ASTM grade pipes cover all the need of electric fusion welding (EFW) with the addition of filler material also for the low-temperature applications. These pipes are fabricated from the pressure vessel crude materials with various analysis and strength examinations. The class of pipes designates the heat treatment is performed.


ASTM A671 EFW Pipes are world class for its strength but also for corrosion resistance feature. These withstand a drastic environment without being failed. Importantly these pipes have good potential to work in harsh chemicals such as chlorides, alkalis, sulfides, and other acids. Often these serves good performance opposing the pitting and crevice corrosion cracking even in elevated temperatures.


Quality cross-check
These pipes are radiographically examined as to check the pressurized test. This pipe batch sample undergoes tension and transverse, guided weld test that conforms to the specified mechanical requirements. In order to get top-notch products more tests are performed that includes- hardness test, tensile test, positive material test, micro and macro test, chemical test/ spectro analysis, and intergranular corrosion test. Moreover, the final lot is inspected by third parties that state the quality of pipes.


Packaging and delivery option
Wooden boxes, crates, cases, cartons, and pallets are used as packing material for safe and secure transit. As per convenience customers can modify packing mode. The plastic film works as a shielding agent that resists oxidation.
