Successful shipment for Aviation Kerosene Transportation Project

 In march, Xinyue received the order from the old customer in South Africa. ERW gr. BN PSL2 . In this spring and blooming April, after the production test for one month.The delivery was completed! And has passed the strict test of SGS in batches, all the physical and chemical tests were up to the standard!

It is a pipeline used for transporting aviation kerosene, the terminal has strict requirements on material quality, so it is necessary to issue the laboratory report certified by CNAS, and SGS is required to do the final inspection to witness the physical and chemical experiments.The experiment lasted 4 days .

The test data are very satisfactory . All four items from different heat Numbers are passed at one time.

The containers have been left China . we hope our customer can get good reputation from this project !

Xinyue is always returns customers with the best product quality and service, and strives for 100% customer satisfaction. Xinyue steel is your most reliable partner. Welcome to cooperate with you again!

Three welding processes

　　Three types of welding processes:

　　Electric Resistance Welding: During ERW, a high frequency electrical current is transmitted to the material by means of copper sliding contacts so that the abutting edges initiate fusion as they come into contact.

　　Longitudinal Submerged Arc Welding: In LSAW, the butt joint of the pipe is welded in at least two phases, one of which is on the inside of the pipe. The welds are made by heating with an electrode arc between the bare metal electrodes. Pressure is not used. Filler metal for the welds is obtained from the electrodes.

　　Spiral Submerged Arc Welding: Spiral SAW allows large diameter pipes to be produced from narrower plates or skelps. During this process, the weld pool is protected against oxidation by a flux produced from the electrode fed separately onto the weld.
