Carbon Steel Pipeline Fittings For Pressure Usage 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. ipe
fitting, as the name suggests, is the part that connects bai sons
into a pipe, which plays the roles of connecting, controlling the
direction, diverting, supporting the pipe and sealing in the
pipe.This article mainly introduces what the pipe fittings are and
what the standards of pipe fittings are.
According to the pipe fitting, the pipe fittings can be classified
into six categories: pipe fittings connected with pipes, including
flanged pipe fittings, live pipe connectors, clamped sleeve
fittings, pipe band fittings, etc.Pipe fittings used to change the
direction of the pipe, including elbow pipe fittings and elbow pipe
fittings;Pipe fittings used to change the pipe diameter, including
reducing pipe fittings (i.e., reducing pipe fittings), reducing
elbow pipe fittings, branch pipe bench pipe fittings, reinforcement
pipe fittings;Fittings for adding branches of pipelines, including
tee fittings and stone fittings;Pipe fittings used for sealing
pipes, including gasket pipe fittings, head pipe fittings, flanged
blind plate pipe fittings, pipe plugging fittings and welding plug
pipe fittings;Pipe fittings used for fixing pipelines, including
clamping ring pipe fittings, decoupling pipe fittings, lifting ring
pipe fittings, bracket pipe fittings and bracket pipe fittings,
etc.
