About Hebei Senhaipipeline Co., Ltd. - Steel Pipes Supplier in China

Based in China, Hebei Senhaipipeline Co., Ltd. lists eight active products focused on steel pipe solutions. The catalogue covers pipe types for oil casing and tubing, ERW pipes for gas transport, high‑pressure boiler pipes, SSAW piling pipes, plate flanges, API 5L seamless pipes, anti‑corrosion pipeline sections, and pipe bends. Each product is associated with a specific HS‑code family such as 7304 for pipes, 7306 for piling products, and 7307 for flanges and fittings, reflecting standard customs classifications for carbon‑steel and stainless‑steel items.

The supplier’s product descriptions include material grades like Carbon Steel Grade SA‑210 A1 (ASTM A210), API 5L grades B to X65, carbon‑steel grades X42‑X65, and stainless‑steel grades 304/316 for flanges. HS‑codes cited in the catalogue are 7304.51 for high‑pressure boiler pipe, 7306.19 for SSAW piling pipe, 7307.91 for plate flanges, 7304.19 for API 5L seamless pipe, 7304.29 for anti‑corrosion pipeline, and 7307.23 for pipe bends. These codes align with the global tariff schedule for steel products.

Product Range and Specialties of Hebei Senhaipipeline Co., Ltd.

The eight listed items span a typical steel‑pipe product family used in oil & gas, power generation, and civil construction. API 5L seamless pipes (HS 7304.19) are offered from Grade B up to X65, matching the API specification for line pipe pressure ratings. ERW (Electric‑Resistance‑Welded) pipes for natural‑gas transport follow ASTM A53 or equivalent dimensional standards, while high‑pressure boiler pipe (SA‑210 A1, HS 7304.51) conforms to ASME Section II for carbon‑steel boiler applications. SSAW (Spiral‑Submerged‑Arc‑Welded) piling pipes (HS 7306.19) are supplied in grades B/B+ and X42‑X65, commonly used for deep‑foundation work. Plate flanges (HS 7307.91) are available in carbon steel and stainless steel 304/316, typically conforming to ASTM A182. The anti‑corrosion pipeline (HS 7304.29) uses API 5L grades B, X42, X52 with external coating systems, and the pipe bend (HS 7307.23) follows ASTM A234 WPB specifications for wrought pipe fittings.

Trade and Export Information - Hebei Senhaipipeline Co., Ltd.

China remains one of the largest exporters of carbon‑steel and alloy‑steel pipe products, with major destinations in the Middle East, Southeast Asia, Africa, and Europe. HS‑code 7304 covers seamless and welded steel pipes, 7306 includes structural steel for piling, and 7307 covers flanges, fittings and related accessories. Buyers typically require ISO 9001 quality‑management certification, API product certification, and PED (Pressure Equipment Directive) compliance for pressure‑rated pipe, especially when supplying the EU or North America. Third‑party inspection agencies such as SGS, Bureau Veritas or Intertek often provide mill‑test reports and conformity certificates. Shipping is usually performed in 20‑ft or 40‑ft containers for smaller dimensions, while longer pipe sections are dispatched on flat‑rack containers or bulk carriers, with FOB or CIF terms prevailing in most contracts.

Sourcing from Hebei Senhaipipeline Co., Ltd. - Buyer Guidance

When sourcing from Hebei Senhaipipeline, request the mill‑test report (MTR) that lists chemical composition, tensile strength, yield strength and impact test results for each grade. Verify that the API 5L and ASTM designations on the MTR match the product description and HS‑code on the commercial invoice. For anti‑corrosion pipeline sections, ask for coating specifications, thickness, and adhesion test results, as well as any relevant environmental certification (e.g., NACE). Samples of flanges or bends should be examined for dimensional tolerance (e.g., flange bolt‑circle diameter, bend radius) and surface finish before final acceptance. Confirm packaging details - wooden crates with protective padding for pipe sections, or steel drums for fittings - and ensure that the chosen Incoterm (FOB, CIF) aligns with your logistics plan.

What steel pipe grades are listed in Hebei Senhaipipeline’s catalogue?

The catalogue includes Carbon Steel Grade SA‑210 A1 (ASTM A210) for boiler pipe, API 5L grades B to X65 for seamless and anti‑corrosion pipes, and carbon‑steel grades X42‑X65 for SSAW piling pipe and ERW gas‑transport pipe.

Which HS‑codes apply to the products offered?

HS 7304.51 applies to high‑pressure boiler pipe, 7304.19 to API 5L seamless pipe, 7304.29 to anti‑corrosion pipeline, 7306.19 to SSAW piling pipe, 7307.91 to plate flanges, and 7307.23 to pipe bends.

What material standards are referenced for the flanges?

Flanges are supplied in carbon steel and stainless steel 304/316, conforming to ASTM A182 (for forged carbon‑steel) and the equivalent stainless‑steel specifications.

Are there typical certifications buyers should request for these steel products?

Buyers usually request ISO 9001 quality‑management certification, API product certification, and, where applicable, PED or CE marking for pressure‑rated pipe. Third‑party inspection reports (SGS, Bureau Veritas) are also common.

What are the common packaging methods for the listed steel items?

Pipe sections are typically packed in wooden crates with protective padding, while plate flanges and bends are shipped in steel drums or bundled on pallets to prevent deformation during transport.

Which markets commonly import steel pipes from China?

Major import markets include the Middle East (oil & gas projects), Southeast Asian countries, African infrastructure programmes, and European nations requiring pressure‑rated pipe for energy and construction sectors.

What documentation should a buyer verify before placing an order?

The buyer should verify the commercial invoice HS‑code, the mill‑test report matching the specified grade, any coating or anti‑corrosion certificates, and ensure that the terms of delivery (e.g., FOB, CIF) and packaging meet their logistics requirements.
