Nominal quvur hajmi (NPS):1/2 dyuym (DN 15) dan 24 dyuymgacha (DN 600) va undan kattaroq.
Tashqi diametri (OD):OD NPS bilan farq qiladi. Masalan, 1/{1}} dyuymli gardishning OD diametri taxminan 3,88 dyuymni, 24- dyuymli gardishning OD esa 32,38 dyuymni tashkil qiladi.
Bolt doirasi diametri (BCD):Bu o'lcham gardishning kattaligi bilan ortadi. Masalan, 1/{1}} dyuymli gardishning BCD taxminan 3,25 dyuymni, 24- dyuymli gardishning BCD esa 29,5 dyuymni tashkil qiladi.
Bolt teshiklari soni:Bolt teshiklari soni NPS bilan farq qiladi. Kichikroq o'lchamlarda murvat teshiklari kamroq bo'lishi mumkin (masalan, 4), kattaroq o'lchamlarda esa ko'proq bo'lishi mumkin (masalan, 20).
Bolt teshigi diametri:Bolt teshiklarining diametri NPS bilan farq qiladi. Masalan, 1/2- dyuymli gardish uchun murvat teshigi diametri taxminan 0,88 dyuymni tashkil qiladi.
Uya diametri:Flanjning tagida ko'tarilgan yuzning diametri gardishning kattaligi bilan ortadi.
Hub orqali umumiy uzunlik (LTH):Gardishning yuzidan markazning oxirigacha bo'lgan masofa bo'lgan bu o'lcham ham gardishning kattaligi bilan ortadi.
Flanj qalinligi:Flanjning qalinligi bosim sinfiga qarab o'zgaradi.
Shuni esda tutingki, bu umumiy o'lchamlar va maxsus o'lchamlar ishlab chiqaruvchiga va amal qilinadigan standartlarga qarab farq qilishi mumkin. Aniq va batafsil o'lchamlar uchun ASME B16.5 standartiga murojaat qilish yoki muayyan gardish o'lchami va sinfi uchun ishlab chiqaruvchining texnik xususiyatlariga murojaat qilish tavsiya etiladi.
