FhaplT h q h Ilrbrr,.. Scientific laboratory procedures are f raw material analysis to control of forging techniques, every step in he production oF Ladish fittings ir originally deterrnined and censtantly reviewed. M a n y series of chemical and physical tests, various of which are illustrated on following pages, are the foundation on which these men exercise metallurgical controls over production processes.

Since carbon ir the most vital single element of steel, directly affecting strength, toughness, ductility and resistance to shock and abrasbn, the Ladish Chemical Laboratory i s. The particles are rnagnetkally attracted t o flaws which thus become visible.

Non-fenous pieces are immersed i n a fluorescent l i q u i d a n d then, after rinsing, scanned with ultra-violet "black light" under which m i nute imperfections are readily visible. Metallography, the e x e i n a t i o n of mic structure of metals reveal6 previous thern history, grain size, phase composition a n d i n cates to the metallurgist important engineeri characteristics.

Measuiing relativo toughness of metal determines its ability to withstand suddenly applied impact loads. A pendulum type impact testing machine i r used in the Ladish metallurgical laboiatoiy to pedorm hundmds of Charpy and lzod tests daily on notched bar samples. Atxurdiely f o h e d test b a n are rubjected to fluctuat. Exact determination of such important physical properties as s t a t i c strength, y i e l d strength, elongation, reduction of area and elasticity of metal i r made in the Ladish laboratory on this , pound hydraulic Tensile Testing machine.

These physical tests are perfonned over wide ranges of temperature. In common with al1 other chemical and metallurgical tests contributing to Ladish Controlled Quality, tensile examination is made of every lot of steel used b y Ladish to assure its compliance with specifications.

Past experience with saddles indicates that while they reinforced the area immediately adjacent to the outlet undesirable rigidity developed in the crotch and side wall portions of the Iine.

Further, the restriction of geometric adjustment of the line caused stress eaks which have undoubtedly contributed to many of t e past failuro which have been associated with saddles. The unique design of the Ladish Split Tee eliminates such faults. Consisting of two half tee sedions, ib area of reinforcement extends completely around both line and branch pipes and for a generous distance along the line pipe on each side of the branch connection.

The two halves are welded together along the line of bisection with heat kept safely away from direct contact with the main line. Additional sup ort S gained b welding the branch outlet of the Split ee to the branch hne. The joint opposite the branch i s made with an exterior overlapping reinforcement strip which provides ample adjustment within the permisible ran e of dimensional tolerances to fit around the main line.

Futting and fitting on the job site are eliminated. The connection is completed by welding the overlapping strip to the mating half of the Split Tee. Welding to the line pipe as well as total weld deposition for the entira connection is held to a minimum.
