What is a cylindrical shell?

A cylindrical shell is a rolled and welded cylindrical section used in pressure vessels, columns and industrial equipment. Shell rolling is selected based on diameter, thickness, material and required tolerances.

Which materials and standards can you support?

Typical materials include carbon steel, alloy steel, stainless and duplex depending on project specifications. Inspection and documents (MTC, dimensional checks, NDT as required) can be provided per ITP.

What information should I include in an RFQ?

Please include diameter, thickness, length, material specification, weld requirements, applicable code/standard, quantity, inspection scope and destination.

Contact / RFQ

Can you roll and fabricate large diameters?

Yes. We can review capacity based on diameter, thickness and material, and confirm lead time and inspection scope per your drawing and ITP.

Do you support NDT and documentation?

Yes. Typical options include UT/RT/MT/PT as required, plus MTC and dimensional records as agreed in the order.

Technical Highlights

	Fabrication scope: Cylindrical shells for pressure equipment and structural pipe are built from qualified plate, rolled to diameter, then joined by longitudinal and girth welds under procedures matched to your code (e.g. ASME VIII, project specs).
	Materials & standards: Carbon, alloy, and stainless grades are supplied per ASTM / API / KS-JIS listings in the table above; MTC, heat numbers, and replates follow your ITP and traceability rules.
	Welding & heat treatment: SAW / GMAW / FCAW and other qualified WPS can be applied; PWHT or stress relief is scheduled when thickness and code require it.
	Inspection & tests: Dimensional checks, NDT (UT/RT/PT/MT as specified), and hydrostatic or pneumatic tests are released with reports before shipment - send ID/OD, length, thickness, design pressure, and code for a feasibility review.
