Pipes and tubes are cylindrical hollow structures used primarily for conveying fluids, gases, or solids. While the terms "pipes" and "tubes" are often used interchangeably, there are slight differences between them. Pipes are generally used for conveying fluids and gases, while tubes are more often used in structural applications or for conveying fluids under pressure. Here's an overview of each aspect you asked about:
Common Materials:
Stainless Steel: Stainless steel pipes and tubes are popular due to their corrosion resistance, durability, and ability to withstand high temperatures. They are used in industries such as oil and gas, chemical processing, food processing, and construction.
Nickel Alloys: Nickel alloys offer excellent resistance to corrosion, high temperatures, and stress. They are commonly used in chemical processing, aerospace, marine, and power generation industries.
Copper Alloys: Copper and its alloys are known for their excellent thermal and electrical conductivity, corrosion resistance, and malleability. They find applications in plumbing, HVAC systems, electrical wiring, and heat exchangers.
Aluminium Alloys: Aluminium alloys are lightweight, corrosion-resistant, and have good thermal conductivity. They are used in applications where weight is a concern, such as automotive, aerospace, and construction industries.
Titanium Alloy: Titanium alloys offer a high strength-to-weight ratio, excellent corrosion resistance, and biocompatibility. They are commonly used in aerospace, medical implants, chemical processing, and marine applications.

Manufacturing Process Of Pipes & Tubes
Rolling and Welding
The strips pass through the number of rollers as per the required size. In the tubes-mill, the strip is gradually converted into the tubular shape. The fitted welding machine is then used to weld trim edges of the strip using TIG welding process.
Length Cutting
Rolled pipes and tubes thus manufactured are cut to the required lengths depending upon the industrial demand. We use a variety of methods—sawing, lathe cutting, rotary cutting, supported shear cutting, dual-blade shear cutting, and laser cutting.
Cleaning and Heating Phase
Subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes. Heat treatment is given on the continuously rolling hearth furnace.
Cold Drawing Process
Required size may not be obtained from the mill directly. Then, the cold operation process can be used to obtain the desired size. In the cold drawing process, the tube or pipe is drawn over the bench using Die plugs.
Finishing Process
Pipe and tubes are then subjected to cleaning, heat treatment, pickling and straightening. The computerized ink jet marking machine then mark the finished pipes or tubes. Then they marked with grade of material, size, heat number.
Features of Pipes and Tubes:
Corrosion Resistance: Many of these
materials offer excellent resistance to corrosion, making
them suitable for use in harsh environments.
Strength: Depending on the alloy and
manufacturing process, pipes and tubes can be engineered
to withstand high pressures and temperatures.
Ductility and Formability: Some materials
like copper and aluminium alloys are highly ductile and
easily formable, allowing for intricate shapes and
designs.
Conductivity: Copper and some other
alloys offer excellent thermal and electrical
conductivity, making them suitable for applications
requiring heat transfer or electrical conduction.
Applications of Pipes and Tubes:
Oil and Gas Industry: Pipes and tubes are used for
transporting oil, natural gas, and other fluids in
exploration, production, and refining processes.
Chemical Processing: They are used for conveying various
chemicals in chemical plants and refineries.
Construction: Pipes and tubes are used in plumbing, HVAC
systems, structural supports, and architectural
elements.
Aerospace: They are used in aircraft structures, hydraulic
systems, and fuel lines.
Automotive: Tubes are used in exhaust systems, fuel lines,
and structural components.
Medical: Tubes made from certain alloys like titanium are
used in medical implants and surgical instruments.
Advantages of Pipes and Tubes:
Durability: Many of these materials offer
high durability and longevity, reducing maintenance and
replacement costs.
Corrosion Resistance: The
corrosion-resistant properties of materials like stainless
steel and nickel alloys make them suitable for use in
corrosive environments.
Temperature Resistance: Some alloys, such
as titanium, can withstand extreme temperatures, expanding
their range of applications.
Lightweight: Aluminium and titanium
alloys are lightweight, making them suitable for
applications where weight is a concern, such as aerospace
and automotive industries.
Conductivity: Copper alloys offer
excellent thermal and electrical conductivity, making them
suitable for heat exchangers and electrical applications.
