The three-way fittings, pipe fittings. Branch pipe at the three links, commonly used in the main channel to Equal and Reducing Tees, equal tee to take over the ends are the same size; Reducing tee competent to take over size the same the manifold over size less than competent takeover size. terms of seamless pipe manufacturing three-way, normally used in hydraulic bulging and hot forming two craft manufacturing standards division electricity can be divided into standard, water standard, American standard, German standard, Japanese standard, the Russian standard, such as Standard ASME B16.9-2007 ASME B16.25-2007 ASME B16.5-2007 EN10253-1-1999 EN10253-2- 2007 EN10253-3-2008 EN10253-4-2008 DIN2605-1-1992 DIN2605-2-1995 JIS B2311-2009 JIS B2312-2009 JIS B2313-2009 GB/T12459-2005 GB/T13401-2005 GB/T10752-2005 SH / T3408-1996 SH/T3409-1996 SY/T0609-2006 SY/T0518-2002 SY/T0510-1998 DL/T695-1999 GD2000 GD87-1101 HG/T21635-1987 HG/T21631-1990 size seamless size: 1/2 "~ 24" DN15 ~ DN600 seam size: 4 "~ 78" DN150 ~ DN1900 wall thickness sch10 sch20, sch30, std, sch40, sch60, xs, sch80, sch100, sch120, sch140, sch160, xxs, sch5s, sch20s , sch40s, sch80s maximum wall thickness: 150mm Material Carbon steel: ASTM / ASME A234 WPB-WPC Alloy: ASTM / ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP 911 stainless steel: ASTM / ASME A403 WP 304-304L-304H-304LN-304N ASTM / ASME A403 WP 316-316L-316H-316LN-316N-316Ti ASTM / ASME A403 WP 321-321H ASTM / ASME A403 WP 347-347H low temperature steel: ASTM / ASME A402 WPL 3-WPL 6 high-performance steel: ASTM / ASME A860 WPHY 42-46-52-60-65-70 Production bend, squeeze, push system, molding, machining and other applications industry three links widely in many industrial fields, such as electricity, oil and gas, petrochemical, chemical, shipbuilding, heating, papermaking, metallurgy, etc.. seamless three links of the three links, the parameters of the production range sew three links outside diameter of 1/2 "to 24" 4 " ~ 78 "diameter wall thickness 2mm ~ 150mm Product Type tees, reducing tees
