It is used to transport crude oil, NGLs, natural gas and refined products for long distances across countries and continents. Transmission pipeline sizes are mostly greater than 25.4cm (10inch). Corrosion, defective welding, seam failure, and material failure are common causes of transmission pipeline damages.
A Practical Approach to Modeling Aluminum Weld efficiency and performance. One problem area for aluminum structures is the reduced strength of welded connectionsthe welding process involves local heating of the metal resulting in a local strength reduction in the weld and/or in the regi on immediately adjacent to the weld, referred to as the heat affected zone (HAZ).
ASTM A500 structural tubing is welded tubing made from flat-rolled steel, formed through a roller system and welded using electric-resistance welding. Longitudinal butt joints of welded tubing shall be welded across its thickness in such a manner as to assure the structural design strength of the tubing section.
ASTM International - Standards for Steel Pipes, Tubes and The ASTM International specifications for steel tubes list standard requirements for boiler and super heater tubes, general service tubes, steel tubes in refinery service, heat exchanger and condenser tubes, mechanical and structural tubing.. Steel Pipes. A53 - A53/A53M-99b - Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless

SSC issues report on crack arrestor enhanced aluminum Accordingly, ABS Consulting was tasked by the SSC to develop the following guide. The goal of this report is to enhance the existing modeling capability for crack initiation and propagation. This will efficiently and reliably capture the effect of a crack arrestor on the fatigue and fracture performance of a welded aluminum marine structure.
For everyone involved in any phase of welding steel structures---engineers, detailers, fabricators, erectors, inspectors, etc. - the new D1.1 spells out the requirements for design, procedures, qualifications, fabrication, inspection and repair of steel structures made of tubes, plate and structural shapes that are subject to either static or cyclic loading.
Structural Steel Welding - American Welding Societyweld metal leading to porosity. Weld joint cleanliness is also crucial in avoiding porosity since moisture, oil, paint, or rust on the base metal may also cause porosity by introducing oxygen or hydrogen into the weld metal. Employing some minimum preheat temperature is often useful to remove condensation.
