Professional Welding Clinic’s Post

Welding pipe fittings are the backbone of any robust piping system. They ensure seamless connections and durability in high-pressure environments. From industrial to residential projects, choose quality welding fittings for safety and reliability. 💪🔧 www.archpipe.com info@archpipe.com #WeldingFittings #PipeFittings #IndustrialPiping #Construction #Engineering #Durability #SafetyFirst

Steel Structure Fabrication Erection Installation

Erecting the Shell by the Jacking Method This method is gaining in popularity because it keeps the construction activities at a lower elevation and is therefore safer for the construction personnel. The foundation checks and the erection and welding of the floor is as traditional method but the shell is erected in a completely different way. Depending upon the overall height of the jacks being used, the top two, or maybe three shell courses are erected and welded in the conventional way and the roof struc- ture, sheeting and nozzles are completed. The tank designer should have calculated the number of jacks that are required giving due regard to the overall weight of the tank shell (excluding the bottom course) the roof structure, sheeting and fittings and also taking consideration of the effect of high wind loads on the tank. The jacks consist of a vertical post which has a specially designed hydraulic jack which climbs up the post carrying the weight of the tank with it. The tank is lifted in stages until it is high enough for another course of shell to be erected beneath the previous one, this can be between 1.5 to 2.5 metres. The jacking posts are fixed to the tank floor on a load spreading pad and secured in position by two raking struts set at 45° each side of the post, these also being fixed to the floor plating. As each course is erected, the vertical joints are welded followed by the horizontal joint between the adjacent courses. That all the work is carried out virtually at ground level and is therefore much safer for the construction personnel. #tank #storage #vessel #refinery #construction #welding #jacking #erection #tankerection #safety #safedesing #desing #engineering #API #terminal #plant #facilities #mechanical

API650 Tank Fabrication: Jacking method

jacking method tank erection

✔ Safety With up to 70% labour reduction possible using a steel solution compared to alternatives, fewer people equals a safer construction site. Prefabrication and dedicated lifting points on assemblies make for defined well-controlled erection processes. Steel decking and integrated edge protection facilitate safer working platforms. #steel #steelindustry #steelconstruction #steelfabrication #steelmaking #steelstructures #steelwork #steeldetailing #steelerection #construcción #siteengineering #siteengineer #sitework #sheetmetalfabrication #construction  #construction #project #steelstructures #fabrication #mega #megaprojects #inspection #inspector #steller #Owner #Contract  #Activity #Development

#WaterStopper: Water Stopper Joints welding by electric heater. Waterstop plays an important role in waterproofing a concrete structure, especially joints, the weakest part which is liable to leakage of water or chemical liquids. So waterstops are designed as a fluid-tight diaphragm embedded in or running along the joints to solve these problems. Joints formed between adjacent concrete pours and where mechanical elements penetrate the concrete are the most likely points of water ingress into below-grade concrete structures. To prevent this from occurring, waterstops are commonly specified and installed at every joint in the concrete below-grade.  #civilengineering #qaqc #qualityassurance #qualitycontrol #concrete #cement #concretetechnology #laboratory #labtest #construction #engineering  #expressway #KathmanduTeraiFastTrackRoadProject #materialstesting #concrete #laboratory #labtesting #tunnelconstruction #bridgeconstruction #roadconstruction

Key ASTM Standards for Stainless Square Hollow Section - ASTM A500: This specification covers cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. While primarily for carbon steel, it is often referenced for structural shapes, including stainless steel. - ASTM A554: This standard specifies the requirements for welded and seamless stainless steel mechanical tubing intended for use in mechanical applications. It includes dimensions and tolerances relevant to square and rectangular sections. - ASTM A276: This specification covers stainless steel bars and shapes, including flat bars, rounds, and square shapes. It provides chemical and mechanical properties for stainless steel grades commonly used in construction and manufacturing. - ASTM A312: This standard addresses the requirements for seamless and welded austenitic stainless steel pipes. While not specific to SHS, it may apply to related applications involving stainless steel in construction. - ASTM A789/A790: These standards cover the requirements for duplex and austenitic stainless steel pipes for general service. They can be relevant in applications that may use SHS in conjunction with piping systems. If you have any request, please contact:sales@union-steels.com
