Injection Quills

Crystal's range of Injection Quills

Overview

Injection Quills are Special Purpose Products, used widely for Treatment, Mixing, and Neutralizing of Process Products in Petroleum, Chemical, Petrochemical, Power and Allied Industry.

Primary purpose of employing injection quills in the process system is to ensure complete mixing between the two process fluid – between the fluid in the main header pipe and the other being introduced through the quill.

Application

Injection Quills provide an easy solution for uniform and complete mixing of process fluids. The quill injects / introduces process fluid at the centre of the main header – in the form of solid jet or spray – thus ensuring the mixing of process fluids and preventing any channeling effect at the main header pipe side walls.

This method of injection of liquid finds wide application with a wide range of process fluids – corrosive, flammable, acids etc. – easily introduced in the system without the need for consideration of special equipments for handling and mixing.

Construction

Depending upon the process fluids handled the construction material of Injection Quills 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 and constructed such special purpose Injection Quills with Incolloy® / Hastelloy B3® cladded for the Oil Refining Industry.
