1) Excellent material. The product complies with the GB/T9440 standard. High quality scrap and coke are selected. The secondary temperature measurement of molten iron casting is supplemented by spectral composition inspection, sample block inspection and damage inspection to ensure the excellent and stable material of Tianhe Masteel pipe fittings.
2) Dimension angle standard. KANEF strictly inspects the dimensions and angles of pipe fittings, and the overall dimensions of the products meet the requirements of GB/T3287 standard. The thickness and dimensions are standardized, and the installation is convenient and simple.

3) The thread is long and smooth. Tianhema steel pipe fittings are threaded with round handle round bottom tap. The thread meets the requirements of GB/T7306.2 standard, the thread is strict and stable, the thread is long and the thread is smooth and full, the thread has no damage to the inner wall of the pipe fitting, the pipe fitting angle meets the requirements of GB/T3287, and the size is accurate.

4) Advanced production technology. Fully automatic molding and casting production, internationally advanced Danish DISA sand mixing line, double furnace smelting technology of blast furnace+electric furnace, 72 hour electric annealing process, secondary shot blasting+placing into the kiln, full-automatic pickling+electric hot galvanizing are adopted. Advanced technology and guaranteed quality.

5) Details determine quality. Tianhe measured the temperature twice before each ladle of molten iron was taken out of the furnace and cast, and the composition was analyzed and tested by the German Oxford Spectrometer to ensure that the pipe material was stable and excellent. Seven inspections, five inspections and three inspections throughout the production process ensure the performance of pipe fittings. Carnev promises that the manufacturer will pay 200 yuan for every sand hole through hole pipe found by the customer.

6) The package is firm. Pipe fittings shall be treated with Flowserve water-based antirust oil. Double layer woven bag packaging, the number of packages is smaller, the packaging is stronger, and the handling is more convenient.

7) Perfect after-sales service.

8) Quality assurance.

9) Professional certification. The company has passed ISO9001 quality certification, with good quality and more confidence.
