» We Provide Wide Range Of Bolt On Jackets
» Material Of Construction Is Mainly Stainless Steel & Carbon Steel
» For Carbon Steel We Provide Temperature Resistant Aluminium Paint
Mainly Below Are Two Types Of Jacket
» Bolt On Jackets
» Clamp On Jackets
Bolt On Jackets
» We Have Designed Special Type Of Bolt On Jackets To Sustain High Pressures.
» These Jackets Have Dimple On Surface To Increase Stiffening.
» As Due To Stiffening Material Thickness Required Is Less Which Reduces Weight Of Jacket.
» Hence Handling Of Jackets Is Much Easier.
» Minimum Size Offered Is 2" Valve.
» These Are Customised As Per Customer Requirement
Clamp On Jackets
» These Jackets Are Used Where There Is Limitation Of Space For Assembly.
» Range Varies As Per Customers Requirement.
» Jacket can be fabricated in stainless steel, carbon steel as well as aluminium.
» Carbon steel are preferred for reducing cost. However heat resistant painting is required to avoid it from corrosion.
» Aluminium Jackets rarely used for high heat transfer rates. They are last option as are much costlier compared to CS & SS.
» Stainless Steel jackets are resistant to corrosion as well as have good heat transfer rates. They have much longer life as compared to CS.
» Inlet & outlet connection are provided as per customer requirement. 3/4", 1/2" NPT(F) etc couplings.
» Also flanged connections can be provided for high pressure ratings as per customers requirement.
» Jackets can be designed to cover only valve or adjacent spool flanges.
» For spool flanges of different size other than valve we have also developed special steam jackets as below.
» Generally operating pressure is about 10-15 bar(g).
» Temperature ranges from 200-250oc
» Dimple are provided on outer side of jackets for strengthening jacket.(image for reference).
» Jackets work on principle of heat transfer by conduction.
» Inlet Ports are provided at top & at opposite ends for each half jacket as shown above.
» This triggers the flow of steam in opposite direction for both halves.
» Due to this, heating is uniform at both ends & through valve.
» No localised heating as like cast jacket as each half acts as independent complete chamber.
» Steam Flows through complete half maintaining uniform temperature
