Purpuratus process container spreader production requirements
1. Similar products in the most cost-effective brand, high-strength Ni-Cr-Mo alloy steel by forging the material has good anti-fatigue ability, all products and components in heat treatment and after all the tests pass in Magnetic Particle Testing, performance in similar product.
2. All the quality norms in the United States are based on ASTM A-952-98 and EN1677-2000 version of the European union the implementation of the inspection,
3. For all products and spare parts required for the safety of 2.5 times the load, and 100% of the full implementation of pre-qualified in Latin America and the Netherlands seized the entire force to guarantee the strength of product heat-treatment works and toughness.
4. All the work needs a minimum strength required to meet the minimum (4 times) more than the safety of the load force.
5. Spectrometer Analysis of material to ensure that every batch of raw material composition of the correctness of the elements
6. All the hook after selling all the eddy current inspection to ensure the quality of the same hardness.
7. Workpieces larger product works due to fear generated in the forging of the use of ultrasound examinations within the cleft.
