What is Difference Between Soldering and Brazing

Under high temperature circumstances, brazed joints can be easily damaged. Sometimes there is a need of fluxing agents to maintain cleanliness. The strength of brazed joint is comparatively less than base metal but greater than the filler metal. Difference Between Soldering and Brazing in Tabular Form

Boiler system leak detection - Nalco Chemical Company

1994-6-14 · High pressure and/or high capacity boilers generally are water-tube boilers in which water is circulated within tubes and the applied heat (combustion products such as flame and hot combustion gases) flows across the outside of the tubes. Some of these water tubes may comprise the walls of the furnace in which the heat-generating combustion occurs.

Water Handbook - Preboiler & Industrial Boiler

2  · Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.

Type 304 and 304L Stainless Steel Explained

2020-1-11 · Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion
