What kind of Sheet Lead Lining do you need to fight acid corrosion? / Oar Segnlar CHEMICAL IEAD? This is a practically pure lead, free from bismuth, to which has been added a small amount of copper to boost corrosionresistance and endurance limit. Used long and'successfully throughout industry for lining tanks and for covering apparatus exposed to corrosive fumes or acid splash, | it is the base lead fox acid handling. The other types, like Tellurium Lead or Antimonial Lead, are simply Chemical Lead-, alloyed with varying quantities of tellurium dr anti mony ti> impart extra qualities. Lead sheet is easily farmed into any shape and burned to give you onepiece, corrosion-resisting tank Unpigs, 2 Our Spaciaf TEU.URIUM LEAD? This is Chemical Lead contain-. ing a small amount of tellurium. You get all of lead's regular advantages plus certain new ones to meet special service conditions. One outstandingfeature ofTellu riumLead is itsincreasedcorrosion resistance at high temperatures. Another is its abiKty to workharden. Mechanical stress, such as bending, stretching or hammering, actually increcsesTelluriumLead's tensile strength and resistance to fracture. Tellurium Lead is especially recommended where you have to combat both stress and corrosion. Tellurium Lead stands up under vibration or fatigue stresses. That's why' it toes used here as a protective covering on rayon spinning machines.. 3 Our Extra-Strong ANTIM0N1AL lAD? This is made from either Chemical or Tellurium Lead by adding small amounts of antimony to secure greater tensile and mechanical strength. For example, lead containing 6% antimony has a tensile strength almost twice that of-Chemical Lead. This, plus its stiffness, makes it suitable for use where mechanical strain is severe or where linings are supported only by a skeleton framework. Autimonial Lead also is harder and more resistant to abrasion and cutting. It's a good bet wherever erosion or mechanical abuse exists. How ever, because antimony lowers the melting point, Antimonial Lead is not recommended for use above 240F. 6% Antimonicd Lead was used to line these precipitating tanks becauseithas the extra strength needed to withstand the vacuum used in the operation. .. v/.No Matter What Your Acid-Handling Problem...- National Lead is ready to consult with youand supply any type of lead pipe ... valves .. sheet... lead-lined or lead-covered equipment... even complete add recovery plants.
