Stainless Steel S31703 Seamless Pipes have great formability, machinability, fabricability, weldability and wettability. Due to its fabricability pipes are easily modified into complex designs with traditional machines. However, with the machinability feature machining cost is decreased. This grade is only required standard machining feeds and speeds for a higher precise finish.
The SS 317L grade has higher weldability, it can be welded by all standard welding process such as TIG, MIG, resistance welding, submerged arc welding and more. Furthermore, this grade can be welded by with and without filler materials. These pipes are designed to lower to higher corrosion resistance in a wide range of processing streams. It is combined with resisting elements coupled with molybdenum content that assures higher resistance to corrosion. These pipes are highly alloyed in order to provide chloride stress corrosion cracking.
These pipes are highly resistive to stress corrosion cracking, crevice and pitting corrosion cracking. These pipes are basically made to perform in the environments having diluted sulfuric acids. Moreover, it offers higher resistance too many organic and inorganic compounds such as hot phosphoric acids. It has a good composition of alloying elements, provides exceptional resistance to general and uniform corrosion. It is one of the rare grade offer services in elevated temperatures.
To perform the production of SS 1.4438 Welded Pipes perfectly we recommend both hot and cold rolling operations. We also perform different heat treatment process such as quenching, annealing, and tempering on pipes to achieve desired mechanical attributes. When the hot working operation is performed, materials get desired mechanical attributes while preventing cracking and brittleness. This also removes the changes in the grain structure materials. When the manufacturing process is done, these pipes are processed from finishing operations to remove uneven surfaces, spill ends and roughness. In order to increase the live of pipes some coats are polished on pipes.
Quality at Piyush steel
The quality measures are followed by our professionals who are working dedicatedly to acquire the highest level of standard products. The superior quality of pipes is attained by performing quality assurance tests on the manufacturing facility. The quality assurance tests done on the stages such are material tests, destructive test and non-destructive tests.
• Positive material identifications (PMI)
• chemical composition analysis
• ultrasonic test
• pitting corrosion test
• micro and macro test
• intergranular corrosion test
• tensile test
• hardness test
• leakage testing
• thermal performance test
• Mechanical testing
• Compression test
• flaring test
Stainless Steel 317L Pipes are delivered and packed in the standard packing of wooden cases and form of bundles to protect any type of damages.
