While VGS figs are normally ienifie by he nomal size, always check he acual OD of he pipe an figs o be connece, as some markes i is cusomary o refer o ifferen OD pipes wih he same nomal size. For example: The nomal size 2-1/2 ( ) is referre o 2.7 (73 ) pipe OD IPS an 3 (7 ) pipe OD S, S, DIN (ISO), JIS or KS pipes.

VGS groove pipg sysems require a roll or cu-groove o be applie o he pipe ens beg connece. The groove imensions an configuraions may vary epeng on several facors clug pipe maerial, wall hickness an esire workg pressures. Roll groovg is he mos coon pracice an can be performe he fabricaion shop or he fiel on he job sie. u groovg on he oher han is primarily performe a he facory or fabricaion shop, as cu groovg maches are no as coon or porable as roll groovg maches. ll roll an cu grooves mus mee he specificaions an requiremens of NSI/WW 0 (laes eiion) an ISO/FDIS For oher pipe sizes no specifie NSI/WW 0 (laes eiion) an ISO/FDIS 12-12, refer o he relaive groove specificaions shown his manual or he VGS prouc caalog. When groovg pipe, i is preferable o sar wih pla-en pipe, alhough some cases he use of bevele pipe is accepable provig ha he wall hickness is sanar or hner an he bevel is 37 1/2 ± 2 1/2 (NSI.2). Spiral wele pipe may also be use as long as he welg beas are remove from all of he sealg an seag surfaces.

Max Tolerances Groove Wih ( Dimension): is o be measure beween verical flanks of he groove sie walls. The corners of he groove may be roune as long as he K an 1 values are wih he maximum allowe olerances as shown below. To achieve opimum jo performance he K imension shoul be as small as possible. When processg a roll groove he mache operaor shoul manage he fee pressure of he upper roll se so as o achieve he bes possible groove profile. To check: Use a ruler o ensure ha he 1 an K imensions are wih he above lise olerance imensions. Groove Diameer ( Dimension): The groove iameers are average values. The groove mus be of uniform eph aroun he enire pipe circumference. Mimum Wall Thickness ( Dimension): The is he mimum allowable wall hickness ha may be roll-groove.
