Frequently Asked Questions
Q1: What material options are available for your testing fixtures, and how to select the appropriate material based on application scenarios?
Our fixtures primarily adopt 45# carbon steel and 304#/316# stainless steel as core materials, with optional titanium alloy for special high-corrosion environments. 45# carbon steel offers excellent mechanical strength and cost-effectiveness, suitable for general industrial testing. 304#/316# stainless steel features superior corrosion resistance, ideal for testing in humid, corrosive, or high-purity environments. All materials undergo strict quality inspection to meet ISO 9001 production standards, ensuring structural stability and service life.
Q2: What is the clamping diameter range of your fixtures, and how does the split-type structure ensure compatibility with different pipe sizes?
Our standard fixtures cover a wide clamping diameter range from φ10 mm to φ2000 mm, with customizable solutions for non-standard sizes. The split-type design allows flexible adjustment of the clamping opening, enabling compatibility with pipe diameters within a specified range. The automatic centering function ensures precise alignment with the pipe axis during clamping, avoiding uneven stress on the pipe and ensuring sealing reliability.
Q3: What is the clamping precision and sealing performance of your fixtures, and what technical measures are adopted to achieve this?
The clamping precision of our fixtures is ±0.1 mm, and the radial runout during clamping is ≤0.3 mm. We adopt a "clamp-first, seal-later" structural design combined with high-quality silicone rubber O-rings for radial sealing. The one-time clamping and sealing success rate reaches 100%, with a leakage rate of ≤0.01 MPa/min under rated test pressure. Key technical measures include CNC-machined clamping surfaces and adjustable compression bolts for uniform sealing pressure control.
Q4: What production processes are used for your fixtures, and how to ensure product consistency and quality stability?
Our fixtures are manufactured through a rigorous production process: precision casting of key components, CNC machining with dimensional tolerance controlled within ±0.05 mm, heat treatment of carbon steel components, and assembly with 100% factory testing including clamping force test, sealing leakage test, and high-pressure endurance test.
