Strainers
Den Holder is a manufacturer of several types of strainers, screens and sieves which are designed in accordance with our clients’ requirements or any international standard. Strainers can be manufactured from pipe, fittings, plate or castings.
Standard designs are T- and Y-type strainers, bucket-type strainers and conical strainers. Other designs can be engineered by us and checked for strength and open area ratio to achieve the lowest possible pressure loss. All strainers are manufactured to the highest standards of accuracy so as to be perfect safeguards with minimum pressure loss.
Design, manufacturing and testing are covered by our ISO 9001 Quality System and all required documentation such as WPS/PQR and NDE reports can be included.
