Roto Lined Equipments

WARRANTY OF 24 MONTHS FOR 2 MM THICK LINING

This lining is a new computer controlled lining technology using rotational motion of object along with sintering process. This process creates a seamless lining with virtually uniform lining thickness.

High performance polymers like HDPE, PP, ETFE, FEP & PFA are available in ROTOLINING. It can be supplied from 0.5mm to 5mm lining thk .It can also be supplied with FDA confirm certification and Antistatic electro conductive lining.

ADVANTAGES OF ROTOLINING :
(FLEXIBLE & ECONOMICAL)

1) Better chemical resistance than coating as polymer is heated only once, to get required thickness of lining
(No repeated heating like coating)
2) Any shape can be lined.
3) Quick completion of lining.
4) Better bonding of lining to substrate because of rotating movement.
5) In case of Header & piping less no. of joints required.
6) Seamless construction without weld joints.
7) Suitable for full vacuum.
8) Suitable for heat transfer application because of better bonding.
9) Can take thermal & physical shock
10) Fast delivery of valves compared to moulded lining.
11) Antistatic - Conductive lining of equipment, Piping, Fitting & Valves possible.

APPLICATION OF ROTOLINING :

1) Jacketed Reactors & Receivers
2) Inlet & outlet Header for Reactor
3) Pumps Casing
4) Shell & tube heat exchanges with lining from inside of tubes
5) Monoblock Tanks & vessel without main body flange on shell
6) Piping with less no. of joints
7) Diaphragm Valves, Ball Valves etc.
8) Agitators
9) Spares for glass lined reactors.

1) HDPE : Hard, smooth Finish, good Stress crack resistance FDA Approved less expensive than SS & FRP.

2) PP : Hard, smooth Finish, good Stress crack resistance FDA Approved less expensive than SS & FRP good resistance to many organic chemicals.

3) PVDF : It is a tough material with excellent cut through and abrasion Resistance properties. It is resistant to strong acids and bases but are readily dissolved by polar organics. This is the lowest Cost fluoropolymer.

4) ETFE : It is a tough material with excellent cut through, abrasionResistance and impact properties. It is resistant to most Chemicals. It is FDA compliance.

5) FEP : Chemical resistance is similar to PTFE & PFA. It is used in the semiconductor and pharmaceutical applications due to the Excellent chemical resistance, high purity, and FDA Compliance.

6) PFA : PFA has better mechanical properties than PTFE or FEP. Chemical resistance is excellent similar to PTFE. It is used in the semiconductor and pharmaceutical applications due to the excellent chemical resistance, high purity, and FDA compliance. This coating is most expensive because of high cost of material & high temperature processing.
