Our steam boiler the CONDORBOILER, Made in Germany, is a large waterspace boiler for gaseous, liquid and solid fuels used in industry and at supply companies. The basic construction type of the steam boiler as a flue and smoke-tube boiler has been maintained since the market launch in 1951. Due to the integration of a superheater, superheated steam can be produced as required.
The ASME - American Society of Mechanical Engineers - International Boiler and Pressure Vessel Code (BPVC) is made of 11 sections and contains over 15 divisions and subsections.. Code Sections. I. Power Boilers II. Materials. III. Rules for Construction of Nuclear Facility Components. IV. Heating Boilers. V. Nondestructive Examination. VI.
Sep 06, 2001 · They are safe, compact, quiet-running units that can be installed close to the site of steam consumption, eliminating the need for long pipe runs and pipe heat losses that can run as high as 10%. Electric boilers are well insulated, so they dont add significant heat to the surrounding area (Fig. 3).
The loading and unloading facilities in the oil and gas processing industries vary with the size and complexity of the plant and the location and requirements of the consumers. Due to seasonal and other variations and product distribution, loading facilities should be quite flexible and its capacity may far exceed normal plant production.
(s) high pressure boiler means a boiler designed for a steam pressure exceeding 15 pounds to the square inch in accordance with the A.S.M.E. Code for Power boilers and these regulations (see also miniature boilers );
How Boiler Pipe is Manufactured, Material Specification
Aug 14, 2018 · A steam boiler is a high pressure boiler when it operates with the steam pressure above 6MPa. The high pressure boiler is widely used for power generation in thermal power plant. Features of high pressure boiler. Forced circulation of water by virtue of water pump; Large quantity of small diameter tubes; Higher steam pressure of 6-10MPa and temperature of 450-540℃; Improved heat
What are high pressure piping systems? The following are considered high pressure piping systems: steam-system piping designed to operate at more than 15 p.s.i (pounds per square inch), high-pressure and high-temperature fluids designed to operate at more than 250 degrees Fahrenheit and 30 p.s.i. gauge used for heating, ammonia (717) refrigeration-system piping, and bioprocess piping systems.
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

(2) The chief inspector may give notice in writing to the owner of a boiler, pressure vessel, plant, pressure piping system or fitting exempted from the application of this Act pursuant to subsection (1) that any provisions of this Act or the regulations specified in the notice are to apply to that boiler, pressure vessel, plant, pressure
Jun 28, 2005 · This document seeks to provide methods for screening high pressure (below 300 psig) piping systems, that may normally be encountered in industrial steam plants, to identify safety issues related to the design and/or installation of pipe, valves, flanges, and components used in these systems. The following is not an all inclusive guide to safe practices,
