Scope

4 Technical Requirements 4.1 The grease filling operation shall be carried out after the completion of the compression and crimping of the steel anchors of the tension clamps and the crimping of the aluminum pipes. 4.2 The grease shall have a product quality certificate and a factory inspection report, and the filling material requirements shall comply with the provisions of DL/T 373. In addition, the grease shall have radiation absorption characteristics that are significantly different from those of aluminum and air under X-ray irradiation, ensuring that the filling status of the grease, bubbles, and cavities can be clearly distinguished under X-ray inspection. 4.3 The filled cavities shall be inspected using X-ray penetration technology, and X-ray equipment and techniques that meet the inspection requirements shall be used to ensure that bubbles or cavities with a diameter of not less than 1 cm can be clearly distinguished. A filling rate of ≥95% is considered acceptable, and a filling rate of <95% requires additional grease filling. 4.4 The grease injection gun shall have sufficient pressure and be able to connect to the grease injection threaded holes using quick-connect fittings. The volume of the grease injection gun shall be greater than the recommended grease injection quantity for filling a single crimped pipe without compression zones. 4.5 The grease injection threaded holes shall be M5×1, located near the steel anchor end of the tension clamp in the non-compression zone. 5 Grease Injection Process 5.1 Before grease injection, check the model, batch number, expiration date, and appearance (no hardening, segregation, or impurities) of the grease; check the appearance and integrity of the grease injection gun, its functions and performance, safety, and maintenance. 5.2 Check the size, location, and integrity of the grease injection holes, and refer to Figure 1 for the schematic diagram of the grease injection type tension clamp structure and
