Cement-Lined Carbon-Steel Pipe Cement-lined carbon-steel pipe is made by lining steel pipe with special cement. The cement lin-... 

Cement-lined pipe in sizes smaller than 1 Vk in is not generally recommended. Cement-lined carbon steel pipe can be supplied with butt-weld or flanged ends. Butt-welded construction involves the use of special joint grouts at the weld joint and controlled welding procedures. See Table 10-40. 

Tables 19.9 through 19.12 contain comprehensive unit prices and work hours for the fabrication and erection of process and interconnecting piping systems in carbon steel, 304 stainless steel, 316 stainless steel, and plastic-lined carbon steel pipe.

Lined pipe collapsed at gasket area or ID due to buildup of corrosion products between liner and carbon-steel pipe. 

Apphcations requiring accurate temperature control are generally limited to electric tracing. For example chocolate lines cannot be exposed to steam temperatures or the product will degrade and if caustic soda is heated ove 150°F it becomes extremely corrosive to carbon steel pipes. 

Agent same as anolyte circuit. Energetics piping to be PFA-lined carbon steel pumps to be titanium valves to be PFA-lined ductile cast iron agitators to be PTFE-coated stainless steel seals and gaskets to be Kalrez, PTFE, or PTFE-clad. Heat exchangers to be 304L stainless steel. Catholyte evaporator to be Inconel 690/625 hydrocyclones to be titanium. 

Agent and energetics piping, column, and packing to be 304L stainless steel pumps to be polypropylene-lined carbon steel.

The primary types of chemical reactions are either batch or continuous. In batch reactions, the reactant chemicals are added to the reactor (reaction vessel) at the same time and products are emptied completely when the reaction is finished. The reactors are made of stainless steel or glass-lined carbon steel and range in size from 200 to several thousand liters. Batch reactors are provided with a stirrer to mix the reactants, an insulating jacket, and the appropriate pipes and valves to control the reaction conditions. ... 

Catalyst lines between the reactor and the stripper had to be lined with Hastelloy B, and Hastelloy B valves had to be used. All nozzles in the reactor were similarly protected. Double extra-heavy 4-in. carbon-steel pipes were used in the reactor after cooler and replaced periodically. 

Example 2. In the previous example, the curvature of the levee and railroad track aroxmd the tank area determined the circular arc for the 680 psi, 650°F steam line. This 8-inch schedule 80 carbon steel pipe line will be redesigned and recalculated with the idea of using the smallest possible rise with the maximum bending stress Emax and the resultant force, F at the fixed anchor ends so they will be within the allowable stress range. A rise of 10 feet above the straight line 508 feet d distance will be tried first. (See Figure 7-51) The pipe will be suspended from fi ee movement pipe supports similar to the elevation shown in Figure 7-50.
