H.P. Corrosion Coupon Hold
For High Pressure Access System
Sewon Coupon Holders are designed to be specifically compatible with High Pressure Access Systems. The coupon holder is attached to the solid carrier plug assembly by means of a left-handed thread connection to ensure that it does not become loose during the retrieval procedure. The coupon holder is attached by means of a set screw arrangement and incorporates an orientation keyway feature to automatically align installed strip coupons parallel to the fluid flow. Coupon holders are manufactured from 316L stainless steel or Duplex stainless steel to meet NACE MR0175 requirements for sour service. Mounting hardware is also manufactured from same material as coupon holders and is supplied with coupon holders. Insulators are fabricated from Teflon and are supplied with the coupons. Coupons are ordered separately.
