Discover the factory capacity and outstanding production capacity of E.NHAT – Vietnam’s leading spiral welded steel pipe manufacturer with 4 production lines, US welding technology and a capacity of 180,000 tons/year.
1. Powerful factory scale with 4 production lines across 3 regions
E.NHAT Industrial Joint Stock Company is currently operating 4 spiral welded steel pipe production lines, located in strategic locations: Hung Yen, Vung Tau and Ninh Thuan. This is an advantage that helps E.NHAT Group optimize delivery time, save transportation costs and promptly meet construction needs across the country.
Each factory is invested with a synchronous and modern machinery system, ensuring strict quality control and maintaining high performance under all production conditions. With a total capacity of about 180,000 tons of spiral welded steel pipes per year, this network helps E.NHAT Group serve customers across the country – from North to South – with speed and smoothness in the supply chain.
2. Impressive capacity – 180,000 tons of spiral welded steel pipes per year
E.NHAT Group has the capacity to produce diameters from DN250 to DN4020mm, thicknesses from 5mm to 25mm, lengths up to 12 – 24m or as required. Some typical parameters:
- Maximum outer diameter: up to Ø4020mm
- Pipe length can reach more than 12m, even up to 24m if customer has special request.
- Diverse production according to international standards such as API5L, ASTM A252, JIS G3443…
The highlight is high productivity – more than 600 tons/day, allowing E.NHAT Group to quickly process huge orders while still ensuring progress.
3. Lincoln PowerWave Welder – Raising the bar for spiral welded steel pipe quality
E.NHAT Group is a pioneer in investing in the Lincoln PowerWave AC/DC 1000SD automatic welding system – technology from the United States, currently being installed synchronously in all factories.
Outstanding advantages of this welding system:
- Stable welding current, minimizes weld defects, improves product uniformity and durability.
- Multi-arc welding – allows multiple machines to operate in sync, dramatically increasing productivity.
- Optimized power thanks to power factor (PF) reaching 95%.
- Suitable for a wide range of steels and demanding technical requirements, from water supply to oil and gas projects.
- Withstands heavy industrial environments (IP23 protection standard), durable operation even in harsh outdoor conditions.
Thanks to the application of this advanced welding technology, E.NHAT spiral welded steel pipes always have tightness, tensile strength and pressure resistance exceeding standards, ensuring absolute reliability for large engineering projects.
4. Modern auxiliary machine system – Ensuring international technical standards
Besides the welding system, E.NHAT Group invests in many advanced auxiliary equipment:
✅ Closed shot blasting machine: cleans the pipe surface before and after welding, helps the paint adhere better, increases the service life and corrosion resistance.
✅ Steel pipe pressure testing machine up to 80 bar: each batch of pipes is strictly pressure tested before leaving the factory. This helps detect potential leaks or weaknesses, ensuring operational safety for the investor.
✅ Automatic pipe end lathe: helps to process the pipe end surface to be smooth, square, and according to technical standards before welding or flange installation. This device ensures tightness and precision when connecting pipe sections, especially important in water, oil and gas systems or high pressure projects.
These quality control systems not only help E.NHAT Group maintain high production standards, but also create absolute trust in demanding engineering contracts.
5. Export Capacity: Reaching International Markets
6. Typical projects implemented
Outstanding spiral welded steel pipe production capacity helps E.NHAT Group become a reliable partner in many large projects such as:
7. Technical team and many years of experience in the mechanical industry
