Injection and Sample Lances

Injection and sample lances

Injection lances (or fittings) are generally used within dosing systems as a means of introducing chemicals into main pipeline streams. Sample lances are used to extract samples for quality monitoring.

Prochem manufactures a wide range of both withdrawable and fixed fittings. Fixed fittings are installed semi-permanently and can only be removed with the main de-pressurised. On the other hand, withdrawable injection fittings (WIF) offer much more versatility – they can be withdrawn whilst the main is under pressure. All Prochem WIF’s are designed for maximum ease of use and incorporate anti blow-out stops to prevent inadvertent complete expulsion of the lance during withdrawal
