How to calculate the weight of pipe flanges?

1. Pipe flanges are used to connect pipe sections to other pipe sections, inline components, and equipment.
2. 1.The materials used to construct a pipe flanges directly relate to the weight and the pressure it can handle.
3. Pipe flanges volume=π/4*A1*A1－B1*B1－D1*C1*C1)*C(mm)

What is a figure 8 blind?

An ‘8 blind’ or a ‘spectacle blind’ is a piping fitting that is used for providing positive isolation. It consists of a pair of metal discs attached to each other as shown in the figure. They are also known as ‘line blanks’, since they are used to blank a line.

What is Spec blind?

Spectacle Blinds are simple safety devices that are installed between two pipe flanges. During normal operation, the open end is installed as a spacer to allow uninterrupted flow. This positively isolates the downstream piping and equipment. A Spectacle Blind is generally installed as a permanent fixture.

How do you measure a flange?

Measure across the base of your nipple, where your nipple meets the areola. Do not measure your areola, just the width of your nipple. Add 4mm to your measurement. These extra millimeters allow for a little space between your nipple and the flange tunnel, as well as for a bit of nipple expansion while pumping.

Paddle Blinds A Paddle Blind is basically the solid half of a Spectacle Blind. A Paddle Blind is often made from one solid metal disc and will usually have a thin length of metal attached to one end to be used as a handle. A finished assembly will resemble the shape of a paddle, hence the name.

What is blind flange?

A blind flange is a solid flange as shown below. The purpose of these is to block off a section of pipe or a nozzle on a vessel that is not used. Blind flanges, just like standard pipe flanges, can be raised face (RF) or flat faced (FF).

## What is the purpose of a spec blind?

Spectacle Blinds are generally applied to permanently separating pipesystems, or just to connect with each other. A Spectacle Blind is a steel plate cut into two discs of a certain thickness. The two discs are attached to each other by section of steel similar to the nose piece of a pair of glasses.

What is spectacle blind for?

A spectacle blind is a safety device used to isolate a section of line or piece of equipment when the line or equipment needs to be inspected or removed from service. It is different than a valve in that the blind is a permanent or long term isolation device.

How to calculate the weight of a blind fabric?

First, we would calculate the area of the blind: Area Conversion Formula: 10 square feet = 0.92 square meters. Weight Conversion Formula: 1 Kg = 1000 grams = 2.2 lbs. Fabric Area Calculation: 10′ x 18′ = 180 sq ft = 16.56 square meters.

### What are the dimensions of a spectacle blind?
