Important for successful Projects

Clad pipes offer an ideal solution for the most stringent prerequisites of quality, corrosion tolerance and cost efficiency. Here, the usually unalloyed carbon steel external pipe handles the inner and outer pressure, while the high-amalgam cladding gives the corrosion protection.

Crystal Industrial is at present the main pipe producer globally, delivering clad pipes by two diverse procedures. In addition to mechanically bonded pipes Crystal Industrial from India produces pipes from metallurgically clad steel plates in a discontinuous manufacturing process. In these purchased in sheets, the two metal layers are reinforced firmly together by a diffusion bridge.

Metallurgically clad pipes

The developing worldwide requirement for fuels is encountered by the oil and gas enterprises with the challenge of exploiting rising unavailable stores. These incorporate energy reserves under deep water, with media comprising destructive components at high temperatures and compressions. Due to these conditions, severe requests are placed on the corrosion tolerance of the pipework materials in which oil and gas are to be conveyed. For both technical and financial reasons, pressurized pipes are not made completely of stainless steels or nickel amalgams. Crystal Industrial from India has been working for a long time to join the corrosion tolerance of high-amalgam steels with the brilliant quality and flexibility attributes of carbon manganese steels by creating clad steels.

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

The pipes delivered by Crystal Industrial from clad materials are utilized internationally for a wide range of applications, for the most part in the oil and gas enterprises. A key utilization of clad pipes in this organization is for riser pipes. While pipelines are laid evenly on the ocean bed, the term riser covers those pipes that are responsible for conveying the medium vertically from the ocean bed to the surface for additional processing.

Due to the way they are suspended from the floating generation, storage and off loading vessel, and the strategy for laying them to the removal point on the ocean bed, these pipes are presented to large powerful stresses from the streams and the movement of the ship, both on a level plane and vertically.

Individual Material Combinations

The primary parent metals utilized for clad plates are basic steels, pipe steels (API evaluations) and fine-grained structural steels recognized by a nice weldabilty and working characteristics. The selection is made after testing the quality and durability necessities for the particular working conditions. Ordinary cladding materials are austenitic stainless steels, nickel and copper nickel and titanium amalgams, featured by various levels of corrosion tolerance.

The high inward and outward pressure from sea flows and wave movements, and extremely destructive media, imply that these pipes need to fulfill the most stringent quality measures. The outcoming form resistances and welding necessities constitute a continuous challenge to Crystal Industrial in the manufacture of these pipes.

In remote oceanic regions Crystal Industrial’s unique pipes are utilized, which are under considerable dynamic stress as well as high compression and temperature, thus additionally require particularly high imperviousness to stress. For this, the most firm resistances and specific quality measures need to be met in the manufacture of the welded connections and pipe ends.

Crystal Industrial’s Line pipe solutions for harmful conditions

For seaward and marine pipelines that require to maintain a harmony between the mechanical characteristics of the C-Mn tube steel and the corrosion protection qualities of a Corrosion Resistant Alloy (CRA) Crystal Industrial from India gives clad and lined pipes.

Production liquids commonly include a high sulfur or CO2 content that needs the use of materials appropriate for destructive conditions. Right when the H2S and CO2 content increase for the corrosion protection characteristics of C-Mn steel, a CRA is routinely utilized.

Crystal Industrial’s Solid CRA, Clad and Lined Pipes

For clad pipes, the layer of Corrosion Resistant Alloy (CRA) is connected utilizing diverse methods that make a metallurgical bond, while the lined pipe is connected through a mechanical bond among the CRA and the C-Mn pipe.

Both clad or lined pipes incorporate a C-Mn pipe which has a layer of CRA in contact with the generated liquid and subsequently its ruinous condition. As a result of clad pipes, the layer of CRA is attached utilizing diverse methods that make a metallurgical bond, as in case of lined pipe an inward CRA pipe is attached with the outside C-Mn pipe through mechanical bond.

Crystal Industrial from India has been converting clad materials into pipes and piping parts since many years. By utilizing clad materials, the improved quality and toughness of carbon-manganese steels are connected with the corrosion tolerance of high-alloyed materials. The use of clad pipes is suggested in all regions where dynamic stress, high compression and a raised level of danger can be found in the media transmitted. Pipes made using clad materials comply with the most stringent necessities of sturdiness, corrosion resistance and great value.

By utilizing clad materials, the exceptional quality and sturdiness of carbon-manganese steels are attached with the corrosion tolerance of high-alloyed materials. Crystal Industrial from India has been delivering clad pipes and pipage parts for around 20 years. Reputed clients utilize our cladded products since a long time. Crystal Industrial from India is the primary pipe producer internationally that produces both longitudinally welded metallurgically clad and mechanically lined pipes. Crystal Industrial from India in addition changes over clad pipes into ready-to-introduce spools.

Metallurgically clad pipes give the benefit of small wall thicknesses in comparison with austenitic strong wall pipes and solid wall pipes produced using nickel-based amalgams. Different advantages incorporate crucial weight savings and decreased material expenses. Metallurgically clad pipes are utilized, for instance, as riser or process pipes, pipage or pipes for elbows and connections. Other application regions can be given on demand.

The manufacturing procedure

Clad plates are utilized as crude material for the production of metallurgically clad pipes. The plates include a base material and a corrosion tolerant amalgam material. They are attached together tightly by a diffusion bridge.The plates are produced individually on a press brake, utilizing the exceptional method, into an open seam pipe and furnished with a longitudinal weld by various typical welding systems. We can additionally give thermal treatment to the clad pipes after the welding procedure, relying upon the planned use.

Within quality confirmation, typical non-hurting tests can be carried out on the finished pipe: shading penetrant, magnetic molecule, ultrasonic, X-bar, measurements test besides, a trial of the rest of the magnetism can be done.

Crystal Industrial’s clad pipes from India have been utilized productively in the onshore and marine areas of the oil and gas enterprises since a long time. Ordinary applications are pipes or riser pipes; they are additionally established as SCR pipes. Various areas of utilization are acquirable on demand.
