ASME B16.5 Bleed Ring

What are Bleed Rings(Drip Rings)?

Bleed Ring or Drip Ring is a type of flange that has one or more pipe connections arranged in a radial manner inside circular bolts and fits smoothly between flanges of standard sizes. Bleed Rings are used in hydraulic equipment. They are spacers that facilitate fluid flow. Some of them are bolted to the machine, while others are clamped. They are available in 4 main types and are typically 38mm thick. Each Bleed Ring or Drip Rings is stamped with its size, heat number, and rating. Bleed rings are a unique component of piping systems. They are available in a wide range of sizes and can match any type of flange. Bleed Rings are also called drip rings, vent rings, test inserts, and bleeder rings. These rings are used to match any type of flange and are available in different sizes, depending on the ASME flange rating.

Bleed rings can be made of stainless steel or other corrosion-resistant materials. The stainless steel type is typically used in the oil and gas industry. This material is corrosion-resistant and can be matched with a variety of flanges. They can slow down or shut off pressure. They can also be used to replace a leaky valve. They are usually manufactured in 1/2 or 3/4-inch sizes. The choice of tap size can affect the overall thickness of the ring. Bleed rings are often used instead of DIN Flanges because they are easier to install and more economical. They are particularly useful in brownfield operations. They also give easy access to drain piping, making them ideal for sample taking and instrument attachment.

Bleed Rings can be used in low-pressure applications, as well as for high-pressure systems. They come in different flange dimensions, which vary depending on the standard used. SS Bleed Rings are generally made of low alloys and are suitable for low-pressure systems, while Alloy Steel Bleed Rings are used for high-pressure systems. Neo Impex Stainless Pvt. Ltd. (NISPL) is a manufacturer, supplier, and exporter of the best quality Bleed Ring. Our Carbon Steel Bleed Rings provide a convenient mode to drain pipes and attach instruments and devices because their faces can be matched to a variety of flanges. Our Stainless Steel Bleed Rings are corrosion-resistant and are mounted between two valves, acting as pressure-releasing rings.

What is a Bleed Ring?

ASME B16.5 Bleed Ring is a type of flange that is used to vent trapped pressure or vacuum in a piping system & typically consists of a ring with a small hole or a series of holes that allow for the release of trapped pressure or vacuum from the system. They are commonly used in high-pressure and high-temperature applications such as power plants, oil and gas refineries, and chemical plants to ensure safety and prevent damage to the equipment.

What is the difference between a drip ring and a bleed ring?

A Drip Ring and a Bleed Ring are both types of flanges, but they have different functions:
A Drip ring is a type of flange that is used to prevent condensation or dripping from a pipe or other equipment. It is typically installed at the bottom of a pipe or equipment to collect any condensation or dripping and redirect it to a drainage system. A Bleed Ring, on the other hand, is a type of flange that is used to vent trapped pressure or vacuum in a piping system.

What is the purpose of a bleed ring?

A Bleed Ring is a component in a fluid system that allows air or gas to escape from the system, typically to prevent the buildup of pressure. It is usually placed in the highest point of a fluid circuit and is used to allow air to escape from the system. This helps to maintain the correct fluid level and prevent the system from malfunctioning.
