About Hengshui Honghao Garment Factory - Industrial Valves & Gauges Supplier in China

Hengshui Honghao Garment Factory is based in China and lists eight active products. The catalogue covers glass and metal components used in industrial valves and gauges, including Reflex Gauge Glass, Transparent Level Gauge Glass, Round Sight Glass, Borosilicate Glass Tube, Quartz Round Glass (HS code 7007.11, material Borosilicate Glass), Aluminosilicate Glass, Stainless Steel Reflex Level Gauge and Transparent Level Gauge made from Carbon Steel. Each item falls under the broader HS‑code families for cut glass (chapter 70) and for measuring, checking or controlling instruments (chapter 90).

The supplier’s product set combines transparent glass sight‑components with metal level‑gauge assemblies. Glass items are described by material type - borosilicate, aluminosilicate, quartz - while metal gauges specify stainless steel or carbon steel construction. No additional certifications or compliance statements are provided in the source data.

Product Range and Specialties of Hengshui Honghao Garment Factory

The eight listed items span two material families: engineered glass (borosilicate, aluminosilicate, quartz) and stainless or carbon steel gauge housings. In the glass sector, buyers commonly encounter grades such as borosilicate glass with a thermal shock resistance of 150 °C temperature difference, aluminosilicate with higher chemical durability, and quartz glass meeting optical purity levels of 99.9 % SiO₂. Typical specifications include thicknesses from 2 mm to 10 mm, optical clarity measured by transmission >90 %, and surface flatness within λ/4. Metal gauges are usually fabricated to ISO 9001 quality management, with pressure ratings from 0.1 MPa to 2 MPa and corrosion resistance conforming to ASTM A240 for stainless steel or ASTM A36 for carbon steel.

Trade and Export Information - Hengshui Honghao Garment Factory

China is a major exporter of industrial glass components and gauge assemblies. Products classified under HS 7007 (cut glass) are frequently shipped to Europe, North America and Southeast Asia for use in process control, chemical processing and pharmaceutical equipment. Gauge assemblies fall under HS 9026 (instruments for measuring pressure, temperature, etc.) and are similarly demanded by manufacturers in the automotive, oil‑and‑gas and food‑processing sectors. Buyers typically request conformity to IEC 60529 (IP rating) and ISO 9001 quality systems; third‑party inspections such as SGS or Bureau Veritas are common. Standard export packaging includes wooden crates or reinforced pallets, with 20‑ft or 40‑ft containers as the usual shipping mode, often on CIF or FOB terms.

Sourcing from Hengshui Honghao Garment Factory - Buyer Guidance

When sourcing from this supplier, request mill test reports that detail glass composition, thermal expansion coefficient and impact resistance, as well as metal certification sheets confirming ASTM grade and pressure test results. Ask for a physical sample of the gauge glass to verify optical clarity and dimensional tolerance before confirming bulk orders. Common minimum order quantities range from 100 to 500 units per glass type, with lead times of 4‑6 weeks after sample approval. Verify that packaging meets ISPM 15 standards for wooden pallets and that the supplier can provide a full packing list aligned with the HS codes 7007.11 for quartz glass and 9026 for gauge assemblies.

What material specifications apply to the Quartz Round Glass listed under HS 7007.11?

The quartz round glass is made from high‑purity borosilicate glass, typically meeting a thermal shock resistance of at least 150 °C and an optical transmission above 90 %.

Are there standard pressure ratings for the stainless steel reflex level gauge?

Stainless steel reflex level gauges are generally rated for pressures between 0.1 MPa and 2 MPa and are fabricated to ASTM A240 specifications.

Which certifications should a buyer request for the glass products?

Buyers should request mill test reports, chemical composition certificates, and, where required, compliance with IEC 60529 for ingress protection and ISO 9001 quality management.

What is a typical minimum order quantity for the transparent level gauge glass?

Typical MOQs are 100 units per glass type, though the exact figure depends on the specific thickness and size required.

How are the glass items usually packed for international shipment?

Glass components are commonly packed in double‑wall cardboard boxes with foam inserts, placed on wooden pallets that comply with ISPM 15 treatment.

What lead time should a buyer expect after sample approval?

After sample approval, production lead time is usually 4 to 6 weeks, subject to material availability and any custom tolerances.
