Description
SA516 Gr70 plate is kept identifiable from cutting through final marking. SA516 Gr70 heads may be pressed, cold spun, or hot spun, depending on diameter, thickness, geometry, and plate condition. The forming route is followed by trimming, flange correction, and preparation of the circumferential weld edge. Openings, reinforcement pieces, direction marks, and surface preparation can be completed in the same production sequence. Material references remain attached to the part so the finished closure can be matched with its certificate. Dimensional results, material verification, and agreed non-destructive examination records can be included with the shipment.
Components
The crown establishes the selected vessel-end geometry.
Transition or knuckle sections connect the crown to the shell-side flange.
A straight flange or weld land supports alignment and circumferential welding.
Nozzle openings, reinforcement pads, lifting marks, and transport supports may be added to SA516 Gr70 heads.
Product Advantages
The material mark and heat reference can remain linked to the finished part.
Several forming routes allow the process to follow diameter, thickness, and geometry.
Beveling and opening work can be completed before the head reaches the vessel shop.
Documentation can be arranged by equipment number for projects containing several similar closures.
Why Choose Us
Material handling, forming, finishing, inspection, and packing are coordinated under one equipment tag. Four press capacities cover many sizes, while spinning lines support larger or less common dimensions. Heating furnaces and heavy cranes are available for thick and oversized work. The inspection area includes material analyzers, dimensional instruments, pressure-testing equipment, and non-destructive testing tools. This workflow helps keep the plate certificate, finished marking, inspection record, and shipping identification aligned.
Frequently Asked Questions (FAQ)
Q: Can heat-treatment requirements be included?
A: Yes. The required condition and supporting records should be stated in the purchase specification.
Q: Can third-party inspection be witnessed?
A: Yes. Hold points should be agreed before material cutting and forming begin.
Q: What information is needed for SA516 Gr70 heads?
A: Provide the shape, diameter basis, nominal and minimum thickness, flange height, openings, quantity, heat-treatment condition, and inspection scope.
