Anand Seamless Tubes Pvt. Ltd.

Mithakhali, Ahmedabad, Gujarat

Air preheater tubes are made from Cold Drawing process and are generally of Carbon Steel material. The application of these tubes is in an area where the tubes is not subjected to extremely high temperatures and pressures. Hence, the use of Carbon Steel tubes in applications for Air Preheater Tubes is generally preferable. There are various types of Air Preheaters; one of them widely used is Tubular Type Air Preheater. In this type of Air Preheater, straight tube bundles are used, which pass through the outlet ducting of the boiler and open at each end outside of the ducting, The hot furnace gases pass around the air preheater tubes, transferring heat from the exhaust gas to the air inside the preheater. Ambient air is forced by a fan through ducting at one end of the air preheater tubes and at other end the heated air from inside of the tubes emerges into another set of ducting, which carries it to the boiler furnace for combustion.

Seamless PIPES mainly find applications inPressure Piping, Cryogenic Pressure Vessels and piping, High pressure Equipments, heat exchanger tubes, Boilers, Air Pre Heater, Air Cooler Tubes, Steam Release Pipes, Steam trap piping etc. They are used in Industries like Refineries, Power Plants, Steel Plants, Chemical Factories, Fertilizer plants, and Ship Building etc.

Seamless Pipes can be manufactured in Straight Lengths of Single Random Length, Double Random Length or Fixed Length.

OurSeamless Tubesare manufactured by the Cold Drawn Process (Drawn on Mandrel) to provide the closest dimensional tolerance and smooth Outside and Inside Finish. Further to achieve the desired Mechanical Properties the tubes are Heat Treated ( Normalized , Stress Relieved , Annealed , Tempered Etc ) as per the Customer / Grade requirement. Straightening is done on Multiple Roll Straightening Machines to achieve accuracy up 1mm: 1000mm Straightness. Our stringent Quality checks and Best Packing practices (For Exports Special 4 Layer Packing) ensure that the material delivered to the customer is of the highest quality and reaches the destination in best condition.

We manufacture these tubes as per various international standards such as :

	ASTM A 53 GR A/ ASME SA 53 GR A		ASTM A 53 GR B/ASME SA 53 GR B
	ASTM A 106 GR A/ASME SA 106 GR A		ASTM A 106 GR B/ ASME SA 106 GR B
	ASTM A 106 GR C/ ASME SA 106 GR C		ASTM A 213/ ASME SA 213 ( P2, P5, P11, P12, P22 etc)
	ASTM A 333 GR 1/ ASME SA 334 GR 1 ( LOW TEMPERATURE APPLICATION)		ASTM A 333 GR 3 / ASME SA 334 GR 3 ( LOW TEMPERATURE APPLICATION)
	ASTM A 333 GR 6 / ASME SA 334 GR 6 ( LOW TEMPERATURE APPLICATION)		ASTM A 333 GR 7 / ASME SA 334 GR 7 ( LOW TEMPERATURE APPLICATION)
