1. Since most pipe fittings are used for welding, in order to
improve the welding quality, the end parts are beveled, with a
certain Angle and a certain edge. This requirement is also strict.
The surface quality and mechanical properties are basically the
same as pipes. For the convenience of welding, the pipe fittings
are of the same steel grade as the pipe to be connected.
2. All pipe fittings should be surface treated. The iron oxide on
the inner and outer surfaces should be sprayed off by shot peening,
and then coated with anticorrosive paint. This is for export needs,
moreover, in order to facilitate transportation to prevent
corrosion and oxidation, we must do this work.
3, is the packaging requirements for small pipe, such as export,
you need to do wooden cases, about 1 cubic meter, the number of
elbows in the box can not exceed about a ton, the standard allows
the set, that is, a large set of small, but the total weight
generally can not exceed 1 ton. For large pieces y needs to be
packed individually, like 24 "must be packed individually. Another
is the packaging mark, the mark is to indicate the size, steel
number, batch number, manufacturer's trademark, etc.
