May 01,2017 SUG I tanks Inspection of Surfaces Exposed during Fabrication#0183;Storage tanks are used throughout the oil and gas industry for the bulk containment of fluids at different stages of the refinery process.Most often,products are stored for a short time before being transported for further processing.The American Petroleum Institutes API 650 standard outlines minimum requirements for the design,fabrication,erection,and inspection Keep readingOSHA Technical Manual (OTM) Section IV Chapter 5 Recent inspection programs for metallic pressure containment vessels and tanks have revealed cracking and damage in a considerable number of the vessels inspected.Safety and hazard evaluations of pressure vessels,as also presented in OSHA Instruction PUB 8-1.5,need to consider the consequences of a leakage or a rupture failure of a vessel.Inspection of the Hot Dipped Galvanizing Process KTA May 01,2020 SUG I tanks Inspection of Surfaces Exposed during Fabrication#0183;Inspection Steps In order for the galvanizing to perform as intended,it is important that each step of the process be monitored,and the final product be inspected.Inspection defined in ASTM A123,which would be reviewed in its entirety before inspecting the quality of galvanizing.The following is a summary of some of the inspections that should be performed by the galvanizers QC and

Dust on the surface can interfere with the coating's ability to bond to the surface.After blowing or vacuuming the surface,brush a clean white cloth across the surface (without touching the substrate with the hands as body oils or salts can be transferred easily to the surface and contaminate it).Cited by 3Publish Year 1997Author B.S.C.Rao,R.Madeswaran,R.ChandramohanDefects Introduced into Metals During Fabrication andthese can cause the material to fail during fabrication or enter service with defects present that may compromise integrity.Defects arising during service may result from the presence of defects or features introduced during processing and fabrication,the inadequate specification of materials,or operation outside the intended design criteria.1.CMP Services - PassivationCopper sulfate identifies the appearance of free iron which is conventionally induced onto the surface of a component during fabrication with steel components.The idea behind this process is based on an oxidation-reduction reaction which induces the dissolved copper ions to envelope or plate out over the free iron particles.
During the diffusion reaction in the kettle,the zinc-iron alloy layers grow perpendicular to all surfaces,ensuring edges,corners,and threads have coating equal to or greater than flat surfaces.Additionally because hot-dip galvanizing is a total immersion process,all interior surfaces of hollow structures and difficult to access recess of Article Iron contamination and rust staining on stainless Avoid contamination during all storage,handling and fabrication stages and also during the service life of the stainless steel item.If contamination is suspected then test the surface.Where contamination is detected take steps to remove it all and avoid spreading it around during the removal operation.Avoiding 'iron' contaminationArchitecturally Exposed Steel - AISC Homefabrication heading below.4.Mockup will have finished surface (including surface preparation and paint system).5.Obtain Architects approval of mockups before starting fabrication of final units.6.Retain and maintain mockups during con-struction in an undisturbed condition as a standard for judging the completed work.a.
