COPPER TUBING & PIPES
Copper tubing is most often used for supply of hot and cold tap water, and as refrigerant line in HVAC systems. There are two basic types of copper tubing, soft copper and rigid copper. Copper tubing is joined using flare connection, compression connection, or solder. Copper offers a high level of corrosion resistance, but is becoming very costly.
Seamless and welded pipes
Seamless Pipes
Seamless pipes are in accordance with EEMUA–144, Section 1. They are manufactured from hot extruded shells followed by cold work and annealing.
Welded Pipes
Longitudinally welded pipes are in accordance with EEMUA–144, Section 2. They are manufactured from hot rolled or cold rolled and annealed sheet or plates in accordance with BS 2870, BS 2875, ASTM B171 or ASTM B402. Mechanical testing is carried out in accordance with the standards above. The pipes are supplied in “as welded” condition.
Ashtapad Overseas is a leading manufacturer of copper pipe fittings such as “Curpo Nickel Fittings (Cu-Ni Fittings)” also known as Copper Nickel C70600 (90/10) and C71500 (70/30) fittings in Mumbai, India. Ashtapad offers a complete range of copper pipe fittings such as Cupro Nickel reducer, Cupro Nickel elbow, Cupro Nickel tee, Cupro Nickel cross, Cupro Nickel stub ends and Cupro Nickel pipe bends.

Copper nickel is known for its strong general resistance to seawater. Due to high alloy concentration copper nickel fittings are widely used as connectors for piping systems in the ship building and power generation industry. ASHTAPAD is a leading exporter and supplier of copper nickel fittings (CUNI fittings) in Saudi Arabia, Qatar, Kuwait and other countries in the GCC region.
We also stocks and supplies a complete range of copper pipes to complement our existing production range of buttweld fittings and flanges. Copper pipes can be supplied in cut to length sizes and also machined or fabricated to meet your piping requirements.
Copper Nickel Pipes / Tubes / Copper Tubing Dimensional Range & Standard Specification
Dimensions
Dimensions are based on EEMUA –144, Tables 1.2.1-1.2.2 and 2.2.1-2.2.2. However, the pipe diameters range from ½ in./16 mm to 36 in./914 mm. Although the pipe dimensions of 38 in./965 mm and 40 in./1016 mm are not included in the EEMUA 144 – 1987 they are available on request as they are commonly specified. The corresponding wall thicknesses of the pipes comply with the pressure containment requirements of ASME B31.3 as well as the requirements of the International Association of Classification Societies. Pipes with other wall thicknesses are available on request.

Weld Preparation
For wall thickness less than 3 mm, the pipes are supplied with plain weld ends. Larger thicknesses are supplied with the weld bevel of 37 ½°±2 ½°.
Tolerances
-
The pipe sizes up to including 4 in./108 mm are based on BS 2871: Part 2: Table 3 for outside diameters and their tolerances to allow for the use of capillary and compression fittings and brazed (and welded) slip-on flanges. The wall thickness of the 16 bar range have been increased to match the 20 bar range for mechanical strength.
-
The pipe size 6 in./159 mm up to 16 in./419 mm are also based on BS 2871: Part 2: Table 3 for specified diameters but the tolerance have been applied to the inside diameters for facilitate alignment of matching weld preparations.
-
The ovality of the finished pipe doesn’t exceed 2% of the difference of the maximum and minimum diameter measured on the same cross section.
-
Up to including 4 in./108 mm, the wall thickness doesn’t vary by more than 10 % specified therein. For diameters from 6in./159 mm and larger, the wall thickness is not less than 12.5 % of the specified value.
The pipes with other dimensions than mentioned herein are available on request. Please contact us for more information.

Key Properties of Copper Nickel Pipes / Tubes / Copper Tubing Products
- Low corrosion in seawater/salt water applications
- High resistance to stress corrosion cracking (SCC) in seawater
- High general resistance to crevice corrosion and stress corrosion due to chlorides
- Strong pitting resistance
- Ease of welding and fabrication
Soft Copper Tubing
Project managers looking to bend soft copper tubing are likely searching for what is termed "annealed" tubing. Annealed tubing is far more malleable (or "bendable") than is drawn tubing. Malleable tubing is far easier to bend into shape and can survive rigorous forming operations.
