industrial-drilled-threaded-tapered-straight

Drilled Threaded Assemblies Tapered & Straight


The most common type of well assembly style and size. Threaded well allows for insertion directly into process lines through pipe TEE’s or Laterals. They can also be inserted into tanks with half couplings or threaded outlets. They are available with a straight shank for longer wear and tapered to limit flow restrictions or when velocity considerations must be taken into account.

industrial-drilled-threaded-tapered

Drilled Threaded Assemblies Alloy Metals, Tapered


Other environments, corrosive conditions or when additional strength is required. Bar stock wells can be fabricated in a number of austenitic, ferritic or martensitic stainless steels, nickel alloys, chrome-molys or other specialty metals. Wrench flats are machined into the neck for installation since these alloys are usually only available in round stock. Wells are available with standard tapered, straight or step down shanks.

industrial-drilled-weld-in

Drilled Socket & Weld-in Bar Stock Well Assemblies


Socket and Weld-in bar stock wells are used in high temperature, high pressure service, most often steam. A regular product for the power industry where absolute leak proof permanent connections are mandatory. Socket wells are inserted into process lines through pipe TEE’s or Laterals or on to branch lines with socket outlets. Weld-in wells are welded directly into heavy wall tanks.

industrial-van-stone

Van Stone Well Assemblies Tapered, Straight


The Van Stone thermowell is machined from a single piece of bar stock with a neck the same as the face diameter of a 1″ or 1 1/2″ flange. This design allows for sandwiching of the van stone between the vessel process flange and a securing slip on flange. This design offers two advantages:

1. Any weld stress is eliminated.
2. The slip on flange not being exposed to the process conditions can be of a less expensive material.

Process Connection:Connects to 1″ or 1 1/2″ Mating Flange
Well Material:All grades of Stainless Steel, Nickel alloys, Hastelloy, Specialty metals
Element Type:Platinum, Copper, Nickel
TRC:.00385, .003916, .003923, .00427(CU), .00672(NI)

industrial-pipe-well-flanged

Pipe Well Assemblies Plain, Threaded, Flanged


A lower cost alternative to bar stock wells where pressure and velocities are low. Pipe wells are available in schedule 40, 80, 160 or XX strong, 1/4″ to 1″ pipe size. Plain wells can be welded directly into a tank or simply free hanging, threaded wells are supplied with a welded on NPT bushing for a threaded process connection, flanged pipe wells connect to a mating flange for a stronger connection. Pipe wells are commonly supplied in lengths up to 20 feet.
