Dimensional tolerances U-tubes acc. to TEMA R.C.B.

 

Length of straight part -0/+5 mm


Flattening (also called “ovality”) at the bend shall not exceed 10% of the nominal tube outside diameter.


Wall thickness in bending part acc. to TEMA RCB 2.31 Minimum tube wall thickness in the bend part (T min)T(min) ≥ (SW × (2×R + D))/( 2× (R+D)where:

 

SW is smallest wall thickness D Nominal outside diameter R radius


Radius tolerance 1) for R 100 mm +/- 3 mm

 

2) for R ≥ 100 mm +/- 5 mm


Straightness tolerance max. 1,5 mm per 1 m


U-Tube ends: plain, vertically cut to the tube axis

 

Tube-bending line, installed at 2007, will allow to produce U-tubes as per such standards:

 

1. ASTM A688/A688M-08


2. ASTM A803/A803M


3. ASTM A556/A556M, ASME SA556


4. ASME SA-688

 

5. ASME SA213 ASTM A213
