Grooved pipe fittings, as key components in modern piping systems, directly impact installation efficiency and system safety due to their appearance quality and standardized markings. my country’s GB5315 standard sets forth clear technical requirements for the appearance and markings of groove lock fittings, providing crucial guidance for enterprise production and user acceptance.
Groove lock pipe fitting should have a smooth, clean surface, free from processing defects and impact damage, and free from cracks, shrinkage cavities, cold shuts, slag inclusions, porosity, scars, etc.; the coating should be uniform and firm, without bubbles or paint buildup; the rubber sealing ring should be free of bubbles, impurities, cracks, unevenness, and other defects; and the markings should be complete and clear. (The image below shows a typical defective product.)
DINSEN grooved pipe fittings strictly adhere to the GB5315 standard and achieve multiple breakthroughs in process and performance:
We utilize advanced casting and automated production lines to ensure a smooth, flawless surface. Through a unique anti-corrosion process, the zinc layer thickness is 30% greater than the national standard, providing durable corrosion resistance even in harsh environments. Product information is deeply laser-engraved, ensuring clear, wear-resistant, and permanent markings, achieving full quality traceability.
While fully complying with national standards, DINSEN implements even stricter internal control standards and conducts 100% factory inspection to ensure industry-leading dimensional accuracy, sealing performance, and pressure resistance. User-friendly design combined with high-precision manufacturing makes installation simpler and faster, effectively improving construction efficiency and reducing overall costs.
In building engineering, fire protection systems, and industrial piping, DINSEN grooved pipe fittings have won widespread recognition for their superior quality and stable performance. We recommend that when selecting grooved pipe fittings, you should not only check whether the product meets the GB5315 standard, but also choose a brand like DINSEN with a rigorous quality control system and innovative technology to ensure the long-term safe and stable operation of the piping system.
