200mm stainless steel test sieve set

The 200mm stainless steel test sieve set is designed for laboratory particle size distribution analysis. It consists of stainless steel sieve frames with selected mesh sizes, a receiver pan, and a top lid. Sieve specifications are available in accordance with ASTM E11 and ISO 3310-1 requirements, with mesh configurations available for coarse particles, powders, and fine particle analysis.

Why Our 200mm Sieve Set Performs Better

Tensioning & Mesh Uniformity

Mesh tension and aperture uniformity directly dictate the repeatability of test results. During manufacturing, a pneumatic quantitative tensioning system evenly stretches the stainless steel woven wire mesh to a predetermined tension before fixing it into the frame. Mesh apertures are scanned and inspected aperture-by-aperture using a computer image analyzer, controlling the aperture deviation per square centimeter within the tolerances specified by ISO 3310-1 (e.g., ±2.1 μm tolerance for 75 μm mesh). This tensioning process eliminates mesh sagging or localized dipping during sieving vibrations, maintaining a consistent particle passing rate.

Seamless Laser Welding

A 360-degree continuous laser welding technique is applied at the junction between the sieve frame and the woven mesh. Compared with traditional soldering or clamping bar fixation, seamless laser welds present a smooth, flat surface free of crevices and burrs. Structurally, this prevents sample particles from trapping in the frame edges, eliminates cross-contamination between samples, and enhances cleaning smoothness. The frame itself is stamped from a single piece of stainless steel plate with a wall thickness of 1.0 mm, maintaining structural stability when multi-layered stacks endure vertical and horizontal vibrations.

Calibration & Traceability

Prior to dispatch, each sieve undergoes testing via NIST-traceable standard glass microspheres, and wire diameter as well as mesh open area percentage are measured under optical microscopes. A unique laser-etched identification code (including serial number, production batch number, nominal mesh size, and aperture dimension) is permanently marked on the outer wall of every frame. A factory inspection certificate is included, detailing the average aperture size, upper limit values, and international standard codes met, facilitating annual laboratory calibration and quality system auditing.

Frequently Asked Questions

Q: What is a 200 mesh sieve and how does it fit into this 200mm set?

A: A 200 mesh test sieve refers to a woven wire cloth containing 200 openings per linear inch (25.4 mm), corresponding to a nominal aperture size of 75 micrometers (0.075 mm). In a 200mm test sieve set, the 200 mesh sieve is typically positioned in the lower-middle portion of the stack as a division point between medium-fine and micro powders. Since 200mm refers to the external physical frame diameter, the 200 mesh wire cloth is secured inside this 200mm frame, providing approximately 280 square centimeters of mesh filtration area for 75-micron particle passing.

Q: How big is a No. 200 sieve?

A: According to the ASTM E11 standard, "No. 200" designates a 200 Mesh sieve with an aperture opening size of 75 micrometers (μm) or 0.0029 inches. In terms of physical dimensions, this 200mm specification No. 200 sieve has an outer diameter of 200 millimeters (7.87 inches), a full-height wall height of 50 millimeters, and a half-height wall height of 25 millimeters.

Q: How to clean and maintain a 200mm stainless steel test sieve?

A: Cleaning and maintenance require differentiated approaches based on mesh size:
Coarse Mesh (less than 100 mesh): Use a soft nylon brush under warm water, gently brushing along the direction of the wire weave to remove trapped particles.
Fine Mesh (200 mesh and above): Hard brushes or metal picks are strictly prohibited to prevent wire displacement and deformation. Submerge the sieve in an ultrasonic cleaner filled with water and neutral cleaning agent for 2-5 minutes.
Drying & Storage: After cleaning, place in an oven at 80°C–100°C to dry. Once water evaporates, store in a dry cabinet.

Q: What factors affect the price of a 200mm test sieve set?

A: The price of a 200mm test sieve set is determined by the following elements:
Stack Layers & Composition: The number of sieve frames included, plus whether a top lid and receiver pan are configured.
Material Selection: Standard AISI 304 stainless steel carries a lower cost than AISI 316L used under acidic or corrosive environments.
Mesh Count & Craftsmanship: Ultra-fine wire weaving and inspection costs for high mesh counts (e.g., 400 mesh, 500 mesh, 635 mesh) exceed those for coarse meshes.
Calibration Certification Level: Cost variations exist between basic factory inspection reports and third-party calibration certificates containing detailed multi-point scan data.
