2. ① Re-work existing fittings ③ Easily make various types of custom-spec fittings ①②③ ② Modify by specialized welding method

5. Down-sizingDown-sizing Reduced footprintReduced footprint 282mm 108mm e.g. 60series φ1/2 ” x 3/8 ” Less than 50%

6. ・ Reduction of weight Reduction of the number of fittings makes reduction of the equipment weight. ・ Reduction of operating time Reduction of the number of tightening of nuts makes reduction of operating time. Nuts --- 7 pcs. Nuts --- 3 pcs.

8. * Inside of welded part has reliable bead-less form. * No-chemical entrapment.

9. Bead-less construction has no influence on the chemical rinse performance. --- 60 series (Bead-less weld) --- 60 series (standard) --- Blank (Tubing) --- Other inner-sleeve type fitting --- 60 series (Bead-less weld) --- 60 series (standard) --- Blank (Tubing) --- Other inner-sleeve type fitting Rinse test data (3/4”) Time(min.) Recovery(%)

10. 1. Tensile strength Test Destruction strength of welded part is about twice value of tube pulling out strength. Destruction strength of welded part is about twice value of tube pulling out strength. Specimen Destruction strength of welded part Tensile strength of tube 60 series 3/4” fitting welded manifold 3180 N (324.5 Kgf) 959 N 97.8Kgf

11. 2. Pressure Test Burst pressure of a welded part is about twice value, when it is compared with that of a tube. Sample Burst pressure Burst pressure of tube 60 series 3/4” fitting welded manifold6.6MPa3.0MPa Sample Burst pressure Burst pressure of tube 60 series 3/4” fitting welded manifold3.8MPa1.6MPa Ambient Temp. at 25 ℃ High Temp. at 90 ℃

12. Cost Down Weld SystemStandard fitting Reduction of operating time Nuts --- 3pcs. Nuts --- 7pcs. Space reduction 108mm282mm Weight reduction
