GB12459 Standard Long Radius 30 60 90 Degree Water Pressure Carbon
Steel Pipe Elbow
Fittings made from block forgings may only be supplied subject to
agreement between the manufacturer and purchaser. Such fittings
need not meet the requirements of section 7. For applications where
fatigue loading is a concern, required minimum dimensions shall be
furnished by the purchaser. Fittings may be made to special
dimensions, sizes, shapes, and tolerances by agreement between the
manufacturer and the purchaser.
The ways of connecting with the pipe are: direct welding (the more
common way) flange connection, hot melt connection, electric melt
connection, thread connection and socket connection, etc.According
to the production process can be divided into: welding elbow,
stamping elbow, push elbow, casting elbow and so on.Other names: 90
degree bend, right Angle bend, etcCarbon steel elbow can be divided
into long radius elbow and short radius elbow according to its
radius of curvature.Long radius elbow refers to the outer diameter
of the pipe whose radius of curvature is equal to 1.5 times, i.e.,
R= 1.5d.
Product furnished to this specifification shall conform to the
requirements of Specifification A960/A960M, including any
supplementary requirements that are indicated in the purchase
order. Failure to comply with the requirements of Specifification
A960/A960M constitutes non-conformance with this specififi-cation.
In case of a conflflict between the requirements of this
specifification and Specifification A960/A960M, this
specifification shall prevail.Wrought fittings covered by this
Standard shall be in accordance with ASTM A234, ASTM A403, ASTM
A420, ASTM A815, ASTM B361, ASTM B363, ASTM B366, or the
corresponding specification listed in ASME BPVC, Section II. The
term “wrought” denotes fittings made of pipe, tubing, plate, or
forgings.This Standard states values in both SI (Metric) and
U.S.Customary units. These systems of units are to be regarded
separately as standard. Within the text and tables, the U.S.
Customary units are shown in parentheses. The values statedin each
systemare not exact equivalents;therefore, it is required that each
system of units be used independently of the other. Combining
values from the two systems constitutes nonconformance with the
Standard.
