Class 150 Flange

What pressure rating does a Class 150 flange have?

This rating denotes the maximum pressure a flange withstands at a specific temperature. As an established ASME B16.5 Class 150 weld neck flange supplier in UAE, we have high-quality products with a rating of 150 (dimensionless).

The pressure capacity goes down with increasing temperature. For example, a Cl150 flange tolerates 270 PSIG at ambient conditions but 75 PSIG at 800°F.

How does an ASME B16.5 Class 150 weld neck flange differ from other flange classes?

The appropriate class for industrial projects guarantees safety and performance. Class 150 long weld neck flange is available from 1/2 to 24”. B16.47 covers larger flanges (series A and B).

DIN standards usually have tighter tolerances than a Class 150 threaded flange.

Can a Class 150 slip on flange be used for both raised face and flat face applications?

Clients may employ various face types based on application conditions and budgets. A Class 150 flat face flange is simpler to install. It suits low-pressure applications.

In contrast, a raised Class 150 slip on flange is better for more critical roles.

What factors affect the cost of Class 150 forged flanges besides size and wall thickness?

Buyers should select these flanges per the environmental pressure and temperature (ambient and operating fluid). The costs of Class 150 forged flanges depend on the material grade and the sizing (non-standard may cost more). Additional treatments like polishing and sandblasting inflate prices of a 150# flange.

We can offer factory rates since we maintain a collection of non-standard sizes and have experts for integrated quality control. Note that higher pressure classes than a 150 lb flange increase the outside diameter, bolt circle diameter, and bolt hole number.

What are the advantages of using a Class 150 blind flange over other classes?

If materials like stainless steel are selected, these flanges deliver trustable performance and corrosion resistance. A Class 150 blind flange has a uniform distribution of bolt holes and a smooth surface finish. They are also easy to install and adapt to versatile sectors like petrochemicals and desalination.

What are the benefits of gaskets in 150 LB flange connections?

In a 150# socket weld flange, the core advantage of a gasket is a secure, leak-tight seal as compression changes.

A gasket minimises noise, vibration, etc., and prolongs the lifespan of a Class 150 weld neck flange.
