Seamless Fluid Pipes

1. Raw Material Preparation: 

Selection of high-quality steel billets (carbon/alloy/stainless/special alloys) based on application requirements.

2. Piercing: 

Heating steel billets to high temperatures and piercing to form a hollow shell using a mandrel mill.

3. Rolling: 

Precision rolling of the hollow shell to achieve desired outer diameter and wall thickness, ensuring dimensional accuracy.

4. Sizing & Straightening: 

Calibrating the pipe to meet strict tolerance standards, followed by straightening for easy installation.

5. Heat Treatment: 

Annealing, quenching, or tempering to enhance strength, toughness, and corrosion resistance—critical for alloy and stainless steel variants.

6. Surface Treatment: 

Pickling, passivation (for stainless steel), or anti-corrosion coating to withstand harsh regional conditions.

7. Testing & Inspection: 

Hydrostatic pressure testing, ultrasonic (UT) testing, and chemical composition analysis to verify leak-proof performance and compliance.

8. Packaging: 

Preparation for global shipping with protective materials.

Leak-Proof Reliability: 

No welded seams eliminate failure risks, critical for high-pressure fluid transport in Qatar’s oil&gas and Nigeria’s chemical industries.

High Pressure & Temperature Resistance: 

Withstands extreme pressure and temperatures (-50°C to 600°C), suitable for Iran’s power plants and Turkey’s industrial systems.

Corrosion Resistance: 

Stainless steel/special alloy variants resist coastal humidity (Tanzania/Kenya), chemical erosion (Nigeria/Iran), and desert dust (Qatar/Iraq).

Smooth Inner Surface: 

Minimizes fluid friction and scaling, ensuring efficient flow for Kenya’s water supply and Iraq’s irrigation systems.

Durable & Long-Lasting: 

Robust construction adapts to varied climates, reducing maintenance costs across target regions.

Versatile Compatibility: 

Suitable for oil&gas, chemicals, steam, and water—meeting the diverse needs of Qatar’s energy, Tanzania’s infrastructure, and Turkey’s manufacturing.

Our Seamless Fluid Pipes comply with international and regional standards for global project approval:

RFQ Question: Do your seamless pipes resist Qatar’s desert heat for oil&gas pipelines? 

Answer: Yes, our API 5L Gr. B seamless pipes withstand 55°C+ desert heat and high pressure. Delivery takes 15-20 working days to Qatar.

RFQ Question: Can you supply high-pressure seamless pipes for Nigeria’s chemical plants? Delivery in 20 days possible?

Answer: Yes, our duplex alloy seamless pipes (ASTM A312) are ideal for Nigeria’s chemical industry—high-pressure and corrosion-resistant. 20-day delivery is guaranteed.

RFQ Question: What’s the warranty for seamless pipes used in Iran’s power plant steam lines?

Answer: Our ASTM A335 P22 alloy pipes come with a 5-year warranty for Iran’s high-temperature steam lines. They meet ISIRI standards, deliver in 18-25 working days with bilingual documents.

RFQ Question: Are your pipes compatible with Turkey’s industrial hydraulic systems? Are they easy to install?

Answer: Yes, our ASTM A106 Gr. B seamless pipes suit Turkey’s hydraulic systems—leak-proof and easy to fabricate. They meet CE/PED standards with installation guides.

RFQ Question: Can your seamless pipes handle Iraq’s temperature fluctuations for water supply?

Answer: Our API 5L Gr. B pipes adapt to Iraq’s extreme temperatures (-10°C to 50°C) for water supply. They’re durable and corrosion-resistant with custom length options.
