Socket bend

The socket elbow is a kind of high pressure elbow pipe connection fitting which is mainly formed by forging blank of round steel or ingot mould and then shaped by lathe machine.It is a kind of pipe fittings for forging socket series.

classification

Common standard

Common standards for socket elbow include GB/ t14383-93,GB/ t14383-2008, American standard ASME B16.11, petrochemical standard SH3410, chemical engineering department standard HG/T21634, etc

Specification form

According to the pattern is divided into 90 ° and 45 ° elbow socket socket bend

According to common standards, the specification of socket elbow is DN6, DN8, DN10, DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80 and DN100.The commonly used order specification is DN15- DN50.If there is beyond the scope of this specification, you can communicate with the customer about the drawing design and processing.

Classes.

By pressure grade: 3000LB, 6000LB, 9000LB or SCH80, SCH160, XXS

Commonly used manufacturing material

Commonly used raw materials for pipe fitting are carbon steel, stainless steel, alloy steel, etc.

Common brands of carbon steel are Q235, 20#, A105, etc.

The common stainless steel brands are 304, 304L, 316, 316L, 321, 00Cr17Ni14Mo2, etc.

The common brands of alloy materials include 15CrMo, 1Cr5Mo, 16Mn, 12Cr1MoV, F11, F22, 10CrMo910, etc

Other materials: copper alloy, nickel alloy, etc.

Application field

Mainly applied to petrochemical industry, medicine and health care, electric power, spaceflight, war industry, fire protection, metallurgy, shipbuilding, gas, nuclear power, and the environmental protection requirements under pressure is high, the size precision and other departments and fields.

Matters needing attention

Socket pipe parts over size is divided into two kinds, namely A series (Ⅰ series) to take over the size and B series (Ⅱ series) to take over the size or the imperial takeover (i.e., A series of size) and metric over (B series size).In addition, some standards directly stipulate that the takeover size is A series, such as ASME B16.11 and SH3410 standards.Some standards have two size, production and processing, the need to implement the control of size of these standards GB/T14383-2008, GB/T14383-93, HG21634 etc, if use did not provide the choice of nozzle size, generally the default for A series.However, it is important to note that the standard HG21634, if it gives the takeover A, should use the b-series takeover size.
