Rectangular pipe elbow
Thread Content
Please tell me, are there any specifications for rectangular pipe elbows? Such as turning radius, etc. Thank you
I have seen this in the "Technical Regulations for the Design of Flue, Air and Pulverized Coal Pipelines in Thermal Power Plants", but I cannot upload the data. You can search elsewhere to see if it meets your pipe requirements.
Technical regulations for the design of smoke, air and pulverized coal ducts in thermal power plants 7.2.1 Rectangular flue duct elbows should meet the following requirements. They should be concentric gentle bends or sharp bends with rounded inner and outer edges. The bending radius or the ratio of the inner and outer edges to the radial width of the elbow inlet should be a gentle bend.: R/b=1~2 sharp turn: rw/b=rn/b=0.4~0.6 If the layout is difficult, you can use an external chamfer to make a sharp turn!
May I ask how rw/b=rn/b are equal? Is it a publishing error? 4 ] "
