Impact Tests for High Alloys
Impact tests are not required for oil steel storage material nickel alloy welds made with electrodes/filler metals covered by AWS Specification A5.11 or AWS Specification A5.14, provided the nominal nickel content is 50% or greater, and the weld is deposited by the shielded metal-arc welding (SMAW), gas metal-arc welding (GMAW), gas tungsten-arc welding (GTAW), or plasma-arc welding (PAW) processes. When A5.11/A5.14 specifies the nickel content as a “remainder,” the nickel content shall be determined by summing the maximum specified values of the other elements (use the average specified value for elements with specified ranges) and subtracting from 100%.

After the API620 welded low-pressure storage tank inspection is manufactured, air tightness test and water filling test are carried out according to the design requirements, and the pipeline must be subjected to pressure test to fully meet the acceptance technical specifications. Improve the quality assurance system, adhere to the principle of who constructed is responsible for the quality of the project, conduct regular quality inspections, and immediately rectify any problems. Fill in the API620 welded low-pressure storage tank inspection installation technical records in time to ensure the synchronization, integrity and reliability of the technical data.

[Enterprise Spirit]: professional, honest, dedicated and innovative.[Enterprise Tenet]: provide customers with satisfactory steel products and services.[Enterprise Policy]: customer satisfaction is our pursuit. The trust of customers is our achievement.[Service Tenet]: to develop the market with quality and grow with sincerity.The company adheres to the commitment of quality first and customer foremost, takes high quality and high efficiency as the service principle, takes mutual benefit and common development as the business purpose.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API620 welded low-pressure storage tank inspection. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
