K / All-Lead Pipe? NationalLead's Chemical Lead Pipe has a long record of successful ap plications. And there are defi nite reasons for this. First, it is made of practically pure lead, which is free from bismuth and contains a small: amount of copper to increase corrosion resistance. Second, it Is fabri cated by an extrusion process which assures uniform wall thickness, free flow and free dom from porous or defective spots. Whateveryour problem, NUtiaiiol ' Lead has the lead pipeybit need' and a full line of fitting to- go with it. Here's a lead dis charge pipe used o settling tank. That's our regular lead pipe. It has become "standard" throughout industry. But, maybe you need extra corrosion resistance at high temperatures__ greater tensile strength and toughness . . . higher endurance to vibratory stress. Our Tellurium Lead Pipe fills the bill there. Or, maybe your extra problem is' erosion. Then, you should consider our Autimonial Lead Pipe, made with a base of either Chemical or Tellurium Lead. By adding 6%; of antimony we j almost double the; tensile strength ax|d greatly increase hardness and stiffness. 2 Cold Expanded Lead-Lined Pipe? When you need pipe with the .strength of iron or steel, we give it to you . . . with a lead .----- lining. Our "United" Lead-lined Cast Iron or Steel Pipe has proved highly serviceable { j . under severe conditions. It has the outer |t strength you need to stand pressure or. other I ;S mechanical stress; the inner stamina to resist corrosion. The lead lining is formed in continuous' lengths of seamless" pipe,, then cold ex panded against the inside of the iron or steel tube. You get a tight fit and a smooth, -- uniform lining, free of defects. Of course, all iron and steel pipe used meets ASTM standards. 5 The strength ofsteel plus the endurance of lead. You get both with **United" Lead-lined Pipe. 3' "United Tubond" Lead-Lined Pipe? For extremes of tempera ture, pressure, vacuum or vibration, investigate our "United Tubond" Lead-lined Pipe. This is steel or wrought, iron pipe with its.lead lining permanently bonded to the ferrous metal. No'separation or creep is possible. The illustration below proves the toughness of this bond. ' All our 'Iead-lined pipe is available in flanged, sections with the lead lining carried over the face of the recessed ..flange. .This/insures a positive lead-to-lead joint . at^each-flange,-'elim-` inating -any. danger of. leakage.'.- Permanentfy bonded1 Even Violent twisting of this sec tion of "Tubond" leadlined steel pipe couldn't break the bond.
