Crystal Industrial’s Metallurgically clad pipes from India

As of now since long time Crystal Industrial from India has been manufacturing pipes from metallurgically clad plates for esteemed international clients. The tight attachment between the metal layers of these pipes is accomplished by a diffusion bridge. Contingent upon their intended application and technological necessities metallurgically clad pipes are utilized, for instance, as riser pipes, process or line pipes.

Technological specifications:

• Sizes range OD 114,3 (4″) up to 1 219 mm (48″).
• Surface thicknesses up to 70 mm.
• Highest wall thickness/OD proportion 1:10.
• Ergodic lengths up to 24 m (6 m and 12 m lengths without circumferential weld).
• Appropriate for S-Lay and J-Lay technique, bundle or reel-lay process.

Benefits of metallurgically clad pipes:

• Decrease in wall thickness.
• Benefits in terms of expense already in case of little measurements versus full-wall pipes.
• Decrease in weight.
• Wide range of material blends possible.

Crystal Industrial’s Clad pipes for the oil and gas industry

Crystal Industrial has the capacity to exhibit its core competency in welding, shaping and materials technology with a wide range of pipes for coastal and seaward ventures and subsea applications. We create for you flowlines, riser pipes and others for topsides and also line pipes. You may utilize the financial advantages of both our mechanically lined pipe and the metallurgically clad pipe: Reliability and life span by corrosion protection. The unalloyed external pipe controls the compression, while the high-alloyed cladding assures corrosion resistance.

Key to Successful Projects

Crystal Industrial’s Clad pipes from India provide an ideal solution for the most stringent necessities of toughness, corrosion protection also, cost – efficiency. Here, the (usually) unalloyed carbon steel external pipe handles the inner and outer compression, while the high-amalgam cladding gives the corrosion resistance.

Crystal Industrial from India states that they are presently the main pipe producer globally creating clad pipes by two distinctive procedures. Additionally, mechanically reinforced pipes, the pipe maker of India manufactures pipes from metallurgically clad steel plates in an irregular manufacturing process. In these bought-in sheets, the two layers of metal are reinforced tightly together by a diffusion bridge.

Crystal Industrial from India essentially handles roll-bonded crude material, yet in addition utilizes explosive fortified plates in particular cases. As per the necessities and descriptions pipes are created from single plates of different material grade mixes. The cladding can be connected on one side – outside or inside – or the two sides.

Individual Material mixtures

The primary parent metals utilized for clad plates are constructive steels, pipe steels (API grades) and fine-grained constructive steels recognized by a good weldabilty and operating attributes. The selection is made after monitoring the toughness and malleability prerequisites for the specific working conditions.

Common cladding materials are austenitic stainless steels, nickel and copper nickel and titanium amalgams, featured by various levels of corrosion tolerance.

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.
