API 6A Weld Neck Flanges are pipe flanges attach by welding the pipes to the neck of the flanges. This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Welding neck flanges remove stress concentration and allow full working pressure and they are often used for high pressure applications. The inside diameter of the flange is designed to match the pipe's inside diameter. Weld neck pipe flanges are typically provided with a raised face, flat face, or RTJ facing.

Casing Cup Tester is mainly used for the pressure test on the casing string and blowout preventer stack. All of the oil (gas and water) well has been running in hole with casing and has been installing the mouth of wellhead equipment, to test pressure delamination one—off for casing and control blowout pressure system, also can be used to test pressure for casing at well site pipe yard. Test pressure very easy, provided the test pressure tool put in the casing.
