Weld test plates for thick-walled pressure vessels
Thread Content
I would like to ask fellow professionals: For a communication container with a wall thickness of 120 mm and a stress capacity of 35 MPa (with flat end caps on both ends), how should the welding test plates be selected? Is it necessary to conduct certain specific tests? Thank you!
What is a communication container? What is that Durex experiment? I’m ignorant and uninformed
I am very sorry; the correction is as follows. I would like to ask the experts: For a cylindrical vessel with a wall thickness of 120 mm and a stress capacity of 35 MPa (with flat end caps at both ends that are welded to the cylinder body), how should the welding test plates be selected? Is it required to conduct welding test plates for ring seams? Thank you!
The circumferential seam is determined in accordance with the requirements of the design documents; if no such requirements exist, it is not created
What is the diameter of this device? For those with a small diameter, forged cylinder shells are generally used; if there are no special requirements in the design documents, it is not necessary to create welded test pieces
Welding test plates with longitudinal seams are used; those without longitudinal seams may require test rings (depending on the design documents and the standards referenced therein).
It depends on the diameter of the equipment and whether there are Class A welds; this determines whether a welding test plate is needed. For plates of such thickness and under such high pressures, the cylinder body is usually made of forgings
