Hebei Bohai Tube Co., Ltd. specializes in producing carbon steel elbow 20. Buy 20 carbon steel elbow went to Hebei Bohai Sea. WB36 temperature strength of less than A335P22 temperature strength, high temperature plastic WB36 is less than the high temperature plasticity A335P22, the thermal conductivity is less than the thermal conductivity of A335P22 WB36's. Therefore, under the blank diameter, wall thickness and shape of the mandrel head scales the same situation, WB36 and die bonding functions less than A335P22. Pushing elbow demand normalizing heat treatment, machining port, thickness and machining allowances need to be left burning. Typically the wall thickness of the balance elbow theoretical 10% to 20%. Elbow-sectional diameter and wall thickness δ D ratio smaller than doubled 20 # carbon steel elbow, and function better fit the mold of 20 # carbon steel elbow, but the simple arc in the elbow wrinkling. 45 degree elbow on steel prices, steel 45 degree elbow fundamental process hot topic, people's opinions differ, I steel elbow | GB elbow manufacturer with years of rich experience in the production of carbon steel elbow The basic process of this topic has its own unique insights Road, GB 20 # carbon steel elbow, the following is the topic of our own view point, I hope you can help. First solder a polygonal cross-sectional polygonal ring shell or both polygonal blockade fan shell, the internal pressure washed over medium within the pressure applied, including the role of the cross-section under pressure from polygon gradually become round, eventually becoming a circular ring shells. Based on the needs of the marine 20 # carbon steel elbow, a circular ring shell can cut four or six 90 ○ 60 ○ elbow elbow elbow or other specifications, the process for the manufacture of elbow diameter and elbow inside diameter larger than any specifications elbow greater than 1.5, is the ideal way to present large-scale manufacture of carbon steel elbow.
