Dish end manufacturing l docs required

[ROCKEY SHARMA]

Dear Experts,

I recently installed a 300-ton hydraulic press for bending dish ends for vessels and storage tanks. Could you please advise on the necessary documents and certifications that our company may be required to provide? Specifically, I'm interested in knowing about WPS (Welding Procedure Specification) and PQR (Procedure Qualification Record) requirements.

Additionally, what technical data or questions can buyers typically ask for in this industry before placing any dish end orders?

Thank you for your guidance.

Best regards,

Rockey
