High Test Steel. High test pipe line welding fittings. conforming to CSA Standard or MSS SP•75. are available with physeal
prowties to match with •42,000, 46,000, 52,000. 60.000. 65.000, and over p_si_ minimum yied strengths
Other Ferrous Alloys. Fittings are availale manufactured from ASTM alloy specificatOns other than those listed in the “ASTM Standards”
Non•Ferrous Metals. Fittings of relatively common metals. such as aluminum. nickel, copper, etc.. can be readily furnished; production is
limited only be availability of raw materials. The same is true of less common metals, such as the varbus grass of Hastelloy, Inconel,
Incohy, Monel. Alloy•20, rare types of stainless steel and other unusual analyses

manufacturing forming processes
The manufacturing processes for pipe fittings includes forging and shaping operations. As well as pressing, hammering, piercing, extruding, upsetting, rolling, bending, fusion welding and machining. Or the processes of combination of two or more of these operations.
During the manufacturing steel pipe fittings, below activities shall be noted:
1, Injurious imperfections, welding defects shall be not created.
2, After shaping or forming the fittings in a suitable temperature, it shall be cooled in a appropriate environments to a temperature that below the critical range. And no defects shall be made during the cooling procedures. The cooling rapid shall be not more than in the air.
3, Suitable inspection shall be performed after manufacturing. (Hydrostatic test, hardness test, tensile test etc)
