ASTM A182 Plug

What is a Plug

ASME B16.11 Threaded plug from plugs offer many advantages for product protection. These plugs can be inserted into threaded openings, providing a more stable and consistent seal and preventing dirt, moisture or other contaminants from affecting your threads

ASTM A182 plug is a tool or material for the temporary sealing of pipelines in sewerage and other liquid and gas transportation systems; typically for maintenance or non-pressurized line testing.

Plugs are essential devices used in the plumbing apparatus of both industrial and domestic water supply lines, machinery and so on. They are also for removal of air blocks on water pump lines.

Specification for ASTM A182 Plug

There are 3 types of threaded plug that hex head, round head and square head. Pipe plugs are used as end caps for fractional pipes in many industries. These pipe plugs are used by inserting them into the end pipe to block the flow.

Standard for ASME B16.11 Plug

ASME B16.11 is the standard for the forged steel fittings, including socket weld and threaded type. Material including carbon steel, alloy steel and stainless steel. Also described as Class 2000, 3000, 6000 threaded end fittings and Class 3000, 6000, and 9000 for socket weld end fittings

This standard contains pressure-temperature ratings, dimensions, tolerances, markings and material requirements for forged and threaded forged fittings. The relevant contents will be shown in below tables in this article.

A plug is a male threaded fitting which seals the end run of a pipe when fitted into a female threaded fitting. An end cap is a female threaded fitting and is threaded over the end of a piece of pipe to seal it off.

Classification of Thread Plug

There are three types of ASME/ANSI B16.11 threaded plug that hex head, round head and square head.Pipe plugs are used as end caps for fractional pipes in many industries. These pipe plugs are available in carbon steel & stainless steel and used by inserting them into the end of the pipe to block the flow.

Hex Head Plug

Hex plug is an important pipe fitting. Like a normal pipe plug, the hex pipe plug is threaded in the end and the cover or the top of the plug takes a hexagon shape. The hex pipe plugs are considered an easy and cost effective way to plug your pipe. The basic purpose is to stop the flow.

Round Head Plug

American threaded round head plug is used to plug into the pipe end by male threaded connection, so to block the pipeline and form liquid or gas tight seal.

Square Head Plug

A Square Pipe Plug has a male pipe thread on one end and a closed off square shaped plug at the other end. It differs from a Hex Plug only in that it has a square shape head instead of a Hexagon head.
