Description

· Обратный Клапаны are flow control devices that permit flow in one direction but stop flow in the opposite direction.
· Generally used in well service applications, the check valve is placed in the treating line to allow flow to the well but isolates any back flow upstream of the valve. This provides a safety device at various locations in the flow line and assures that pressure and fluid cannot backup into the manifold area or into the pumps, causing damage to equipment.
· The simplified Седло Крышка and seat assembly has a minimum number of parts.
· For the sealing at Низкого давления, All Тип Клапаны are consist of Stainless Стальной Springs.
· API 6A Materials Classes and Температура Classes are available.
· Стандарт service is used up to 15,000psi and tested at 22,500psi.
· H2S Обслуживание is used up to 10,000psi and tested at 15,000psi.
· Надёжный Performance at high working pressure.
· Клапан Parts are Взаимозаменяемый with most major designs.
· Suitable for variety of high pressure applications such as fracturing, cementing, acidizing and etc.
· MTR and Test Reports are available at any time.

Описание

Working principle-Обратный Клапан is used to prevent  pressure  liquid  from flowing backward.It lets the liquid flow just in one way

Function

Because  pneumatic  pumps  can  not  hold  pressure effectively,check  valves  are  installed  in  outlets  of  rough Насос  and  sub-Уровень  Насос.The  working  pressure  of  the 1″ stainless    steel Клапан can reach 200MPa(29000PSI),which can protect the  pumps  from damage.

Техническое обслуживание and trouble shooting

When  check  Клапан  can  notwork  in  good  condition,usually,it is wrong with Клапан seat or Клапан ball.Обратный and replace as follows:

1)Remote  the  Клапан   cap   and   get  Клапан   seat,and check whether they are in good condition,if it is damaged,it should be replaced.

2)Sometime,it  is  a  better  way  to  change  the  Клапан assembly because it is not needed to repair

 

Описание

Обратный Клапан is manufactured and tested in accordance with API Spec 6A, and often used in the oilfield when drilling, check Клапан is designed and manufactured in accordance with API 6A and API 16C standard. They are specifically made for mud, cement, fracturing and water Применение and are easy to operation and simple to maintain.We have many sizes and pressure ratings check valves used for drilling Применение.

Manufactured in sizes ranging from 2-1/16″ to 7-1/16″ and capable of withstanding pressures from 2,000psi to 20,000psi, these valves offer a comprehensive solution for a wide range of Применение within the oil and gas industry.

 

Description

CAMTOP Reclosable Circulating Sleeve Клапан | 10K PSI | DST Service

5 inch (127.5 mm)

Product Overview

The CAMTOP Reclosable Circulating Sleeve is assembled as part of the tubing string to establish communication between the tubing string and the casing annulus for single or multiple-tubing string completions.

The reclosable circulating sleeve is annulus pressure operated without the use of a wireline or coiled tubing tools. It features an internal sliding sleeve which seals against the circulating ports. The sleeve is held in place with shear pins; by applying a predetermined pressure to the annulus, the shear pins shear and the differential pressure shifts the sleeve to open the circulation ports.

A spring mechanism is equipped to close the circulating sleeve once the annulus pressure is released, using spring force to return the sleeve to the closed position. This allows multiple open-close cycles during a single trip.

CAMTOP Drill Pipe Float Клапан (DPFV) — Plunger & Flapper Series

Drill Pipe Float Valves (DPFV) are one-way check valves installed inside the drill string to prevent drilling fluid, cuttings, and formation back-flow from entering the drill pipe while making connections. CAMTOP DPFVs are manufactured as direct equivalents to Baker SPD Models F, FA, G, GA, GC, and GCA — covering both plunger type (F, FA) and flapper type full-flow (G, GA, GC, GCA) configurations. Each valve is forged from heat-treated alloy steel, precision-machined to API 7K / 6A / 8C and ISO tolerances, and individually pressure-tested before shipment.

Available in ten drill pipe sizes from 1R (1") through 6F (5-11/16") with matched metal and rubber repair kits, CAMTOP DPFVs are the reliable, cost-effective alternative to OEM drill pipe float valves for conventional and horizontal drilling operations worldwide.

Product Image

CAMTOP Drill Pipe Float Клапан (DPFV) — three Model F (Plunger Type) valves showing the standard H48013 / H48043 family design with spring-loaded plunger, alloy steel body and threaded drill pipe connection, equal to Baker SPD

The CAMTOP Model F plunger type drill pipe float valve is engineered for instant shut-off when making connections. The spring-loaded plunger design prevents flow-back into the drill string, keeping drill cuttings out of the bore and protecting downhole tools. Standard H48013 family (economy grade) and H48043 family (heavy-duty alloy grade) are both available.

Key Features

  • Six Model Series: F, FA, G, GA, GC, GCA covering both plunger and flapper designs
  • Baker SPD Compatible: Direct dimensional and functional equivalent — drop-in replacement
  • Heat-Treated Alloy Стальной: Кованый body with high tensile strength for deep well applications
  • Instant Shut-Off: Positive spring-loaded closure prevents back-flow during connections
  • Full-Bore Flapper Option: G/GA/GC/GCA models provide unrestricted bore for high-volume circulation
  • Carbide Orifice: GA/GCA models allow differential pressure readings at surface
  • Automatic Fill Feature: GC/GCA models prevent pressure surges during run-in
  • Complete Repair Kits: Both metal and rubber kits available for every size and model
  • API Certified: Manufactured to API 7K, 6A, 8C and ISO quality standards
  • 10 Drill Pipe Sizes: 1R through 6F (1" to 5-11/16") covering all common drill string sizes

Description

CAMTOP RD Rupture Disc Circulating Клапан | 5 Inch | 15K PSI | DST

5 inch (127.5 mm)

Product Overview

The CAMTOP RD Rupture Disc Circulating Клапан is the same as the RD Safety Circulating Клапан except it lacks the ball valve section. The annulus pressure causes the rupture disc to burst, and the pressure enters the rupture disc hole to push the circulating mandrel forward, opening the circulating ports.

The valve is composed of two major sections:

1. The power section consists of a power mandrel case and a rupture disc available for a wide range of pressure applications. The rupture disc bursts at a predetermined pressure, allowing annulus pressure to be applied to a differential area on the power mandrel. The power mandrel moves down, opening a set of circulating ports.

2. The circulating section consists of a set of ports initially sealed by the power mandrel. When the rupture disc bursts and the mandrel moves down, the ports are exposed, allowing communication between the annulus and the work string.
