Description
1. Product Overview
The CAMTOP 7-1/16″ 5M psi Bolted-Крышка Сферический превентор is a forged alloy-steel wellhead pressure-control device engineered for 5,000-psi working pressure (PR1 service class) on onshore and offshore drilling rigs. Built to API 16A / 16D Class B with NACE MR0175 sour-service compliance, this compact 7-1/16″-bore (179.4 mm) spherical ПВО replaces the legacy 7-1/16″ 10M version for wells where 5M-class pressure ratings are sufficient — giving operators a lighter, lower-cost alternative without sacrificing safety. The bolted-cover design grants fast field access to internal wear bands and elastomer packers for fast rebuild and minimum downtime.
This page also includes CAMTOP’s complete 28-part BOM (Bills of Materials) plus the Figure 4-13 Bolted-Крышка Exploded View with all 20 component positions identified. Same spare-part rigor CAMTOP issues for its overhaul kits — giving purchasing, maintenance, and re-manufacturing teams a single-source P/N reference.

3. Key Features
- API 16A / 16D Class B, 5,000 psi WP / 10,000 psi Test — fully API-compliant pressure-control device for onshore and offshore service
- Кованый Alloy-Стальной Корпус (ASTM A4130 / A4140) — heat-treated, ultrasonic-tested, red epoxy-coated for corrosion resistance
- Bolted-Крышка Design — 16× B7 studs / 2H nuts permit rapid field access for wear-band and elastomer replacement
- Replaceable Wear Bands on Поршень, Нижний Корпус, and Переходник Кольцо — restore clearances without scrapping forged housings
- Dual Elastomer Packers (Nitrile Blue + Natural Red) — field-interchangeable elastomer options for hot, sour, or oil-base mud service
- NACE MR0175 Sour H₂S Compliance — qualified for HPHT and sour-service wells without special trim
- Compact 7-1/16″ (179.4 mm) Bore — seals 2-3/8″ to 5-1/2″ drill pipe and all standard wireline tools
- Пневматический / Гидравлический Operator Compatible — interfaces with standard accumulator closing units (CAMTOP / OEM)
- Full Spare-Part Coverage — 28 part numbers readily available from CAMTOP for fast rebuild and field overhaul
- Optional Уплотнение Комплект (P/N 155076) and Гидроаккумулятор Комплект (P/N 152715) available for turnkey rebuild support
