High Pressure Pipe Fitting Manufacturers in India

The high pressure fittings mostly use a coned and threaded connection. It helps in accommodating high temperatures and pressures which are quite common in these applications. Clients can get high pressure valves in customized tubing sizes according to their specific requirements. These high pressure fittings are used across many industries and it can satisfy a wide range of requirements. The high pressure fittings should be marked with material specifications and they should have weep holes for added safety. These fittings are suitable for both liquids and gases, and they are made using high quality stainless steel. They also show excellent capacity performances.

What is High Test Wrought Welded Fittings?

The specification for high test wrought welded fittings is basically covered by the factory-made, electrical welded, and seamless carbon and low alloy steel. The butt-welded fittings are primarily used for applications that involve the use of high pressure, for example, in the transmission of gas and oil. These are also widely used in the distribution system of pipelines, metering, compressor and regular stations.
It is a very standard practice which determines the ratings, tolerances, along with the testing materials, along with their chemical and mechanical properties. The notch toughness properties are also considered for manufacturing and marking the high-test butt-welding fittings.

Difference between 6000 psi fittings and 12000 psi fittings?

High pressure fittings are one of the most important components of the hydraulic fluid system. Also known as the connectors or adapters, they are the standard connecting points between two pipes, tubes, hoses, and other piping components. It is essential that the connectors are able to handle the high pressure without leaking so that there is no disruption in the operation.
The main difference between 6000 psi fittings and 12000 psi fittings is in its capability to handle pressure. The 6000 psi fittings are able to handle lesser pressure when compared to the 12000 psi one, but we cannot call them low pressure or high pressure fittings as the term is very relative.

Forged steel fittings for high pressure application?

The forged steel fittings are used for connecting different equipment so as to create a piping system. These are available in 2 to 4 inches diameter and these are present in various forms too. The forges steel fittings are used in a wide range of industries for several high pressure applications especially where the threaded connections are intricate. For example, these fittings are widely used in instrumentation, heat exchanger, chemical fertilizer, refineries, nuclear thermal plants and various other industries. It is ideal for use in high temperature applications and generally used for transporting high-pressure liquids and gases from one place to the other.

What is PSI 9000 fittings and flanges?

The 9000 PSI fittings and flanges are primarily used for several hydraulic applications. These are basically welding flanges which are made of the carbon steel material and they usually have a rounded structure. They are usually manufactured through the forging process. These are usually zinc plated, and available in all sizes. These fittings and forges can easily be customized according to the requirements specified by the clients. These flanges are made of the carbons steel material and hence are very durable. They can last for a lifetime with low maintenance. It is an affordable choice for high pressure applications across several industries.

Which fitting is suitable for high-pressure piping?

Stainless steel grades like 304L, 316 and Inconel are ideally used for high-pressure fittings for the piping system. These are strong fittings that can withstand high pressure and are capable of holding the pipe. At the same time, it should be able to retain its original mechanical properties that the materials of the piping system possess. These pipes are available in various pressure ratings and the fittings also have to match that. The performance also depends on the grade of the material. For example the 304L stainless steel is affordable but it possesses less corrosion resistance and oxidation resistance properties when compared to the other higher grades.

What’s the Difference Between Low, Medium and high pressure pipe fittings?

Low pressure fittings are basically used for building connections of systems that involve low pressure. These are generally capable of withstanding working pressure that goes up to 250 PSI. They come with the biggest bore size of the three. The medium pressure connector comes with a comparatively large bore size and they are capable of accommodating pressure of up to 20000 PSI at 10 degrees F. The high pressure fittings however, comes with a significantly smaller bore size and it can withstand working pressure of up to 60000 PSI. The additional material present inside this pipe fitting helps in increasing its strength.



Why are high pressure Forged Components stronger?

High pressure forged components always show more desirable physical characteristics. This includes a very high degree of tensile strength, which is one of the main highlights of forged products. This property is mainly acquired due to the change in the metal’s grain. When the metal is forged, it never gets melted. In fact, it is given a percussive and compressive force during the forging process, which forces the grain in following the flow of the ultimate finished product. It helps in creating a stronger component which is much higher in strength when compared to its machined or the casted counterparts.

Problems of Corrosion in high pressure forged steel fittings?

There are several problems of corrosion in high pressure forged steel fittings, like:

  • Dead end condenser water lines- Microorganism, dirt, and other particles along with fully oxygenated water can increase the corrosion level dramatically.
  • Dual temperature services- The dual temperature piping system acquires corrosion slowly and it only gets discovered when the pipe is almost damaged.
  • Fire sprinkler inlet lines- These mostly acquired localized corrosion which is not a major vulnerability for the entire fire protection system.
  • Condenser water by-pass configuration- The open ones are most vulnerable to corrosion with the dead ends being the point of potential long-term threat.

How much pressure can steel fittings hold?

The amount of pressure that a pipe and pipe fitting can hold depends on its size, and schedule number. The general formula for calculating allowable pressure is:

calculating allowable pressure

Where, P= allowable pressure expressed in lb per square inches
D= Outside diameter expressed in inches
t= the design thickness expressed in inches
C= allowance in inches allotted for corrosion along with mechanical strength (the standard calculation is C= 0.05” for all the different pipe sizes)
y= coefficient of ferritic steel, which are as follows:
The value is 0.4 up to and including the temperature of 900 degrees F.
The value is 0.5 for the temperature of 950 degrees F
The value is 0.7 for and above the temperature of 1000 degrees F

What are BS 3799 Forged Fittings?

High pressure forged steel fittings

The BS 3799 is a specification for steel pipe fitting, which in forged form are used across several industries. The forged threaded fittings of the given standard are primarily used in pipes with small diameters and low pressure applications. Threaded is one of the oldest methods of connecting pipes; it is reliable and durable too.

The threaded fittings are quite affordable and they are mostly found in less critical applications.These fittings are mostly found in domestic piping systems. They are made with different materials like carbon steel, alloy steel, and stainless steel. The degree of the threaded fitting determines the directional change of the flow.

Two of the most common specifications when it comes to high-pressure fittings are ISO and NPT threads. Even though they might appear similar, they are indeed fully different when it comes to applications involving high-pressure environments. The ISO threads might appear similar to the NPT threads in terms of size and dimensions but they possess different pitch, which is the distance between the threads. The fittings compatible with ISO threads are mostly found on equipment manufactured across the world, whereas the NPT thread compatible equipment are manufactured from North America. Thus, it is essential to determine which thread the given equipment is compatible with.
