performance feature
ASTMA53GR.B seamless steel pipe has high strength and toughness, capable of withstanding considerable pressure and tension, ensuring the safety and stability of the pipeline system. In addition, this material also has good wear resistance and impact resistance, which can effectively extend the service life of the pipeline.
strictly producing control system:
ASTM A53 GRB Seamless Steel Pipes have a large market share, as they can be frequently used in industries such as chemical engineering, power, and construction, providing reliable pipe materials for various fluid transportation systems. We are very serious to the whole production and inspection, every step will be performed as per the ITP.
1.Pre inspection before production for the raw material(steel billets).
Before Formed pipe : Assurance of compliance
Review of Sub-vendor ; quality plan ;
Review of samples certification (MTC)
Chemical analysis
Tension &Mechanical tests
2. Inspection for formed pipe
NDT operator qualification.
Eddy current testing.
Ultrasonic testing.
3.Ispection for the finished pipes.
MT testing for Edge of Pipe(If Exist)
Visual examination
Thickness measurement (Continous Ultrasonic)
Inside/Out Side/Length dimension control.
Straightness
Visual & Dimension check of edge
Weight control
Marking
4. Inspection for the delivery.
We will double check the pipe surface,such as no dust inside, no dents, marking, quantity,ect. In order to make sure it is 100% qualified to be delivered to our customers.
Protection coating
Certificate of compliance
Packing check(bundles, strips, caps, marking)
Shipping mark and number check.
