Description

1. Product Overview

The CAMTOP 13-5/8″ 5M psi Bolted-Крышка Сферический превентор (API 16A / 16D Class) is a large-bore, forged-alloy-steel pressure-control preventer engineered for deep onshore and offshore drilling on 13-3/8″ / 13-5/8″ casing strings. The bolted-cover design — studded upper housing + flanged lower housing — allows complete field rebuild of packing elements and seals without removing the ПВО from the wellhead.

Rated for 5,000 psi working pressure (7,500 psi hydrostatic body test), the unit qualifies under API Spec 16A and meets NACE MR0175 sour-service requirements. Replaceable wear bands on both the adapter ring and piston extend service intervals, while a dual-packer system (Nitrile Blue + Natural Red elastomers) supports a wide range of drilling fluids and temperatures. CAMTOP also offers a pre-packaged Уплотнение Комплект (P/N 155070) and an optional Гидроаккумулятор Комплект (P/N 152717) for fast rebuild and full hydraulic operation.

5. Component Breakdown & Construction

The CAMTOP 13-5/8″ 5M psi Bolted-Крышка Сферический превентор follows the standard bolted-cover architecture: a studded upper housing, a flanged lower housing, a spherical chamber containing the elastomer packer and piston, and a replaceable adapter ring. Below is the manufacturer exploded view (Figure 4-13) showing the 20 numbered internal positions used in the rebuild procedure.
