The advantages and characteristics of seamless elbows

The advantages of seamless elbow pipe fittings are as follows: sanitary: PE-RT can be recovered for use without polluting the environment. However, PEX cannot be recovered and secondary pollution will occur. Development trend of seamless elbow pipe: The seamless elbow material not only has qualified creep rupture curve, but also the pipe quotation is moderate, and the construction is convenient and convenient compared with other kinds. The connection method belongs to the standard mutual melt hot melt connection method which is reliable at the present stage. The pore diameter of the pipe fitting part is larger than the inner diameter of the same standard pipe.

Seamless elbow can withstand pressure for a long time: seamless elbow pipe fittings are divided into; Gb elbow has higher pressure resistance function. But due to various factors, the practical wall thickness of the floor heating pipe is generally 2mm. Under this wall thickness, all kinds of pipes can meet the needs of floor heating, and the pressure resistance advantages of seamless elbow pipes are not shown.

Low-temperature and heat-resistant impact: PE--RT and PEX have better low-temperature impact resistance. During winter construction, the pipe is not easy to be cracked by impact, which increases the flexibility of construction organization.

The pressure resistance function of seamless elbow is better: but due to various factors, the practical wall thickness of floor heating pipe is generally and under this wall thickness, all kinds of pipes can meet the needs of floor heating, and the pressure resistance advantage of GB elbow pipe can not be shown; Thermal conductivity: The pipe used for floor heating needs to have good thermal conductivity.

In piping systems, seamless elbows are pipe fittings that change the direction of the line. According to the Angle, there are 45° and 90°180° three commonly used, in addition, according to the needs of the project also includes 60° and other abnormal Angle elbow. Seamless elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics.

The connection modes with the pipe are: direct welding (commonly used) 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, butt welding elbow and so on. Other names: 90 degree elbow, right Angle bend, etc.
