Which manufacturing method is good for a durable joint? Know more about submerged arc welded pipes stock sizes, wall thickness and export packaging

Welding is a trustworthy manufacturing technique to produce durable joints with long service life. It involves joining parts by applying heat, pressure, and, occasionally, a filler material.

Low-pressure applications frequently use submerged arc welding or SAW. Here, SAW pipes can get manufactured as longitudinal and spiral. The approach creates high current density and lets the flux get concentrated for the welding area.
Dinesh Tube India can supply SAW pipes in different dimensions per user requirements. The standard diameters range from 16 inches to 60 inches. The wall thickness can vary from 1.6mm to 25mm. The company employs reliable export packaging to ensure prompt and damage-free delivery.

Top 6 reasons to choose carbon steel saw pipes

Several industries, like petrochemicals, oil & gas, mining, and paper & pulp, employ submerged arc welded pipes.

1. High welding quality: These pipes require lower labour effort than manual welding and also eliminate the need for arc radiation. The products have a smooth and uniform weld finish.
2. Good mechanical properties: Carbon steel pipes are sturdy, shock- and fire-resistant, and suitable for different connection types.
3. Affordable prices: Production efficiency and high productivity bring down the cost of carbon steel SAW pipes.
4. Corrosion and weather resistance: These pipes can handle trying temperatures, pressures, and abrasive agents.
5. Straightforward maintenance: The durability of these pipes reduces maintenance costs and efforts.
6. Direct installation and customization: The light, flexible nature streamlines installation, transport, and availability in different sizing.

What can be the maximum size and wall thickness? Why we can offer you the most competitive price: read these 4 reasons.

SAW pipes are available in different sizes based on industry requirements. The maximum size range is from 20 inches to 100 inches. Customers can use LSAW or seamless pipes ranging from 16” to 24”. However, they are the standard choice for large diameter pipes and piping over 24 inches.

Dinesh Tube can offer you competitive rates for your material needs. The company has:

1. A vast product portfolio to fulfil client needs on time
2. Associations with many manufacturers for high-quality products suitable for exports
3. Reliance on Japanese techniques like kanban and pokayoke for efficient and accurate production
4. Competent expert teams devoted to newer technologies for production and supply

Why are Magnetic Particle Inspection (MPI) & Ultrasonic Testing important?

Non destructive testing (or NDT) is a common approach to assess the quality of carbon steel saw pipes and identify defects and flaws in the internal structure. This testing is critical to rule out defective products that can affect the performance and safety of your application.
Magnetic particle inspection (or MPI) is an inexpensive, portable, and accurate technique under NDT. It builds a magnetic field around the product and coats it with iron particles. The induced current can help identify any flaws. However, it is not effective at recognizing defects under the surface.
Contrastingly, ultrasonic testing (or UT) uses a transducer to bring high-frequency waves into the product. The resulting 3D image reveals defects like cracks, fissures, etc. Various kinds of UT include phased array, straight beam, guided wave, etc. It is a quick and trustworthy method for different types of materials.

What should a buyer compare between ASTM A106 Gr.B and API 5l saw pipes?

Both these piping specifications get commonly used in industrial applications. Here are the criteria to help you choose:

• Manufacturing method: The ASTM A106 standard applies to seamless carbon steel pipes. However, API 5L refers to both seamless and welded steel pipes.
• Composition: An API 5l saw pipe requires a lower carbon content than ASTM A106 (0.28% instead of 0.30%). The chromium and manganese content is higher.
• Strength: API 5L is considerably stronger for oil and gas industries.
• Pressure rating: ASTM A106 seamless pipes can handle higher pressures.
• Cost difference: Seamless pipes, i.e., ASTM A106, are pricier than welded steel pipes.
