    Product Details

    Product Description

    FC full bore gate is a critical sealing component exclusively designed for API 6A standard oilfield gate valves. Adopting a slab-type full bore structure, it features a consistent flow passage with no diameter reduction, perfectly matching full bore valve cavities to enable unobstructed pipeline pigging and minimal fluid resistance.

    Forged integrally from high-strength alloy steel (AISI 4130/4140) or stainless steel, the gate boasts a compact, defect-free structure with exceptional mechanical strength and high pressure resistance (up to 20,000PSI). Its double-sided sealing surfaces are enhanced with HVOF thermal spray coating (WC-Co, Ni-based WC, Co-Cr-W alloy), delivering ultra-high hardness (HRC 75), superior wear resistance, erosion resistance and corrosion resistance.

    Processed by CNC precision machining, the sealing surfaces feature ultra-high flatness and finish, ensuring reliable two-way metal hard sealing without leakage under harsh working conditions. Compliant with API 6A temperature grades (K/L/P/U) and performance levels (PR1/PR2), it offers excellent interchangeability, long service life and strong adaptability to onshore/offshore oilfield wellheads, Christmas trees and high-pressure manifolds.

    Frequently Asked Questions

    Q1 What is an FC full bore gate and how does it differ from a standard gate?
    An FC full bore gate uses a slab-type full bore structure that maintains a consistent flow passage with no diameter reduction. Unlike standard gates, it perfectly matches full bore valve cavities, enabling unobstructed pipeline pigging and significantly reducing fluid resistance during operation.
    Q2 What materials are available for the FC full bore gate?
    The FC full bore gate is available in high-strength alloy steel (AISI 4130 / AISI 4140), stainless steel (316L), and duplex stainless steel (2205 and 2507 dual-phase steel), allowing selection based on specific media, pressure, and corrosion requirements.
    Q3 What HVOF coating options are available and what hardness can be achieved?
    Multiple HVOF thermal spray coatings are available, including WC/Co, WC/CoCr, Stellite 20#/NiCr, Cr₃C₂/NiCr, Ni60/Ni55, and WC/Ni. The coating can achieve an ultra-high surface hardness of up to HRC 75, with a bonding strength of ≥70MPa and porosity of less than 1%.
    Q4 What working pressure and temperature ranges does the FC full bore gate support?
    The FC full bore gate supports working pressures from 2,000 PSI (2K) up to 20,000 PSI (20K), and operates across a temperature range of -46°C to +121°C, compliant with API 6A temperature grades K, L, P, and U.
    Q5 What applications is the FC full bore gate suitable for?
    The FC full bore gate is designed for use in onshore and offshore oilfield wellheads, Christmas trees, and high-pressure manifolds. It handles a wide range of media including crude oil, natural gas, oilfield wastewater, mud, water, and oil-gas mixtures.
    Q6 What packaging and shipping methods are used for export orders?
    All export orders are packed using standard export packaging: an inner anti-rust protective bag and an outer fumigation-free plywood box or carton that is shockproof, damp-proof, and rust-resistant. Shipping is available via ocean freight or overland and rail freight to ensure safe delivery worldwide.
