Spiral Steel Pipe

When Processing The Original Spiral Welded Pipe Of Spiral Steel Pipe, Weld Treatment Is The Essence Of The Original Spiral Welded Pipe. Welding Seam Processing Is Usually Divided Into Three Categories. Below, We Will Discuss The Welding Seams During The Processing:

The First Type Of Original Spiral Welded Pipe Weld:

All Welds In The Branch Pipe

Longitudinal Joint Of Steel Pipe Wall

Steel Pipe Circumferential Seam

Node Closure Loop Seam

Weld Seam Between Partition And Pipe Wall

If Ultrasonic Testing Is Used For This Type Of Weld, The Detection Rate Is 50%; The Radiographic Detection Rate Is 5%, And The Quality Requirement Is To Reach B1 Level Qualification.

The Second Type Of Original Spiral Welded Pipe Weld:

Steel Pipe Wall Joint

The Butt Weld Of The Thrust Ring And The Stiffening Ring, As Well As The Combined Weld With The Pipe Wall

If Ultrasonic Testing Is Used For This Type Of Weld, The Sampling Rate Is 50%, And The Quality Requirement Is To Reach B2 Level Qualification.

The Third Type Of Original Spiral Welded Pipe Weld:

The Welds Of Auxiliary Components Are Subjected To Less Force And Will Not Affect The Normal Operation Of Power Generation Or Water Injection Functions During Maintenance.
