Cangzhou Enfei Pipeline Equipment Co., Ltd. is an excellent manufacturer of jacketed flanges in China. The jacketed reducing flanges are forged from raw metal round steel or steel plates under high temperature and pressure. Therefore, jacketed flanges have high requirements on raw materials. The high quality of raw materials determines the quality of jacketed flanges products.

Next, the performance of the jacketed flanges is determined by the heat treatment process. The heat treatment temperature is usually between 700 and 1300 degrees Celsius. The heat treatment process determines the standard parameters such as low temperature impact resistance, high temperature resistance, corrosion resistance, welding performance and hardness.

Cangzhou Enfei Pipeline Equipment Co., Ltd. is an excellent manufacturer of jacketed variable diameter flanges, using the raw materials produced by the best factories in China, including Yongxing Special Steel, AVIC Shangda, Huaxin Lihua, Qingtuo Group, Laiwu Steel, Valin Steel, Taiyuan Steel, Shanghai Baosteel, Baosteel and other China’s best steel groups. The above raw material manufacturers have been certified by ABS and DNV GL, BV, LR, CCS, NKclass, KR, RINA and RS classification societies. The classification society can issue EN10204 3.2 and EN10204 3.1 bill of materials certificates.

Cangzhou Enfei Pipeline Equipment Co., Ltd. focuses on serving global customers. Manufacturing standards include: SH/T3426, HG/T20615 and customized drawings.
