Socket-Weld & Threaded Olet Integrally reinforced contoured branch connections. Available in all material grades and wall thicknesses. Additionally complies with MSS-SP-97 and B16.11 (Class 3000,6000..)
Lateral & Elbow Olet Integrally reinforced branch connections for installation on straight runs or elbows. Available in butt-weld, socket-weld, and threaded configuration
Butt-Weld Olet Integrally reinforced contoured branch connection in outlet sizes from 1/4" to 60". Available in all material grades and wall thk. Additionally complies with MSS-SP-97 and B16.9
Nipple Olet Integrally reinforced branch connection of one piece construction which eliminates costly welds and provides convenient attachment of socket-weld and threaded valves and instruments. Available in standard lengths of 3-1/2" and 6-1/2"
Expanded Olet Integrally reinforced branch connection designed for use where branch pipe is larger than run pipe. Eliminates bull head tees or standard tees in combination with concentric reducer
Sch 5S & 10S Olets Integrally reinforced branch connections for use on Sch 5s & 10s stainless pipe. Designed to minimize pipe distortion caused by welding and to reduce installation time
Therma-Olet Weld on, integrally reinforced threaded (Class 3000 and Class 6000) and flanged (Class 150 thru Class 2500) branch connection for thermowells in heavily insulated pipe
Flanged Olet Forged flanged integrally reinforced outlet fitting available in Class 150 thru Class 2500 flange ratings. May be specified in any combination flange type, run size and branch size
Vesselet Integrally reinforced, contoured-insert type branch connection ideally suited for cyclical and for high pressure/temperature services. Patented circular design reduces weld volume, permits automatic welding and lends itself to Non-Desctructive Examination
45° & Elbo Vesselet Integrally reinforced, contoured-insert type branch connection ideally suited for cyclical and for high pressure/temp. services. Patented design reduces weld volume and lends itself to Non-Destructive Examination
Swage Nipples Design provides special internal reinforcement at critical stress concentration areas. Available as concentric and eccentric in all material grades
Thermalet Integrally reinforced contoured-insert type branch connections, threaded (Class 3000,6000) and flanged (Class 150- 2500) for thermowells in heavily insulated pipes. Moves attachment weld away from instrument top. Patented design reduces weld volume, permits automatic welding and lends itself to Non-Destructive Exam.
Nozzelet A traditional insert welding outlet contoured to fit the inside diameter of the run pipe vessel wall. Available in butt-weld and flanged configuration
Bosset A weld-on connection in Class 3000 and Class 6000 ratings in socket-weld, threaded or combination threaded and socket-weld design
Safety Relief Valve Vesselet Special support nozzle designed to reduce flow induced vibrations. Engineered for temp.pressure and flow conditions. Also considers fatigue and is designed to accommodate stresses induced from opening and closing of the valve and seismic condition
Bottlet A contoured-insert Vesselet with a butt-weld projection inside the vessel for through-the-wall piping service. Projection ends are beveled for easy welding and for Non-Destructive Exam.
Studdet Designed for mating flanges to vessels or tanks utilizing a contoured insert type connection. Available in all flange sizes and pressure ratings. Patented design reduces weld volume, permits automatic welding and lends itself to Non-Destructive Exam.
Studding Outlet Designed for mating flanges to vessels or tanks economically. Manufactured for either ID or OD installation
