Abstract: The present invention enables a manufacture of thickwalled fittings subjected to the effects of high temperatures, pressures and (or) aggressive media. Fittings manufactured according to the invention are designed for a high flow velocity. The formation of a curved fitting is effected by two pairs of dies, one thereof has flat working surfaces and the other, arcuate recesses. A tubular blank is successively reconstructed by said pairs of dies in the course of one or two strokes of a press.

Abstract: The invention relates to manufacturing of T''s, crosses and like fittings, particularly those intended for operation at elevated pressures and temperatures. The method involves the use of three pairs of dies effecting compressing and upsetting of a tubular stock, whereby it becomes possible to treat a stock having the ratio of its wall thickness to the internal diameter in excess of 0.15 to 1.
