Purpose of Orifice Fitting

 


One of the most popular methods for measuring natural gas is the dual-chamber Daniel Senior Orifice Fitting. It is the most widely used device for measuring natural gas, with well over a million installed bases globally.

The Senior Orifice Fitting offers a quick, secure, and easy way for users to replace orifice plates, saving them time and money. Daniel Ultrasonic Flow Meter creates under pressure without disrupting the flow. Because of the dual-chamber design, there is no longer a need for expensive plumbing bypasses like the extra valves and fittings needed for installations using typical orifice flanges.

Key Elements

Units for Plate Sealing

It can be utilised for a number of purposes and offers a reliable seal between the body seat and orifice plate.

Plate-Carrier

Protects the orifice plate during installation and removal, and it is simple to insert when the fitting is mounted horizontally.

Projection Plate

It makes the location of the sliding valve inside the fitting more evident.

Operation

Senior Fittings 2—to 12-inch and smaller line-size fittings can be installed in a horizontal flow configuration for side openings or can function in a vertical downflow condition.

Customary Uses

  • Pipelines
  • Distribution of gas
  • Production of gas, both onshore and offshore
  • Gas-processing plants
  • Production, storage, and offloading via floating (FPSO)
  • Injection of CO2

Vital Information Regarding Daniel Fittings

·       The orifice plate carrier uses metal-to-metal orifice plate alignment in 8-in line size fittings and smaller to assure compliance with the stringent eccentricity criteria of the API 14.3 and ISO 5167 standards.

 ·       High differential pressure plate changes are made possible by the plate carrier.

 ·       There is no field adjustment available for the plate alignment and orifice plate carrier for 2- to 8-inch fittings. This guarantees that the fitting stays in factory specs.

 ·       To satisfy API 14.3 and ISO 5167 criteria for seat gaps, a single seal ring may be utilised for all pipe schedules in a particular line size (up to Schedule 30 or Standard, whichever is bigger). (This lessens the requirement to buy several seal rings.)

 ·       Field-repairable, which minimises downtime and transportation expenses to a repair location.

 ·       All Daniel Senior Orifice Fitting undergo hydrostatic testing when working with clean gas products, such as ethylene.

Everything You Should Know About Turbine Flow Meter

Image
Daniel Turbine Meter is used for volumetric total flow and flow rate measurement. The mechanism has a relatively simple working principle. Since fluid flows through the turbine meter – it affects the turbine blades that are free to rate about an axis along the center line of the housing. Liquid turbine serves a variety of hydrocarbon application including fiscal and custody transfer, check metering or blending. Well, the flow meters are installed for measurement during crude oil production, storage inventory control, floating production, offloading also refined product loading and offloading. The repeatability of the meter ensures quality measurement over a wide range of flow rates, temperature, composition, and viscosities. It is the largest combination of line sizes, pressure and materials as standard turbine meter configuration with the most international product approval. Daniel PT Turbine Meter It is widely preferred for their low-cost installation, maintenance ownership. D...

Accurate Liquid Turbine Flow Meters for Oil and Gas Applications

Image
Chemical blending, custody transfer, and petroleum processing are just a few of the applications where precise liquid flow measurement is essential. To guarantee accurate and trustworthy measurements, high-accuracy liquid turbine flow meters are needed. Since it is so accurate and dependable, the liquid turbine meter has become very popular. This blog will go into greater detail about the Daniel 1500 Turbine meter . Knowing How Turbine Meters Work The purpose of a turbine meter is to gauge the volumetric flow rate of liquids moving through a pipeline. The force of the flowing liquid rotates a turbine rotor that is placed inside the flow stream. The electrical pickoffs on the meter body then transform the rotating speed of the liquid as it passes through the turbine meter into electrical signals. Accurate measurement is possible because the electrical frequency output is proportionate to the flow rate, with each pulse denoting a tiny incremental volume of flow. Turbine Meter C...

How Can Excel Loading System Help You

Image
Excel Loading Systems may assist in the safe and effective transportation of gases and liquids, especially bulk goods, from totes, railcars, and vehicles. These systems include advantages such as quicker loading and unloading times, enhanced efficiency, decreased environmental impact, and higher safety. HERE'S A CLOSER LOOK AT THE WAYS EXCEL LOADING SYSTEMS MIGHT BE BENEFICIAL: Enhanced Security Loading Arms at the Bottom - Minimizes the chance of falls and injuries by enabling operators to stay on the ground. Loading a Closed System - Reduces the chance of coming into contact with dangerous substances by minimizing vapor discharges. Loading Arms that are Properly Built and Maintained - Minimize the impact on the environment by lowering the possibility of spills and leaks during transport. Enhanced Productivity In order to increase throughput, loading arms enable the loading of numerous compartments in a truck or train at the same time. Reduced downtime and increased operationa...
