ASTM Specification |
Brief Explanation |
|
A-179 |
This specification covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. This specification covers tubes 1/8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter. |
|
A-214 |
This specification covers minimum-wall-thickness, electric-resistance-welded,carbon steel tubes to be used for heat exchangers, condensers, and similar heat-transfer apparatus. Covers tubes 1/2 in. to 5 in. O.D. and 0.035 in. to 0.320 in. minimum wall thickness. |
|
A-500 |
This specification covers cold-formed welded and seamless carbon steel round, square, rectangular, or special shape structural tubing for welded,riveted, or bolted construction of bridges and buildings, and for general structural purposes. |
|
A-513 |
This specification covers electric resistance welded carbon and alloy steel tubing for use as mechanical tubing. This specification covers mechanical tubing made from hot or cold rolled steel. This specification covers round, square, rectangular, and special shape tubing. |
|
A-519 |
This specification covers several grades of carbon and alloy steel seamless mechanical tubing. When welding is used for joining the weldable mechanical tube grades, the welding procedure shall be suitable for the grade, the condition of the components, and the intended service. |
Benefits of Custom Tube




1. Meeting personalised needs: Customised tubes can be produced according to customers' specific requirements to meet the personalised needs of different industries and scenarios. Special sizes of steel pipes, decorative pipes with specific colours, or industrial pipes with special shapes, etc. can all be realised through customisation.
2. Improve production efficiency: Customised production can improve production efficiency by reducing unnecessary waste and loss. Compared with standard products, customised pipes can be produced faster to meet customer requirements, which in turn improves overall production efficiency.
3. Reduced costs: Customised tubes can eliminate material waste and unnecessary processing costs, helping projects to achieve cost control. In addition, customised tubes can also reduce production processes and material waste, further reducing production costs.
4. Improved economic efficiency: Customised tubes can ultimately improve economic efficiency by meeting customer needs, increasing productivity and reducing costs. This flexibility gives companies a competitive edge in the marketplace.
5. Variety of choice: Customised services offer a wide choice of colours, sizes, shapes and surface finishes. Whether it's decorative or industrial piping, custom services offer a variety of options to meet the needs of different application scenarios.
6. High strength and crush resistance: Customised tubing typically has high strength and compressive strength to ensure safety and stability in use. This feature makes customised pipes suitable for demanding applications such as water supply systems in high-rise buildings.
7. Corrosion resistance and durability: Customised pipes usually have good corrosion resistance and can be used for a long time in harsh environments. The service life of customised pipes is usually long, typically up to 70 years or more, reducing the frequency of pipe replacement and maintenance costs.
Types of Custom Tube
Non-Standard convex tubes:
These customised pipes can be tailored to meet actual requirements, with common diameters ranging from DN100 to DN2000, lengths from 1m to 10m and wall thicknesses from 2mm to 10mm. The diameters, lengths and wall thicknesses of non-standard convex tubes can be tailored to suit different fluid characteristics and applications.
PPR pipe:
PPR pipe is one of the most widely used plumbing materials in domestic installations today. It has the advantages of non-toxic, odourless, heat resistant, corrosion resistant, etc., can be used for a long time in a certain temperature range, and easy to install, high strength at the interface, not easy to leak problems.
It is easy to install, high strength at the joints and not easy to have leakage problems. However, PPR pipe has poor performance in low temperature environment and is not suitable for outdoor exposure environment.
PVC pipe:
PVC pipe is also widely used in home decoration, especially in the drainage system. It is cheap, chemically resistant and easy to install. However, PVC pipe has poor thermal stability and is not suitable for hot water transportation system, and it is easily deformed under high temperature.
Copper:
Copper is a high quality pipe with excellent performance. It has excellent antimicrobial properties that inhibit bacterial growth and reproduction, and is suitable for water supply systems in high-end residential and commercial buildings.
Application of Custom Tube
Machining:
Customised tubing is used in machining to connect and transport a variety of fluids and gases, and to meet the specific requirements of machinery and equipment for piping.
Aeronautics:
The aviation field has very high requirements for piping, customised pipe can meet the installation needs of complex piping inside the aircraft to ensure flight safety.

Construction:
In construction, custom pipe is used in water supply, drainage, HVAC and other systems to ensure that the size and material of the pipe meets the specific needs of the building design.
Petrochemical:
In the petrochemical industry, customised pipes are used to transport a variety of chemicals and oil and gas, and are required to be corrosion resistant and have high pressure characteristics.
Production Process of Custom Tube
Demand analysis:
Customers define their own needs, including pipe size, colour, connection method, etc.
01
Programme design:
Suppliers according to customers' needs for programme design, choose the right material and determine the production process.
02
Manufacturing:
Strictly according to customer requirements to ensure product quality and delivery time.
03
Quality inspection:
Quality inspection after production is completed, including appearance inspection, size measurement, performance test, etc.
04
Delivery:
After passing the quality inspection, the supplier will deliver the products to the customers, and the customers will install and use the products according to the requirements.
