Turbo Chill Tubes is an integral low fin tube provided with spiral ridges on the inside. In a Turbo Chill Tube, the inside fluid heat transfer capability is remarkably improved in comparison with the smooth in-tube type tubes. By the effects multiplied mutually by the tubes outside fins and inside spiral ridges a high coefficient for overall heat transfer is obtained. These parameters significantly contribute to the reduction in size of various freezing machines. Normally, Turbo Chill Tubes are generally supplied with 8 & 10 starts configuration; however, it can also be fabricated with other number of starts on request. These tubes are fabricated in alloy C 12200 to meet the chemical, mechanical and other test parameters of ASTM B 75 / B 359 and in alloy 70600 to meet the chemical, mechanical and other test parameters of ASTM B 111 / B 359. BS EN, JIS and DIN standards are also available on request. For tube parameters of 22.2 mm, 25.4 mm tube or any other special requirements please contact us. Turbo Chill tubes with fin density other than mentioned in the above chart can be produced on request. Turbo Chill Tubes with alloy 71500 is also available; please contact us for Fin parameters. Turbo Chill Tubes are generally supplied in the “as finned” condition. However, alloy 70600 & 71500 can be supplied in “annealed” temper upon specific request.

Precise design and unfailing functionality are the defining attributes of the Cupro Nickel Weld Neck Flanges offered by us. We are enlisted amid the premier Manufacturers, Suppliers and Exporters of the Welding Neck Cupronickel Flanges in India and abroad. Our quality controllers fastidiously check these Flanges to assure 100% compliant quality. Avail them from us at competitive rates.More About Cupro Nickel Weld Neck Flanges :Welding Neck Cupronickel Flanges OR Copper nickel Flanges are easy to recognize at the long tapered hub, which goes gradually over to the wall thickness from a pipe or fitting. The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures. The smooth transition from flange thickness to pipe or fitting wall thickness affected by the taper is extremely beneficial, under conditions of repeated bending, caused by line expansion or other variable forces. These Cupronickel flanges OR Copper nickel Flanges are bored to match the inside diameter of the mating pipe or fitting so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion. They also provide excellent stress distribution through the tapered hub and are easily radio-graphed for flaw detection.

Available in wide range of specifications, these Threaded Cupronickel Flanges are innovatively designed to render hassle free functions to the clients. After quality assurance, these Flanges are enclosed in tamper-proof packaging. Get them from us in desired quantity at unbeatable prices.More About Cupro Nickel Threaded Flanges :Threaded Cupronickel Flanges OR Copper nickel Flanges are used for special circumstances with their main advantage being that they can be attached to the pipe without welding. Sometimes a seal weld is also used in conjunction with the threaded connection. A threaded flange is not suitable for a pipe system with thin wall thickness, because cutting thread on a pipe is not possible. Thus, thicker wall thickness must be chosen for such type of Cupro Nickel Flange.

We put at the disposal of global clients, the Cupro Nickel Socket Weld Flanges that are made in conformity with the industry laid standards. We gratify our clients by offering these Socket Weld Cupronickel Flanges in plenty of specifications. Also, we guarantee the durability and optimal performance of these Flanges. As a reputed Manufacturer, Supplier and Exporter, these Flanges are offered by us at fair-market prices.More About Cupro Nickel Socket Weld Flanges :Socket Weld Cupronickel Flanges OR Copper nickel Flanges were initially developed for use on small-size high pressure piping. Their static strength is equal to Slip On flanges, but their fatigue strength 50% greater than double-welded Slip On flanges. The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe. ASME B31.1 1998 127.3 Preparation for Welding (E) Socket Weld Assembly says :In assembly of the joint before welding, the pipe or tube shall be inserted into the socket to the maximum depth and then withdrawn approximately 1/16" (1.6 mm) away from contact between the end of the pipe and the shoulder of the socket. The purpose for the bottoming clearance in a Socket Weld is usually to reduce the residual stress at the root of the weld that could occur during solidification of the weld metal.

Based in Mumbai, we have carved a niche in the global markets as the honorable Manufacturer, Exporter and Supplier of the superlative-quality Cupro Nickel Slip On Flanges. Our Slip On Cupronickel Flanges are contrived using the up-to-the-minute technology by our profound engineers. We facilitate the buyers by offering ample specifications of these Flanges at rock-bottom prices.More About Cupro Nickel Slip On Flanges :The calculated strength from a Slip On Cupronickel Flange OR Slip On Copper nickel Flanges under internal pressure is of the order of two-thirds that of Welding Neck flanges, and their life under fatigue is about one-third that of the latter. The connection with the pipe is done with 2 fillet welds, as well at the outside as also at the inside of the flange. The X measure on the image, are approximately Wall thickness of pipe + 3 mm. This space is necessary, to do not damage the flange face, during the welding process. A disadvantage of the flange is, that principle always firstly a pipe must be welded and then just a fitting.

Durability, neat finishing, rugged construction, and corrosion resistance are the USP of our Cupro Nickel Lap Joint Flanges. We build them in varying specifications to make them fit various industrial requirements sufficiently. Quality assured in impeccable way, these Flanges are obtainable at the market-leading prices. We are the illustrious Lap Joint Cupronickel Flanges Manufacturer, Supplier and Exporter in India and abroad.More About Cupro Nickel Lap Joint Flanges :Lap Joint Cupronickel Flanges OR Copper nickel Flanges have all the same common dimensions as any other flange however it does not have a raised face, they are used in conjunction with a "Lap Joint Stub End". These flanges are nearly identical to a Slip On flange with the exception of a radius at the intersection of the flange face and the bore to accommodate the flanged portion of the Stub End. Their pressure-holding ability is little, if any, better than that of Slip On flanges and the fatigue life for the assembly is only one tenth that of Welding Neck flanges. They may be used at all pressures and are available in a full size range. These flanges slip over the pipe, and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe lap (Stub End).

Avail from us the Cupro Nickel Blind Flanges in spectrum of sizes and designs to ensure the hassle-free service for lifetime. We are among the noteworthy Manufacturer, Supplier and Exporter of the Blind Cupronickel Flanges in India and abroad. Resistant and durable in nature, these Flanges are accessible at budget-friendly prices.More About Cupro Nickel Blind Flanges :Blind Cupronickel Flanges OR Copper nickel Flanges are manufactured without a bore and used to blank off the ends of piping, Valves and pressure vessel openings. From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed flange types. However, most of these stresses are bending types near the center, and since there is no standard inside diameter, these Cupronickel flanges OR Copper nickel Flanges are suitable for higher pressure temperature applications.
