PYPLOK® FOR HEATING COILS IN SHIP TANKS

Steam Heating coils form and important component of marine cargo application, this is due to the various high viscosity cargo handled by the ships like crude oil, edible oils etc. At ambient temperature these liquids are difficult to handle due to their high viscosity. Many of these liquids are difficult to handle at ambient temperatures due to their high viscosity. Steam Heated Coils increase the temperature of these high viscosity fluids and decrease their viscosity so that they can be easily handled.

The piping for the steam coils have to be reliable as any leakage can cause the discharge of steam to the cargo and may contaminate it. Also repairing the leak by conventional methods like welding is a big concern as it involves hot work (hence cargo has to be emptied). Hence a safe and reliable connection is needed for heating coils.

Pyplok┬« is an ideal pipe/tube fitting for such applications because it is a reliable and a safe connection.

Pyplok┬« being permanent fitting is tamper proof and very reliable (has references of service life spanning 25 years and still in operation)

Specialized Pyplok┬« fittings are manufactured for Heating Coil Systems where the Primary seal is EPDM to hold steam and the environmental/backup seal is Viton

Pyplok┬« is a 360 degree radially crimped mechanically actuated fitting. It involves no welding at all. It is available in Carbon Steel, Stainless Steel, Duplex, Super Duplex and Cu-Ni. It is a high pressure fitting. For more information please visit Pyplok┬« Page.

Pyplok┬« is easy to install and requires no skilled labour.

The main purpose of the job was to repair the leaks in the heating coil piping in COT and SLOP Tanks.
The reason for the leaks were due to defective welds of socket weld fittings during building the ship.
The system specifics being as below:-
Tube Material ÔÇô Al-Brass
Tube Size ÔÇô 44.5 mm x 2 mm
Working Temperature ÔÇô Max 168 Deg C
Working Pressure ÔÇô 7 bar
The customers requirement were as follows :-

  1. To be able to repair the ships piping with NO Hot Work
  2. Avoiding the need of any fire watch
  3. To reduce on-site time and labour
  4. Work to be done with the involvement of the ships crew
  5. To achieve a safe, reliable and permanent leak free connection
