Product Detail

A106 Steel Pipe are steel pipes made of a single piece of metal with no seams on the surface, called seamless steel pipes. According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, and jacking pipes. According to the cross-sectional shape, seamless steel tubes are divided into two types: round and special-shaped, and special-shaped tubes have various complex shapes such as square, oval, triangular, hexagonal, melon-shaped, star-shaped, and finned tubes. The maximum diameter is up to 650mm and the minimum diameter is 0.3mm. Depending on the application, there are thick-walled tubes and thin-walled tubes. Seamless A36 Steel Pipe are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

Packing and Transportation

Standard Export Packaging

All steel pipes are firmly bundled with steel strapping and wrapped with professional waterproof materials. This standard export packaging effectively safeguards the pipes from surface damage, moisture and abrasion during loading, unloading and long-distance transit.

Pipe End Protection

To avoid end deformation, impact damage, dust and moisture contamination, we equip each pipe end with durable plastic or metal protective caps, keeping the pipe interiors and port ends intact.

Custom Packaging Solutions

We offer flexible customized packaging services. The packing scheme can be tailored based on pipe specifications, order volume, container loading conditions and customers’ personalized technical and delivery requirements.

Container Shipment

Ideal for standard-sized pipes and small to medium batch orders, container shipping ensures safe, convenient and cost-effective global transportation for regular orders.

Bulk Vessel Shipment

For large-volume orders, as well as ultra-long and oversized seamless pipes that cannot fit standard containers, bulk vessel shipping is available to meet heavy cargo delivery demands.

Professional Loading & Fixing

Our team adopts standardized loading and fastening methods. Pipes are neatly arranged and firmly fixed in vessels or containers to prevent shifting, scratching and structural deformation throughout the entire shipping process.

Global Delivery Support

We support mainstream international trade terms including FOB, CFR and CIF. Complete sets of formal export documents will be provided to guarantee smooth customs clearance and project delivery for global clients.

Transportation: Express (Sample Delivery), Air, Rail, Land, Sea shipping (FCL or LCL or Bulk)

FAQ

Q1: Are your pipes fully compliant with ASTM A106 standards?

Absolutely. Our carbon seamless pipes are produced in strict adherence to ASTM A106 specifications. Chemical makeup, mechanical performance, dimensional tolerances and overall manufacturing quality are all kept under tight production control.

Q2: Is ASTM A106 pipe fit for high‑pressure and high‑temperature service?

Yes. Thanks to its seamless structure, the pipe delivers solid strength and outstanding pressure‑bearing performance. It is well‑suited for high‑temp, high‑pressure working conditions commonly seen within oil and gas sites, refineries, power facilities and various industrial piping networks.

Q3: What quality assurance measures do you implement?

Mill Test Certificates (MTC) and full inspection reports are available for every order. These documents cover chemical analysis, mechanical test results, dimensional checks and all other agreed‑upon technical criteria. Should buyers request it, independent third‑party inspection such as SGS can also be arranged.

Q4: Can you supply varied outer diameters, wall thicknesses and pipe schedules?

We maintain a broad selection of OD sizes, wall thicknesses and schedule grades. Custom work is also an option: we can perform cutting, end beveling, end capping, marking and other processing jobs to match your exact project specifications.

Q5: What export packing and shipping arrangements apply to ASTM A106 seamless pipes?

Pipes are tightly secured with steel strapping and wrapped in waterproof materials. Pipe end caps in plastic or metal can be fitted to add further protection. Both container and bulk vessel transport are available, and we work with standard international trade terms including FOB, CFR and CIF for overseas shipments.
