Manufacturing torispherical heads 3200 mm Type C
When manufacturing Type C, the crown and knuckle are checked against the Type C diagram. Radii and profile height cannot be changed independently while retaining the same designation. Straight flange, bevel and allowances are specified for the joint.
For diameter 3200 mm, agree the blank, joint preparation and finished Type C profile inspection plan. Radii R = 2560 mm and r = 492,8 mm are recorded in the working drawing together with thickness and surface requirements.
- Mating diameter 3200 mm and ovality
- Profile R=2560 mm, r=492,8 mm
- Finished part thickness
- Straight flange profile and edge preparation
- Surface condition and documentation requirements
Applications of torispherical heads 3200 mm Type C
Check the requirements for the equipment receiving the head: Heads for industrial separators, Heads for flare separators (FS). These links describe the equipment applications; suitability of a specific head is confirmed by the equipment design.
Specify Type C separately from the diameter. Submit the equipment operating conditions, openings and additional loads for review of the selected profile.
Torispherical head 3200 mm Type C — GOST requirements
Type C uses its own crown and knuckle radius combination. It should not be described as a universal minimum-height option: dish depth follows the agreed profile and suitability follows the vessel calculation.
GOST 34347-2017 sets general manufacturing requirements for welded steel vessels; GOST 34233.2-2017 is used for calculations. The production range and profile radii are checked against the engineering documentation. For 3200 mm Type C, the catalogue specifies R = 2560 mm and r = 492,8 mm.
Weld inspection — Type C
For a welded blank, inspection methods and scope follow the technical requirements. Agree these for 3200 mm when ordering; one inspection package cannot be assumed for all materials, weld layouts and equipment categories.
For an order of 3200 mm Type C, state the drawing number and revision, material, thickness and acceptance requirements. Diameter 3200 mm does not replace the other specification requirements.

Frequently asked questions
What checks are performed before delivery?
Submit the project requirements for weld inspection methods, scope and reporting for the finished component.
Is Type C always shallower than A and B?
There is no general rule for ordering. Installed height is determined from the complete profile and straight flange in the specific drawing.
What information is needed for a quotation?
Provide the design pressure and temperature, medium, material, thickness, profile drawing and quantity. For 3200 mm Type C, also specify R = 2560 mm and r = 492,8 mm.
What is the lead time for torispherical head type c 3200 mm?
The lead time is confirmed after reviewing the material, thickness, batch size and processing requirements. The indicative lead time of 7 days or more is confirmed in the quotation.
Which material grades are available for torispherical head type c 3200 mm?
The grade is selected to suit the shell material, medium, temperature and welding process. Availability of a particular combination is confirmed after reviewing the project.
Delivery of torispherical heads 3200 mm Type C
The head of diameter 3200 mm Type C is delivered after packaging and transport arrangements are agreed. Vehicle selection takes into account the actual dimensions, component weight and batch quantity.
Include the delivery destination and unloading restrictions in the enquiry. Protection of prepared edges and surfaces is agreed for the project and transport conditions.
