Differences between forged bull plug and tapped bull plug

A forged bull plug is produced as metal is forged at elevated temperatures. Here heat billets are passed through shaping them into different sizes. The bull plug with tap is produced as metal is pre-punched or extruded through a hole. This helps create threads for engagement with another device. A tapped tool is used in metric and imperial sizes to produce a tap bull plug.

Is NPT the same as NPS?

An NPT threaded bull plug is designed with tapered threads which are 2 inches apart from each other. These plugs can meet each other during the connection. The NPS threads are parallel to each other and are straight.

Difference between SCH 40, STD, S160, XH, XXH Bull Plug

Schedules help define the wall thickness of a bull plug. An SCH 40 bull plug is designed to handle lower pressure and temperatures. The XH bull plug is manufactured with the same wall thickness as schedule 80. These plugs can handle moderate pressures and temperatures. An STD 160 bull plug can handle considerably higher pressures and temperatures. The XXH bull plug is a heavy duty plug that has enhanced strength and tolerance to elevated temperatures.

What Is A Bull Plug?

A bull plug is a solid plug that is used as an isolation device in the piping system. Conduits and wellbore tubulars are used alongside a coupling to seal the piping area. The bull plug pipe fitting helps in characterizing the flow of gaseous and liquid flow in the system. These fittings are available in lengths between 6 to 18. The hex head bull plug has a hexagonal cross section. These plugs have a unique design that allow them to move easily in the system. The hex bull plug can be custom designed in different sizes and dimensions.

The plugs are designed commonly with carbon and stainless steel. A carbon steel bull plug has a higher content of carbon that gives it moderate strength and corrosion resistance properties. A stainless steel bull plug has excellent corrosion resistance properties and works well across harsh environments. These plugs are divided into 304 and 316 grades. The ASTM A182 f304 bull plug is designed with a chemical composition of 18% chromium and 8% nickel alongside other alloys. The ASTM A182 f316 bull plug has a chemical content of 16% chromium, 10% nickel, and 2% molybdenum content. This gives the 316 pipe bull plug enhanced corrosion resistance properties over the 304 grade. However, the price of 304 grade ASTM A105 bull plug is cheaper than 316 grade.
