Type and Construction
Welding outlets are in accordance with EEMUA–234, Section 6. The components are manufactured by hot forging and machining from extruded bars (solid or hollow).
Dimensions
The dimensions and tolerances are suitable for welding to seamless and seam-welded pipes to EEMUA – 234. The branch size covered is from ½ in./ 16 mm to 16 in./419 mm. Other branch sizes are available on request. The welding outlets covered are suitable for application to header sizes from ½ in./16 mm to 38 in./965 mm. The sizes of the header pipes for a given branch size are consolidated in accordance with MSS SP-97, Section 3.3 and Figure 1, whereas the gap distance between the header pipe radius and the fitting inlet radius doesn’t exceed 1/16 in./1.6 mm. The design of the self reinforced connection is in accordance with B31.3 Section 304.3 suitable for both 16 and 20 bar pressure ratings. The additional design feature is the smooth entry into the connection to reduce the turbulences. The overall dimensions are based on EEMUA -234, Section 6, Table 6.1.
