The ESS-ELL Model "ER" Landing Nipple is a Bottom No-Go Landing Nipple that allows for the location of many Flow Control Devices, such as Blanking Plugs, Bottom Hole Chokes, etc.
The "ER" has a locking groove which serves to allow for the internal locking of the flow control devices. The honed seal area provides a polished seal surface to pack off any flow control device. The Bottom No-Go shoulder provides the means to positively locate the appropriate flow control device into the "ER”.
There are a wide range of materials from which the "ER" can be machined. The standard material is alloy steel which meets NACE MR 01-75 (1984 Editorial Revision) specifications for H2S service (hardness is 18-22 Rc).
