About Shijiazhuang Zhongtai Pipe Technology Development Co., Ltd. - Industrial Machinery Supplier in China

Shijiazhuang, China hosts Shijiazhuang Zhongtai Pipe Technology Development Co., Ltd., which currently lists 14 active products in its catalogue. The company classifies its offerings under Industrial Machinery and Welding & Wire Mesh Machinery. Its portfolio includes equipment such as Slitting Line, Stainless Steel Pipe Mill, and various API‑compliant pipe mill lines. The product list also features Cold Roll Forming Machine, Multi‑Functional Pipe Mill and several welded tube production lines identified by ERW model numbers. Each entry corresponds to a specific manufacturing line or machine used in steel pipe and tube production.

The catalogue covers both upstream and downstream processing equipment for pipe manufacturing, ranging from metal strip preparation (Slitting Line) to final welded pipe output (High Frequency Welded Tube Mill Line ERW76). The inclusion of API‑labeled lines (e.g., API Tube Mill Line ERW508) indicates designs intended to meet API 5L specifications for oil‑field pipelines. The product set also contains ZTF Forming Process equipment, which is used for cold‑forming of tube sections. Overall, the supplier presents a comprehensive set of machinery for producing welded steel pipes, tubes and related wire mesh components.

Product Range and Specialties of Shijiazhuang Zhongtai Pipe Technology Development Co., Ltd.

The listed machinery spans several core segments of pipe production. Slitting lines prepare coil material into narrow strips, typically handling widths from 500 mm to 1 200 mm and speeds up to 300 m/min. Stainless Steel Pipe Mill and API Pipe Mill lines are engineered for electric resistance welded (ERW) pipe fabrication, commonly delivering pipe diameters from 57 mm to 1 219 mm with wall thicknesses that meet API 5L grades A and B. Cold Roll Forming Machines produce precise tube profiles, often specified in GSM 200‑400 and tolerances of ±0.2 mm.

Industry standards for such equipment include ISO 9001 quality management, CE marking for safety, and compliance with API specifications for pipe dimensions and mechanical properties. Typical welded pipe lines incorporate automated welding stations, non‑destructive testing (NDT) modules, and line‑side coating systems. Buyers frequently request performance data such as tensile strength of the welded seam (≥ 485 MPa) and dimensional accuracy (±0.3 % of nominal). The catalogue’s ERW model numbers (e.g., ERW325, ERW508) correspond to line capacities measured in tonnes per day, ranging from 30 t/d to 120 t/d in comparable installations.

Trade and Export Information - Shijiazhuang Zhongtai Pipe Technology Development Co., Ltd.

China remains a major exporter of industrial machinery, and equipment for pipe and tube production is commonly shipped to oil‑and‑gas hubs in the Middle East, infrastructure markets in Southeast Asia, and steel‑processing firms in Europe and North America. The HS‑chapter 84 classification for metal‑working machinery (e.g., 8429 for pipe‑making machines, 8428 for metal‑forming presses) is routinely applied for customs clearance of these items.

Importers usually require CE certification, ISO 9001 compliance, and, for API‑branded lines, proof of conformity with API 5L or API 5CT standards. Machinery is typically packed in robust wooden crates or bulk containers, with dimensions fitting 40‑ft containers (approximately 12 m × 2.4 m × 2.6 m). Common Incoterms include FOB Shijiazhuang port or CIF destination ports, allowing buyers to arrange inland transport and installation. Export documentation often includes a commercial invoice, packing list, CE Declaration of Conformity and, where applicable, a test report from an accredited third‑party lab.

Sourcing from Shijiazhuang Zhongtai Pipe Technology Development Co., Ltd. - Buyer Guidance

When evaluating Shijiazhuang Zhongtai’s equipment, buyers should request the latest ISO 9001 certificate and CE Declaration of Conformity to verify compliance with safety and quality norms. For API‑labelled pipe mills, request test reports demonstrating adherence to API 5L dimensional tolerances and mechanical property requirements such as minimum yield strength.

It is advisable to obtain detailed technical datasheets that list line capacity (tonnes per day), maximum pipe diameter, wall thickness range, power consumption and footprint dimensions. Samples of finished pipe produced on the line, or a virtual tour of the installation, can help confirm that the equipment meets the buyer’s specifications before finalizing the contract.

What categories of machinery does Shijiazhuang Zhongtai offer?

The supplier lists equipment under Industrial Machinery and Welding & Wire Mesh Machinery, covering slitting lines, stainless steel pipe mills, API‑branded pipe mill lines, cold roll forming machines and various welded tube production lines. Each product is intended for different stages of steel pipe and tube manufacturing.

What does the “ERW” designation in the product names refer to?

ERW stands for Electric Resistance Welded, a process that joins the edges of steel strip to form pipe. ERW lines are designed to meet API 5L specifications for pipelines used in oil and gas applications.

Which certifications are typically required for pipe‑making machinery from China?

Buyers usually request CE marking for safety compliance and ISO 9001 certification for quality management. For API‑labelled lines, additional test reports confirming conformity with API 5L or API 5CT standards are commonly required.

What typical lead time can a buyer expect for these machines?

Lead times for complete pipe‑making lines generally range from 12 to 24 months, depending on the selected capacity and any custom engineering. Complex lines with higher throughput may approach the upper end of this range.

What are the common packaging and shipping methods for this type of equipment?

Machines are typically packed in reinforced wooden crates or loaded directly into 40‑ft containers, matching standard container dimensions. Shipping terms often use FOB Shijiazhuang or CIF to the buyer’s destination port.

What documentation should be verified before import?

Importers should verify the commercial invoice, packing list, CE Declaration of Conformity, ISO 9001 certificate, and any API test reports attached to the shipment. These documents facilitate customs clearance and confirm product compliance.

Is a sample of the finished pipe produced by the line available?

Suppliers can arrange a sample run or provide data sheets showing pipe dimensions, wall thickness and mechanical test results from a trial production batch. Providing such samples helps buyers assess the line’s capability before placing a full order.
