The Mustang® Corrosion Coupon Holder (MCCH) secures a corrosion test coupon in the flowing gas by using an orifice fitting. The MCCH allows monitoring of internal corrosion rates throughout a pipeline system without the need of additional access ports.
Metal loss coupons are widely used to measure the rate of internal corrosion in natural gas pipelines. The MCCH can be used extensively in transmission pipeline systems where orifice fittings already exist for other purposes.
The MCCH is used with a standard orifice plate seal unit (available separately).
