam distribution - Pipe expansion and supports in steam 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 ambient temperature. Pipes carrying hot fluids such as water or steam
