Sunny Enterprises, a one of the former O.D. Outer Diameter Pipe Manufacturers, Suppliers and Exporters in India. We provide the proper outer diameter piping which is essential for the various types of applications that can provides the standardized way to measurement.

The outer diameter piping is more useful for the accurate fittings and ensures that pipes, fittings, flanges from different manufacturers can fit together correctly. It allows for interchangeability in between the different piping systems and it also keeps the consistency across different pipe schedules. Below, we have briefly mentioned the types of our outer diameter piping, its benefits and applications also!

Our multiple types of Outer Diameter Piping

As a former outer diameter piping manufacturers, suppliers and exporter in India, we provide multiple types of outer diameter for different types of pipes such as:

  • Nominal Pipe Size (NPS) - North America (ANSI/ASME B36.10 & B36.19): In these outer diameter piping, we provides commonly sizes such as ½", ¾", 1", 2", 4", 6", 8", 10", 12", 16", 24", etc. and schedules: Sch 5, Sch 10, Sch 40, Sch 80, Sch 160, Sch XXS. The outer diameter in these piping remains constant and wall thickness (Schedule) can varies. It is specifically used in the steel, stainless steel and other metal pipes also.
  • Tubing (OD-based): We provide the sizes in these tubing such as ¼", ⅜", ½", ¾", 1", 1½", 2", etc. These sizes are measured by outer diameter and wall thickness and we use pure form of materials such as aluminium, stainless steel and plastic (PEX, PVC). These are majorly used in the HVAC, plumbing and industrial applications.
  • Copper Piping (ASTM B88): The sizing in the outer diameter of copper piping is based on type K, L, M, and DWV and each with different wall thickness. The common OD sizes in copper piping are ⅜", ½", ⅝", ¾", ⅞", 1⅛", etc.. These are used for plumbing, refrigeration and HVAC also.
  • HDPE (High-Density Polyethylene) Pipes: In these HDPE pipes the size follows IPS (Iron Pipe Size) or DIPS (Ductile Iron Pipe Size) standards and comes size such as 1", 2", 4", 6", 8", 10", 12", etc. Due to its stronger structure and ability to resist higher thermal temperature, these are used in water and gas distribution.
  • PVC & CPVC Pipes (ASTM D1785, D2846): These PVC and CPVC pipes are available in both the schedule 40 and 80. The size of the OD matches steel pipe but has the different kind of wall thickness. These re used for plumbing, water supply and chemical handling services also.

Importance of Outer Diameter (OD) Piping

The outer diameter is an important factor in the manufacturing of piping and highly useful in the multiple applications such as industrial, commercial and residential sectors also. We briefly mentioned below the importance of our Outer Diameter piping services:

  • Standardization and compatibility: The pipes, flanges and valves are manufactured by the different types of companies and we offer our outer diameter for all types of pipes and ensure proper fittings to the applied applications. It comes with different organization as well such as ASME (American Society of Mechanical Engineers), ASTM (American Society for Testing and Materials), and ISO (International Organization for Standardization).
  • Consistency across Different Pipe Schedules: In our outer diameter piping, we gives higher consistency across different pipe schedules. In Nominal Pipe Size (NPS) systems the outer diameter remains constant and the wall thickness varies according to the pipe schedule (Sch 10, Sch 40, Sch 80, etc.). In these piping systems, the components such as valves and fittings fir perfectly without requiring modifications.
  • Essential for Pipe Fittings and Connections: Our all types of OD manufactured pipes are specially designed with standard fittings such as couplings, elbows, tees and reducers. We provide accurate OD measurement that are more secure and has leak-proof connections as well. These are highly used in the plumbing, oil & gas and fire protection industries also.
  • Precision in Tubing and Specialty Applications: In multiple types of applications such as medical gas lines, refrigerators and instrumentations, we provide higher accuracy in these applications and manufacture standard OD tubing sizes including ¼", ⅜", ½", ¾", 1", 1½", and 2". The stainless steel tubing is majorly used in food processing industries, pharmaceuticals and chemical industries also.

Benefits of our Outer Diameter (OD) Piping

Being the best outer diameter piping suppliers and exporters in India, our outer diameter piping services gives multiple types of benefits such as:

  • Standardized Sizing: Our OD pipes are manufactured to meet industry standards and ensure compatibility with various fittings and connections. This standardization allows for easy integration into new and existing piping systems.
  • Easy Measurement: We produce OD pipes with accurate dimensions that can be easily measured using standard tools like calipers or measuring tapes. This can simplifies the overall process and also reduces errors during installation.
  • Consistent Wall Thickness: Our advanced manufacturing processes ensure uniform wall thickness and this can be more beneficial for maintaining pressure rates and structural strength. This consistency enhances safety and performance in critical applications.
  • Better Flow Calculation: With accurate OD sizing, engineers can precisely calculate flow rates and pressure drops for optimal system efficiency. This leads to better fluid management, reducing energy costs and improving performance.
  • Enhanced Compatibility: Our OD piping is designed to work with a wide range of industry-standard components, including flanges, valves, and fittings. This ensures flexibility and ease of use across different industries and applications.
  • Improved Strength & Durability: Made from high-quality materials, our OD pipes are built to withstand extreme conditions, including high pressure and temperature variations. This makes them ideal for oil & gas, chemical processing, and industrial applications.

Frequently Asked Questions (FAQs)

OD refers to the external measurement of a pipe. It is crucial for determining pipe fittings and compatibility.

OD is the actual outer measurement, while NPS is a standard designation. NPS pipes may have varying wall thicknesses.

It ensures proper fitting, flow rate, and pressure handling. Many industries use OD for precise installation and compatibility.

Use a caliper or OD tape around the pipe. Ensure accurate measurement across the widest external point.
