Best Price ASTM Carbon Steel Pipe X42 Welded Steel Tubes and Pipes Spiral Steel Pipe

Product Overview

The Production Process of Spiral Welded Pipe Mainly Includes The Following Steps:

Raw material preparation: low carbon steel or low alloy steel strip is used as raw material.

Coiling and forming: the steel strip is coiled into a spiral shape through a series of rollers.

Welding: Double-sided submerged arc welding technology is used to ensure the strength and continuity of the weld.

Quality control: Non-destructive testing by means of ultrasonic flaw detection and X-ray inspection.

Surface treatment: Anti-corrosion treatment, such as galvanising and painting, is carried out according to requirements.

Uses:

Oil and gas industry: used to transport oil, natural gas and other fluids.

Construction and infrastructure: as support material for bridges, roads, building structures.

Chemical & Electric Power: Used for conveying chemical medium, cooling water, steam, etc.

Agricultural irrigation: used in farmland irrigation system.

Automobile manufacturing: used in automobile exhaust system, cooling system.

How We Deliver Best-Price Value

• Mill-Direct Coil & Plate Sourcing: We purchase HR coils and heavy plates in rolling-mill quantities, locking in base steel prices before market volatility affects spot buyers.
• Process-Matched Production: We route your order to the most cost-efficient welding line—ERW for standard sizes, LSAW for thick-wall large pipe, SSAW for maximum diameter economy—ensuring you do not overpay for unnecessary process sophistication.
• Simplified Specification Options: PSL1 chemistry offers significant savings over PSL2 for non-sour, non-critical services. We help you select the correct PSL level to avoid over-specification.
• Bulk Logistics Optimization: Full truckload (FTL), full container load (FCL), and bulk vessel shipments are containerized or nested to minimize freight cost per meter.
• Flexible Commercial Terms: Competitive pricing for spot orders; additional discounts for quarterly or annual offtake agreements with scheduled releases.

FAQ

Q:What is your MOQ and delivery time?

A:The MOQ is flexible and depends on diameter and wall thickness — for many sizes we can start from small trial orders. Standard production usually takes 15–30 days after deposit; stock items can ship within days. Please confirm your specification for an accurate lead time.

Q:How is the price calculated?

A:The price is based on steel grade, size, wall thickness, length, quantity, surface treatment and current raw material cost. Please send us your detailed requirement and we will reply with a best-price quotation, typically on FOB, CIF or CFR terms.

Q:Do you provide samples before ordering?

A:Yes. Small samples can be provided for evaluation. The sample cost is usually refundable or deducted from the bulk order, depending on the product and quantity.

Q:Which payment terms do you accept?

A:We accept T/T (30% deposit, 70% before shipment or against B/L copy), L/C at sight, and other terms that can be negotiated for larger or regular orders.

Q:Is your company a manufacturer or a trading company?

A:We are a manufacturer with our own production lines for ERW, LSAW and spiral welded pipes, which allows us to offer competitive factory-direct pricing, consistent quality control and direct after-sales support.
