Process of chemical injection quills manufacturing : salient features

The construction material of Injection Quills depends upon the process fluids handled. It varies from carbon steel, stainless steel to high alloy steels such as Inconel®, Incolloy® and Hastelloy®.

Crystal has designed and constructed custom built injection quills for its Clients with the entire unit – consisting of main header pipe and the quill assembly - supplied as per requirements.

  • Main header pipe material : carbon steel, low alloy steel (1Cr-½Mo; 2¼Cr-1Mo) of thicknesses upto 2" (50.80 mm), overlayed or lined with Inconel® / Incolloy®.
  • Forged taper quills of stainless steel, Inconel®, Incolloy® and Hastelloy®

Crystal has carried out forging of these taper quills of weight upto 600 lb (300 kg), heat treatment and testing for physical and chemical properties meeting to relevant material specifications including corrosion resistant properties as per ASTM G28.

The wide range of materials involved, the welding and forging of these materials is an indication of the rich metallurgical experience Crystal has.

Crystal is one of the first companies in the world to have designed, constructed such special purpose Injection Quills with Incolloy® / Hastelloy B3® cladded for the Oil Refining Industry.
