Ductile iron grooved pipe fitting flexible and rigid couplings for fire fighting

Product DescriptionFeatures: iron grooved coupling1) Material: ductile cast iron ASTM-A5362) Reducing installation costs3) Flexibility and rigidity4) Joint reliability5) Isolate noise and vibration6) Convenient joint7) Application: Power plant; Heating,ventilation and air conditioning; Industrial plant; Water treatment; Plumbing; Fire protection; Mining and mine processing; Oil field; Marine. This kind of coupling is designed for the pipe bearing moderate pressure. It allows controlled angle, linear and rotational movement at each joint and provides the added advantages of expansion, contraction and deflection. This is usful to accommodate uneven laying surfaces, and movement from thermal changes, setting, seismic effect or other causes. Flexible coupling can be used in fire protection system, feed water, gas system and etc.Size SheetThe world’s most advanced automatic disa molding line and sand processing ensure the quality of each product.Tilting shot blasting machineTestIn order to guarantee the quality, the company introduced German brand spectrograph, advanced KRX-TG, Metallographic image analyzer, gasket test equipment, green sand test equipment, cast iron assay analysis equipment, pressure inspection equipment etc. Thus a fast, accurate quantitative analyzing approach is provided for scale productionFAQQ: Are you trading company or manufacturer ?A: We are a factory.Q: How long is your delivery time?A: Generally 15 days after the down payment.
