Industry standards for quartz glass tube

Quartz glass tube is high-temperature, high-pressure, and corrosion-resistant. Scientists use them in chemistry, biology, and medicine. We must set standards to ensure the quality of quartz glass tubes.

I. Material Requirements

1. Manufacturers should make quartz glass tubes from high-quality, clear, natural quartz crystals.

2. We must process quartz crystals in several steps. This will remove impurities and bubbles. It will ensure their purity and transparency.

3. After processing, quartz crystals should have a uniform wall thickness. Their inner and outer surfaces must be smooth.

II. Appearance Requirements

quartz glass tube

1. Quartz glass tubes must be colorless and transparent. They should have no color spots or foggy points.

2. The surface of quartz glass tubes should not have cracks, bubbles, or notches.

3. Both ends of quartz glass tubes should be flat, without protrusions or cuts.

III. Dimensional Requirements

1. Quartz glass tubes must have a uniform inner diameter and wall thickness. They must meet the design specs.

2. The length error of the tube should not exceed ±0.5 mm.

3. The parallelism error at both ends of the tube should not exceed 0.1 mm.

IV. Physical Performance Requirements

1. Compressive strength: Quartz glass tubes must withstand 30 MPa at room temperature. They should not crack or deform.

2. Tensile strength: Quartz glass tubes must not crack at room temperature under a tensile force of 10 MPa or greater.

3. Heat resistance: Quartz glass tubes must withstand environments above 1,000 °C.

4. Corrosion resistance: Quartz glass tubes must resist acid and alkali corrosion. They should withstand acid and alkali at less than 50% concentration.

V. Packaging Requirements

1. Quartz glass tubes must have professional packaging to prevent damage in transit.

2. The packaging box must show the product name, model, quantity, and more. It should also include a quality certificate and a product manual.

In conclusion, we must set clear standards. They ensure product quality and protect users. We can only make high-quality, stable quartz glass tubes by following the standards. This will provide better products and services to users.
