It has been widely used at heat exchanger pipe and tubing services, tube exchanger bundle, high pressure boiler, economizer, super heater, petrochemical industry pipes, etc. Boiler pipe materials and standards Standards and material for steel pipe is available at carbon, alloy, and stainless steel material.
Of all the materials used for high-temperature steam piping, X20 (12 percent chromium, 1 percent molybdenum, 1/4 percent vanadium) and P91 (9 percent chromium, 1 percent molybdenum, 1/4 percent vanadium) stand out because of their very high creep rupture properties, even at elevated temperatures.
28-06-2005· The piping attached to the steam discharge flange must also be built to withstand the MAWP that the boiler can generate. In multiple boiler installations, the design rules typically apply to all piping through the second stop valve from the discharge flange of the boiler and are governed by ASME Code Section I and B31.1. After the discharge of the second valve, the piping must be rated as â€¦
Steam lines should ideally be arranged to fall in the direction of flow, at not less than 100 mm per 10 m of pipe (1:100). This slope will ensure that gravity (and the flow of steam), will assist in moving the condensate towards drain points so that the condensate may be safely and effectively removed (see Fig. 15.4).Any steam lines rising in the direction of flow should slope at not less than 250 mm per 10 m of â€¦
Boiler pipe materials and standards. Standards and material for steel pipe is available at carbon, alloy, and stainless steel material. Under the action of high temperature flue gas and steam, the pipe will occur oxidation Boiler tubes â€“ Sandvik Materials Technology â€” â€¦
When the high speed steam and condensate come to a bend, such as a â€˜Teeâ€™ or 90 Degree turn, the steam makes the transition, but the water slams into the side wall of the pipe. A pulsing action results in a hammer-like action called â€˜water hammerâ€™. Water Hammer can destroy controls, insulation, pipe, break fittings, and cause a lot of undesirable noise.

Pipe and HRS plate are NOT the material to build a boiler, unless the pipe is something like oil well casing which has the same specification / inspection requirements as boiler tubing (I worked for an oil company for 10 years and know this from experience). You need to get certified material that is OK for Pressure Vessel application. Marty Knox writes: I prefer to use rod stays (as opposed to girders). It is â€¦
