How Does Stainless Passivation Work?For manufacturers,the industry standards ASTM A967 and AMS 2700 represent the most widely used standards for passivating stainless steel.According to ASTM A967,passivation is the chemical treatment of stainless steel with a mild oxidant,such as a nitric acid solution,for the purpose of the removal of free iron or other foreign matter.

Welded Steel Structures - an overview ScienceDirect Topics

An existing welded steel structure was designed for a pipe reaction load F y = 250 lb (Figure 5.18(a)).The existing valve near the support was replaced by a new,heavier valve,which brought the total load on the support up to F = 424 lb.Engineering is asked whether the existing support can take the new increased load.In this example,there is no lateral pipe load on the support,only the Water Tank Guide - Caldwell TanksComposite Elevated Storage Tank (CET) An elevated welded carbon-steel water storage tank supported by a large diameter steel-reinforced concrete support tower that extends vertically from the steel-reinforced concrete foundation as a circular concrete support structure/wall and has special horizontal and vertical rustication patterns formed into the exterior of the tower.Technical Inquiries for API Standard 650,Welded Tankswelded pipe meeting API 5L,for nozzles in shells made from Group IV,IVA,V,or VI materials,but allow use of electric-fusion-welded pipe nozzles made from ASTM A 671? 1 Yes,unless ASTM A 671 pipe is used.2 Yes.Technical Inquiries for API Standard 650,Welded Tanks for Oil Storage
