In pulp mills with common blow lines from a series of batch digesters to blow tanks often problems are experienced in respect to short life of blow valves, blown out gaskets, shaking of the equipment, short life of targets in the blow tanks, etc. The reason for these damages are leaking blow valves, kinetic energies in the moving pulp, deficiencies in the blow line design and improper programming of blow valves, diverter valves and isolation valves. The kinetic energies and flashing of cold liquor in the blow lines create shock waves, which are well above 10000 psi. Several suggestions are made, which are reducing the damages experienced in the blow line system.
Products & Services
Air blow guns attach to air lines for the manual actuation and/or control of air discharge. They are used primarily for debris removal and purging, non-contact part cleaning and drying, and general laboratory or industrial applications.
Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow.
Composite and fiberglass molding services perform injection molding, blow molding, compression molding, rotational molding, thermoforming, and dip molding.
Valve repair services repair and rebuild used valves.
Industrial valves are classified in many different ways. They can be distinguished by material of construction, media handled, and/or application.
