![]() ![]() It provides a sacrificial anode (zinc) to receive corrosion instead of the steel corroding.It coats the surface like paint, and under most circumstances it forms a very adherent oxide layer like aluminum and SS.Galvanizing has two methods of corrosion reduction: Galvanized steel pipe is steel pipe that is dipped into a pool of zinc (see Figure 1). However, the high rigidity of steel means that although it expands less, it exerts very high forces on anchors. Consult ANSI/MSS SP-58: Pipe Hangers and Supports – Materials, Design, Manufacture, Selection, Application, and Installation for details about hangers and hanger spacing.Ī low coefficient of thermal expansion minimizes the need for expansion loops and expansion joints. More flexible materials, however, may require hangers on as close as 4-ft centers or even continuously. Steel pipe is manufactured in 21-ft lengths, and the hangers can be spaced that widely for large-diameter pipe. Rigidity is important because it determines the distance between hangers. Some building owners do not want these chemicals in steam that may be used for humidification because of health concerns however, not using these amines might require a change to stainless steel (SS) piping or adding a separate “clean steam” system for humidification and for sterilization of medical instruments. If amines (commonly cyclohexylamine, morpholine, or diethylethanolamine (DEAE) are fed properly to neutralize condensate pipe pH, condensate pipes can last the life of the building. 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 schedule 40 pipe. 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. ![]() Grade 316L stainless steel contains higher levels of carbon than 316 stainless, reducing its weld-ability.Steel often is used for closed hydronic systems because it is inexpensive, especially when compared with other materials in systems with high pressures, and corrosion is relatively easily controlled in these systems. The alloy contains higher percentages of molybdenum and nickel than Grade 304 stainless steel, increasing the corrosion resistance and making it an ideal material for applications in aggressive environments. Grade 316 / 316L stainless steel pipe is used for applications that require the high strength, toughness and work-ability, coupled with increased corrosion resistance. Standard welded pipe is in nominal lengths of 6.0 to 6.1 metres. With the exception of very large pipe welds are made without the addition of filler metal. Welded stainless steel pipe is manufactured from 2B or HRAP stainless steel strip - formed (to shape) and longitudinally welded to completed pipe. Stainless steel pipe and fittings are supplied in the annealed condition to facilitate fabrication and ensure best corrosion resistance. As a result of the aesthetic properties of stainless steel, pipe is often use in architectural applications. Stainless steel piping systems are the number one choice for carrying corrosive or sanitary fluids, slurries and gases, particularly where high pressures, high temperatures or corrosive environments are involved. Stattin Stainless stocks a comprehensive range of Grade 316 / 316L Schedule 10 and Schedule 40 Welded Pipe.
