Crystal Industrial’s Mechanically lined pipes from India
The mechanically lined pipe was established by Crystal Industrial from India as a market development.
In comparison to a relatively strong wall version, the utilization of mechanically lined pipes can save 25– 50 % of expenses. Due to the production procedure and the crude material utilized, it is financially better than the metallurgically clad pipe.
Another benefit is the extensive variety of materials that can be chosen for both inward and external pipe. Highly variable consolidations of the relating materials are possible.
For a long time, Crystal Industrial’s Mechanically lined pipes from India have been utilized effectively in the inland and seaward zones of the oil and gas enterprises. Regular applications are pipelines or riser pipes; they are likewise set up as SCR pipes. Different regions of utilization are obtainable on demand.
Up till now, Crystal Industrial has manufactured more than 900 km of mechanically lined pipes for various ventures. Our production capabilities enable the manufacture of
between 14.5 to 20 km of pipes every month in sizes of between 4″ and 26″.
Manufacture process
In the hydro forming procedure we built up, a corrosion safe pipe is lined into a pipe of high quality carbon-manganese steel and extended with the assistance of a hydro forming press. The hydraulic extension process offers the benefit of even pressure dispersion without harming the pipe surface.
While further handling, weld cladding is connected to the Crystal Industrial’s Mechanically lined pipes so as to fabricate metallurgically clad pipe endpoints.
Sizes go from OD 114.3 (4″) to OD 660 mm (26″). Different sizes, even other than the standardized, can be created by agreement. We produce lengths of up to 12.2 m, any lengths past this up to 24 m are accomplished through circumferential welding. Crystal Industrial’s Mechanically lined pipes are appropriate for an extensive variety of laying procedures and in addition the reeling technique.
Use as riser pipes
In the oil and gas enterprises, clad pipes have been utilized as riser pipes and in addition steel catenary risers (SCR), among different things.
The riser pipes created for use in remote ocean regions are particularly presented to dynamic stresses and high temperatures. They should not be vulnerable to fatigue, must have great mechanical attributes and a high level of toughness and corrosion protection. At the point when creating these pipes, it is subsequently vital to follow the strictest resistances and extraordinary quality guidelines.
Crystal Industrial from India is the market pioneer in this area. We accomplish the strictest internal diameter resistances, including ovalness, of +/ – 0.25 mm. Hence, the movement of the pipe-endpoints is negligible, the welding on the development site is enhanced and the working life of the pipings rises.
The resistances are agreed as per current norms, e.g. API, ASTM, DNV or ISO, and much stricter resistance necessities have already been enforced for various Crystal Industrial ventures.
Ready-to-establish clad spools
Crystal Industrial from India forms clad pipes into spools ready to establish. For this we utilize semi-completed clad material for example, welded flanges, elbows, tees and reducers. Construction of clad pipes is utilized to optimize the piping quality and to decrease costs.
At a beginning phase in the manufacturing plant, the corrosion safe layer of the pipeline parts is pickled and passivated and all the non-ruinous tests are carried out.
This results in significant potential savings, particularly amid the consequent establishment of pipeline systems at the development site.
