brief introduction
Elbow is a commonly used connecting pipe fitting in plumbing
installation. It is used for the connection at the bend of the
pipeline and to change the direction of the pipeline.
Other names: 90 ° elbow, right angle bend, love bend, stamping
elbow, pressing elbow, machine-made elbow, welding elbow, etc.
Purpose: connect two pipes with the same or different nominal
diameter to make the pipeline turn 90 °, 45 °, 180 ° and various
degrees.
Bending radius less than or equal to 1.5 times of pipe diameter
belongs to elbow, and bending radius greater than 1.5 times of pipe
diameter belongs to elbow
technical requirement
1. Since most of the pipe fittings are used for welding, in order
to improve the welding quality, the ends are turned into grooves,
with a certain angle and a certain edge. This requirement is also
strict. There are regulations on the thickness of the edge, the
angle and the deviation range. The surface quality and mechanical
properties are basically the same as those of pipes. For the
convenience of welding, the steel grade of pipe fittings and
connected pipes is the same.
2. That is, all pipe fittings shall be subject to surface
treatment, and the iron oxide scale on the internal and external
surfaces shall be sprayed off by shot peening, and then coated with
anti-corrosion paint. This is for export needs. Moreover, in China,
it is also to facilitate transportation and prevent corrosion and
oxidation.
3. That is, the requirements for packaging. For small pipe
fittings, such as export, wooden boxes need to be made, about 1
cubic meter. It is stipulated that the number of elbows in such
boxes can not exceed 1 ton. The standard allows suits, that is,
large sets and small sets, but the total weight can not exceed 1
ton. For large pieces y, a single package is required. For 24 ", a
single package is required. Another is the packaging mark, which
indicates the size, steel number, batch number, manufacturer's
trademark, etc
Carbon steel is an iron carbon alloy with carbon content of 0.0218%
~ 2.11%. Also called carbon steel. Generally, it also contains a
small amount of silicon, manganese, sulfur and phosphorus.
Generally, the higher the carbon content in carbon steel, the
greater the hardness and strength, but the lower the plasticity.
Carbon steel products mainly include various bolts, studs, screws,
nuts, washers, self tapping screws, assemblies, retaining rings,
rivets, pins, flat keys, thread sheaths, etc. Standards include GB
(national standard), DIN (German standard), ISO (International
Standard), ANSI (American Standard), BS (British Standard), JIS
(Japanese standard), etc. non standard products can also be
processed according to drawings or samples.
Surface treatment mainly includes blackening, galvanizing, nickel
plating, copper plating, Dacromet, carburizing, etc.
The products are widely used in all kinds of machinery, machine
tools, automobiles, molds, hydraulics, petroleum, chemical
industry, energy, pipelines, pumps and valves, ships, electronics,
electricity, instruments, meters, environmental protection, water
treatment, industrial control, food machinery, medical equipment,
construction engineering, aerospace, furniture and product
maintenance, and are deeply trusted and praised by our customers.
