Oil & gas manufacturing requirements.
Bolting for the full energy lifecycle.
Bolting for the full energy lifecycle.
Upstream, midstream, and downstream requirements bring demanding specifications, documentation, and delivery needs. Cyclone’s published API 20E and API 20F licenses and quality-management certificates give procurement teams a starting point for supplier review.
Identify the governing API, ASTM, and project specifications
State the required bolting specification level and material condition
Include sour-service, coating, testing, and marking requirements
Define the required material and inspection documentation
Products. Processes. Proof.
A practical path from your requirement to a manufacturing review.
Precision manufacturing
CNC turning, threading, cutting, marking, and inspection.
Upstream, midstream and downstream bolting
Connect your project specification to a complete manufacturing and supply review. Clear material, dimensional and acceptance requirements help the team define the quote and the records needed at delivery.
Part and procurement scope
Identify pressure-boundary or structural duty, the governing API and ASTM requirements, required bolting specification level, service conditions and project traceability. Sour-service or other additional requirements must be explicitly stated in the purchase specification.
Material grades and finishes
Published product listings include ASTM A193 B7 studs and stainless B8/B8M studs, with A194 2H, Grade 8 and Grade 8M nuts. Published B7 and 2H configurations include plain, TFE blue and cadmium-plated options. These references are not a recommendation for a particular service; supply the required grade, condition and finish.
Dimensions and availability
Stud bolts and stainless steel studs are offered in diameters from 1/2 inch through 4 inches, with lengths to the customer’s specification. Heavy hex nuts range from 5/8 inch through 4 inches nominal diameter. Consult the product range tables for grades and finishes. For custom parts, send the complete drawing; size feasibility, material availability and delivery are confirmed for the order.
Standards, inspection and documentation
API 20E and API 20F license scopes are available with the quality certificates. Review the original documents against your required product, material and bolting specification level.
Questions before you quote
What information speeds up an RFQ?
Identify pressure-boundary or structural duty, the governing API and ASTM requirements, required bolting specification level, service conditions and project traceability. Sour-service or other additional requirements must be explicitly stated in the purchase specification.
Are the listed grades approved for my application?
The customer or responsible engineer defines material suitability and the governing specification. Cyclone reviews the supplied manufacturing and documentation requirements; no universal application or customer-program approval is implied.
Can I combine standard hardware with drawing-specific work?
Yes. List each part separately with material, dimensions, quantity, finish and required documentation. The team reviews the complete scope and confirms the proposed delivery.
