304 Stainless Steel Elbow Stair Handrail Elbow 90 Degrees Welded
Industrial Elbow Sanitary Elbow Fittings It is required to control the radius of curvature.For example, if
the radius length is 1.5D, the radius of curvature must be within
the required tolerance.Since most of these 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 more strict. How thick the edge is, how much
the Angle is and the range of deviation are specified, and there
are many more items in geometric dimensions than pipe
fittings.Elbow surface quality and mechanical properties are
basically the same as pipes.For welding convenience, the steel
material should be the same as that of the pipe to be connected.
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. | Size | 1/2"-2 4" ,DN15-DN600 24"-72",DN600-DN1800 | | Material | ASTM | Carbon steel: (ASTM A234WPB,,A234WPC,A420WPL6. | | Stainless steel: (ASTM A403 WP304,304L,316,316L,321. 1Cr18Ni9Ti,
