Introduction to Needle Valve

Introduction to Needle Valve

A Needle Valve is a type of valve which can be used to regulate flow of a substance, usually either gas or water, through an appliance or system. The Needle Valve unique feature of the value is the inclusion of a small plunger, with a shape akin to a Needle Valve.

A Needle Valve is a valve which is used for regulating the flow of a fluid/gas through a system or an appliance. A small plunger is used in needle valve which looks quite like a needle.

This Valve is also known as an Isolation Valve or Isolation Needle Valve. Typically used to reduce high pressure to low pressure.

 

Advantages of Needle valve

  1. Using a Needle Valve helps in controlling the flow of the fluid to a very low rate with high accuracy.
  2. During installation you need not worry about the space, since Needle Valve is quite small and compact in design
  3. Even with a lesser volume of fluid, throttling is possible in this type of Valve
  4. The flow rate is Needle Valve can be adjusted very much precisely
  5. The operation, maintenance and use of Needle Valve is much easier.

Construction and Operation of Needle Valve

This Valve uses a pin (tapered) to open the space gradually which helps in fine control of the flow. The flow can be regulated and controlled using a handle which is connected to the spindle.

The orifice of a needle valve is relatively small when compared to other valves, the seat is long and tapered. The plunger exactly fits the seat.

When the handle is turned – which causes the plunger to retract the flow between the plunger and seat becomes possible. Until there is complete retraction of the plunger the flow of fluid is impeded.
This clearly means that in a needle valve the flow can be easily adjusted.

The plunger takes several turns to retract due to the fine threads a precise regulated flow rate is possible. 

Introduction to High Pressure Ball Valve

Difference between Socket Weld vs Buttweld

Difference between Socket Weld and Butt Weld

Pipe flanges, fittings, and valves can be connected in a variety of ways, including socket weld, butt weld, threaded, and so on. Socket welding and butt welding are two of the most common. However, you may be unsure which one is best for your infrastructure projects because they both appear to use their own set of advantages and disadvantages. As a result, we've taken on the task of making a comparison between them.

 

Socket Weld

They are made in line with ASME B16.11 standards. A pipe would be put into a recessed region of the fitting, or socketed to have a plain spigot end, in the construction of this type of connection. Socket Welding pipe fittings are utilized for combustible, hazardous, or expensive materials in which no leakage is allowed, as well as steam between 300 and 600 psi. SW pipe fittings are a type of high-pressure fitting that comes in multiple pressure rating systems: 3000, 6000, and 9000.

 

Butt Weld

They are made in line with ASME B16.9 standards. Each foot of the valve is sharpened to meet the depth and bevel of the pipe during the butt welding procedure. The two ends are then butted jointly and combined to the channel. The width would just be the same as for the pipes in this situation. Titanium pipes, duplex steels, and nickel-based alloys are all essentially butt welded.

 

Difference between Socket Weld and Butt Weld

  1. Welding grooves and seams of various types

Socket welding created a fillet weld during the welding process. Butt welding is superior to socket welding when considering factors such as weld strength, force conditions, and so on.

  1. Various applications

Because socket weld fittings are only half as strong as butt weld fittings. Socket welding is mostly used for piping with tiny diameters (Small Bore Piping), often piping with a nominal diameter of NPS 2 or less.

  1. Types of detection

In general, butt welding and testing standards are more stringent than socket welding and testing requirements.

To ensure that there are no leaks, the butt welding must be 100% tested, and radiographic inspection is required, but for socket welding, electromagnetic particle detection or infiltration detection is sufficient.

  1. Various costs

Socket weld fittings are more expensive than Butt welding fittings of comparable size. Butt welding fittings, on the other hand, require an additional expense because they are more difficult to manufacture and line up properly. This would take more time and would necessitate the use of qualified welders.

 

Conclusion

To summarise, socket welding has a higher pressure level and even a higher cost than butt welding. Butt welding is an alternative when welding technology is necessary and fully meets the construction standards. If the pipeline medium does not require welding, socket welding is advised since it is simple to detect.

Everything you need to know about single ferrule tube fittings

Everything you need to know about single ferrule tube fittings

Thermal cycling and vibration are known to be among the toughest environments for tube fittings. To ensure that the tube fitting does not fail under extreme conditions, these applications necessitate high-precision, leak-free technology. While there are a variety of tube fitting alternatives available, engineers need a solution that minimizes risks while also providing good value for money.

 

Techtube has created a single ferrule tube fitting design known as the compression tube fitting to meet this purpose. These tube fittings are suited for applications in process, power, and instrumentation. The fitting is simple to install and provides a strong anti-vibration hold on the tube with only three pieces required.

 

What is a single ferrule tube fitting?

The tubing is gripped by a single ferrule, which produces a leak-tight seal between the compression nut and the fitting body. In this situation, the single-ferrule serves two purposes at once: it seals the fitting while also locking it in place.

 

Benefits of single ferrule tube fittings

Here are some of the benefits of single ferrule tube fittings.

1. Less leak path

Single ferrule fittings have only two potential leak channels to seal, but double ferrule fittings have three or more potential leak paths to seal.

2. Less body contact

Single ferrule designs make less contact with the body, whereas double ferrule designs make contact with the body across the entire surface. In many applications, this permits the end-load to be concentrated in a smaller region, outperforming double ferrule.

3. Reduce vibration

The use of single ferrule designs creates a cushioning effect that reduces vibration.

4. Improved temperature cycling performance

Metals expand and contract in temperature cycling applications, causing dimensional changes in fitting connections. Single ferrule designs provide a "spring-loaded" action that keeps the fitting body and nut in continuous tension.

5. Installation ease

Single ferrule fittings necessitate the use of a coated nut, which reduces torque. The coating also extends the life of the fitting in service, reducing the need for maintenance.

6. Precision assembly

When there are fewer components, there are fewer things that can go wrong during assembly. Single ferrule fittings also take less time and effort to put together than double ferrule fittings.

 

Conclusion

To avoid leaks and associated damage while working with tube fittings for any piping-based application, a proper and trustworthy seal between the various components is required.

Single-ferrule or dual-ferrule compression fittings might utilize depending on the nature and purpose of the compression fitting application. Making the right decision will ensure that your plumbing system is protected from leaks and damage.
