Fire clamp detection

Detection standard

  • Detection specification

The fire clamp of the detection project is often used in fire protection facilities such as fire hydrants and fire extinguishers, playing a role in fixing and connecting pipelines. The quality of fire clamps directly affects the safety and reliability of fire facilities, so the following testing items need to be carried out: size testing: testing whether the outer diameter, inner diameter, interface thickness and other data of the clamps meet the requirements of the specifications. Physical performance testing: including tests on the tensile strength, torsional strength, impact resistance, and hardness of fire clamps. Corrosion resistance test: Detect the corrosion resistance of fire clamp materials to prevent loose connections and water leaks caused by corrosion during use. Coating adhesion test: Test the surface coating adhesion of fire clamps to ensure that the surface coating is not easily peeled off and damaged. Reliability testing: testing the reliability and stability of fire clamps under different conditions, such as high temperature resistance, low temperature resistance, and pressure resistance. Sign inspection: Check whether the signs, handwriting, and numbers on the fire clamps are clear and eye-catching for easy management. Detection range T-shaped clamp: made of two mutually perpendicular threaded steel bars, with a circular gasket connected in the middle. Hole clamp: Usually composed of four bolts and a circular gasket, it can solve the connection between pipes of different diameters. Price Plate Clamp: Using a connection method similar to a hole clamp, but adding a price plate design to facilitate price marking and inspection of pipeline connections. Nut clamp: The two pipes are fixed together using a nut clamp method, which is more secure. Open end clamp: The upper half of the open end clamp can be opened to insert the pipeline, making it more convenient. Relevant reference standard specifications HB 9-1983: Clamp GB/T 5267.2-2017: Non electrolytic zinc sheet coating on fasteners GB/T 8259-2008: Technical conditions for clamp type flexible pipe joints GB/T 8260-2008: Types and dimensions of clamp type flexible pipe joints GB50974-2014: Technical specifications for fire water supply and hydrant systems GB/T 20174-2019: Petroleum and natural gas drilling and production equipment Drilling equipment GB/T 25430-2010: Specification for rotary blowout preventers of drilling equipment GB/T 25430-2019; Petroleum and natural gas drilling and production equipment - Rotary blowout preventers HB 3-9-1996: Removable clamps HB 3-30-2002: Purpose of handling inspection reports for stainless steel band clamps: 1. Evaluate the quality of products; 2. Determine the product quality level, i.e. the severity of defects; 3. Inspect the process flow and supervise the process quality; 4. Collect, statistics, and analyze quality data to lay the foundation for quality improvement and management activities; 5. Introduce arbitration inspection to determine the responsibility for quality accidents. The purpose of handling third-party testing reports is to obtain an independent, objective, and professional evaluation result to confirm whether the tested items or services comply with relevant regulatory standards, quality requirements, or technical specifications, and to verify their safety, reliability, and performance. Third party testing reports are typically used in areas such as product certification, market access, supply chain management, trade negotiations, and dispute resolution. Precautions for Testing Report: Carefully read and understand each section after receiving the testing report. Ensure that there is a "research and testing special seal" and official seal in the report, and check the anti-counterfeiting QR code to confirm its effectiveness. Confirmation information: Verify whether personal or organizational information is accurate and accurate. If the report is not stamped with the "Research and Testing Special Seal" or official seal, it is invalid. Pay attention to the test results: Focus on the summary and detailed information of the test results. If in doubt, consult relevant engineers and it is strictly prohibited to alter the report. Pay attention to the reference range: Check the reference range of the test results to see if the results are normal. As the reference range varies depending on factors such as samples, test methods, reference standards, etc., please contact our engineers to discuss your specific situation. Objection handling: If you have any objections to the test report, please file an appeal within 15 days of receiving the report. Late appeals will not be accepted.
