About Dalian Etdz Xiupu Science Co, Ltd - Heaters Supplier in China

China‑based Dalian Etdz Xiupu Science Co, Ltd lists five active products across four primary categories: Heaters, Power Plants, Metal Castings & Forgings, and Flanges. The catalogue includes equipment for thermal energy generation such as Cfb boilers, pulverized‑coal fired boilers and a small hydro power station, as well as metal components like auto castings and a membrane water‑cooled wall welding line. Each product is identified by its HS‑code family where applicable, linking the auto castings to HS chapter 73 (code 7325.10) and the welding line to HS chapter 85 (code 8515.31).

The supplier’s portfolio reflects typical Chinese export offerings in the energy and metal‑fabrication sectors. Boiler products generally fall under HS 84 (boilers, machinery for heating) and are engineered for pressures up to several tens of bar and efficiencies above 85 %. Auto castings listed under HS 7325.10 are produced in ductile iron, gray cast iron and aluminum alloy, grades that meet ASTM A536 or ISO 1083 specifications. The welding line, classified under HS 8515.31, is designed for carbon‑steel and alloy‑steel plates used in boiler construction and conforms to welding standards such as ISO 3834 or EN 1090.

Product Range and Specialties of Dalian Etdz Xiupu Science Co, Ltd

The catalogue’s boiler range includes a circulating fluidized‑bed (Cfb) boiler, a pulverized‑coal fired boiler and a small hydro power station. In the industry, Cfb units are valued for fuel flexibility and low emissions, typically rated between 10 MW and 200 MW with outlet temperatures around 850 °C. Pulverized‑coal boilers commonly operate at 30 - 150 bar and meet ISO 15500 performance criteria. Small hydro stations are usually under 10 MW and follow IEC 61400‑2 guidelines for water‑power equipment. The auto castings entry under HS 7325.10 covers ductile iron (often SG‑iron with tensile strength 450‑600 MPa), gray cast iron (class G‑20) and aluminum alloys (e.g., Al‑Si 10). The membrane water‑cooled wall welding line, HS 8515.31, is a carbon‑steel welding system designed for boiler‑grade plates, typically supporting welding currents of 400 - 800 A and conforming to AWS A5.1 or EN ISO 15614‑1 welding procedures.

Trade and Export Information - Dalian Etdz Xiupu Science Co, Ltd

China remains a leading exporter of industrial boilers, metal castings and welding equipment, with major destinations in Southeast Asia, the Middle East, Africa and Europe. HS 84 xxx codes for boilers and HS 73 xxx for castings are routinely inspected under Chinese customs export controls and may require a Certificate of Origin and a commercial invoice. Buyers often request ISO 9001 quality‑management certification, CE marking for equipment entering the EU, and compliance with ASME‑Section II for pressure vessels. Packaging for boilers typically involves wooden pallets, steel frames and shrink‑wrap, fitting into 20‑ft or 40‑ft containers; castings are usually crated in wooden boxes with protective padding. Standard Incoterms such as FOB Shanghai or CIF Dubai are common for these heavy, high‑value items.

Sourcing from Dalian Etdz Xiupu Science Co, Ltd - Buyer Guidance

When sourcing from Dalian Etdz Xiupu Science Co, Ltd, buyers should obtain material test reports for each casting grade, pressure‑test certificates for boiler units, and welding procedure specifications for the welding line. Requesting ISO 9001 or CE documentation confirms that the supplier follows recognized quality systems. Verify that the HS‑code declarations match the product description on the commercial invoice to avoid customs delays. Typical minimum order quantities are one full container load for heavy equipment, with lead times ranging from 8 weeks for standard boiler models to 12‑16 weeks for custom‑cast components.

What types of boiler equipment does the supplier list?

The catalogue includes a circulating fluidized‑bed (Cfb) boiler, a pulverized‑coal fired boiler and a small hydro power station, each classified under HS codes for boilers and heating machinery.

Which materials are used for the auto castings?

Auto castings are offered in ductile iron (SG iron), gray cast iron and aluminum alloy, referenced under HS 7325.10 and meeting typical ASTM A536 or ISO 1083 grades.

What is the HS code for the membrane water‑cooled wall welding line?

The welding line is listed with HS code 8515.31, which falls under the electrical machinery chapter for welding equipment.

Which certifications should a buyer request for these products?

Buyers should ask for ISO 9001 quality‑management certificates, CE conformity declarations for EU markets, and pressure‑test certificates or ASME compliance for boiler units.

What are typical packaging and shipping methods?

Boiler units are usually palletised, crated and shrink‑wrapped for container loading (20‑ft or 40‑ft). Castings are crated in wooden boxes with protective padding, also container‑ready.

What is a reasonable lead time for a custom casting order?

Custom auto castings generally require 12‑16 weeks from order confirmation, depending on the alloy grade and post‑processing requirements.

How can a buyer verify the material grade of a casting?

Request a material test report that includes chemical composition, tensile strength and hardness values aligned with ASTM A536 or ISO 1083 standards.

Are there any typical minimum order quantities?

For heavy equipment such as boilers, the practical minimum is often one full container load; for smaller castings, a single pallet may be accepted, subject to the supplier’s production schedule.
