Conventional Wellheads Systems

Camero1n Conventional Wellhead Systems provide the flexibility, compatibility and interchangeability required for a wide rangeof surface applications. With the proven features of Cameron systems comes reduced inventory requirements, lower costs and the ability to provide standard components. Cameron provides two Conventional Wellhead Systems, the S Wellhead and IC Wellhead. The Cameron S Conventional Wellhead System offers the industry’s highest capacity conventional spool-type wellhead and is designed for use with all well depths and types of completions. The IC Wellhead is a costeffective, reliable system for a variety of applications. Although components are not interchangeable, the S Wellhead may be used in place of the IC Wellhead for all applications. In addition, both wellheads are compatible with most Cameron tubing spool and hanger configurations. Cameron has earned a reputation for quality wellhead products that meet or exceed API 6A specifications. Cameron offers a complete line of conventional wellheads and Christmas trees to suit all casing and tubing programs for working pressures up to 30,000 psi. Equipment for surface applications ranges from low pressure, conventional equipment to systems for severe service and geothermal applications. For equipment requirements not covered in this brochure, contact your Cameron representative.

 

Selecting a Wellhead System

The first step in determining which Cameron wellhead system is best for your application is to determine the casing hanger style to be used. Each hanger profile is unique and is generally compatible with only a limited number of casing head/spool bowls. Cameron has a complete line of slip-type casing hangers divided into two segments, SB and IC, each serving different applications.

A Family of Quality Gate Valves from the Industry Leader

During the past 60 years, numerous gate valve designs have been used in the oilfield. Slab gates, parallel gates, and expanding gates are a few of the designs that have been utilized in valves to control the flow of fluids in Christmas trees, flow lines, pipelines and processing plants. Cameron engineers have carefully studied existing valve designs, their features, benefits and applications. The result is a collection of preferred gate valve designs representing the Òbest of the bestÓ in gate valve technology today.The new Cameron gate valve product line offers:
-Valves for applications from 2000 to 20,000 psi WP.
-Large and small bore valves.
-Valves fitting a wide range of land, offshore and subsea applications.
-Cast and forged bodies.
-Expanding and slab gate designs.
-Components constructed of various alloys for severe service applications.
-Designs suitable for actuation and compatible with a wide range of actuators.Cameron’s more than one-half century of experience designing, testing, installing and refurbishing gate valves has established a worldwide reputation for manufacturing excellence. Every valve must meet the exacting standards mandated by its end use. To ensure these standards are achieved, Cameron uses state of-the-art materials and machinery in its manufacturing process. Thus, it is not surprising that Cameron’s reputation carries over to customer service, a dedication to quality assurance, intensive service personal training programs, and Cameron’s highly regarded network of aftermarket facilities. It is this attention to total quality and excellence that enables Cameron to consistently deliver the world’s finest gate valves to fill its customer’s needs.

The Cameron FL Gate Valve has earned a reputa-
tion in all types of applications. The FL
is a full-bore, through-conduit valve
available in standard double flange,
threaded-end and special block body
configurations. It is a forged valve which is
available in 2000, 3000 and 5000 psi WP and in bore sizes from
2-1/16″ to 4-1/16″ and can be fitted with a wide range of
Cameron actuators.

-Bi-directional design provides flow direction versatility and
increased service life.
-Positive metal-to-metal sealing (gate-to-seat and seat-to-body).
-Simple, reliable gate and seat design promotes ease of field
service and minimal spare parts inventory.
-Spring-loaded, pressure energized, non-elastomeric lip-seal
between each seat and body assists in low pressure sealing.
It also protects against intrusion of particle
contaminants into the body cavity and seal areas.
-Stem seal design covers full range of pressures,
temperatures, and fluids encountered in
wellhead and manifold service.
-Metal-to-metal bonnet seal.
-Stem can be backseated to allow stem seal
replacement with valve under pressure.
-Grease injection fitting located downstream of
stem backseat for safety. Fitting located in bonnet,
eliminating body penetration.
-Bearing cap grease fitting allows positive bearing
lubrication.
-Easy closing and sealing without excessive force.

 

 

 

 

FLS-R Gate Valves

The Cameron FLS-R Gate Valve wasdesigned for use as a manual valve in high-pressure, large bore applications. This valve incorporates a lower balancing stem and unique ball screw mechanism for ease of operation in the field. The FLS-R is value engineered for reliability, low torque, ease of operation and service. The FLS-R has many of the same features as the FLS including the gate and seat design.
Features and Benefits
-Bi-directional design provides flow direction versatility and increased service life.
-Positive metal-to-metal sealing (gate-to-seat and seat-to body).
-Simple, reliable gate and seat design promotes ease of field service and minimal spare parts inventory.
-Two spring-loaded, pressure energized, non-elastomeric lip seals between each seat and body assist in low pressure sealing. They also protect against intrusion of particle contaminants into the body cavity and seal areas.
-Lower stem balances pressure thrust on upper stem to reduce operating torque, prevents body cavity pressure build-up during operation, and provides position indication.
-Spring-loaded, pressure energized, non-elastomeric stem seal covers full range of pressures, temperatures, and fluids.
-Pressure-energized metal-to-metal bonnet seal.
-Either stem can be backseated to allow stem seal replacement with valve under pressure.
-Grease injection fittings located on the downstream side of the stem and the balancing stem backseat for safety.
