API 6A Wellhead Equipment Buying Guide

API 6A Wellhead Equipment Buying Guide

API 6A equipment is a high-value purchasing category. Before sending an RFQ, buyers should define pressure rating, nominal size, material class, PSL, PR, temperature class, connection type, and required documents.

Common Products

Casing heads, tubing heads, christmas trees, gate valves, flanges, adapters, crosses, chokes, and wellhead spare parts are common sourcing targets.

Documents To Request

Common documents include MTC, pressure-test report, dimensional inspection, packing list, traceability documents, and certification support where applicable.

Quote Comparison

Compare suppliers by technical compliance, document readiness, delivery time, packaging, export experience, and communication quality.

Verification before quotation

Use the article as an RFQ-preparation reference, not as a substitute for the governing project specification. Confirm the standard edition, equipment model, service conditions, dimensional interfaces, required certification scope and final manufacturer datasheet. For replacement parts, attach the nameplate, original part number and measured dimensions.

RFQ checklist

• Equipment name, model, part number and quantity
• Operating pressure or load, temperature and process media
• Dimensions, connections, materials and standard edition
• Drawings, photographs and existing nameplate information
• Required test reports, inspection records and traceability
• Destination, delivery date, packing and target price

Any numerical value cited from a public manufacturer page is an observed reference for that model only and must not be treated as a universal product specification.
