Note: Socket-Welding Reducer Inserts of sizes and reductions other than thoseshown are available on request.
To minimize the possibility of cracking of the fillet welds, itis recommended that the shank portion of the reducer bewithdrawn approximately 0.06 in (1.5 mm) away fromcontact with the bottom of the socket before starting theweld. Likewise the pipe is to be kept away from contactingthe bottom of the reducer socket before welding.

*REDUCED FITTINGSMethod of designating outlets of reducing Tees and Crosses.In the case of reducing tees and crosses the size of the largest run openingshall be given first, followed by the size of the opening at the opposite end ofthe run. Where the fitting is a tee, the size of the branch is given last.Wherethe fitting is a cross, the largest side-outlet is the third dimension given,followed by the opening opposite.*Reducing Tees, elbows and crosses, both Socket-Welding and Threaded, areavailable on request. Alternatively, reductions may be achieved with the use ofSocket Welding Reducer inserts, or Hexagon (Threaded) Bushings.
IDENTIFICATION, MARKINGSHuiyi Company FORGED STAINLESS AND ALLOY STEEL FITTINGS are clearly marked, wherever the size and the nature of thefitting permits, for quick and accurate reference as to size, pressure class, and material.
