DN900 waterproof casing 02s404 flexible waterproof casing

What is the difference between the material of waterproof casing? What is the difference between ductile iron flexible waterproof casing and cast steel flexible waterproof casing? The flexible waterproof casing produced by Gongyi Yucheng Water Supply Equipment Co., Ltd. is produced in accordance with the waterproof casing atlas stipulated by the Ministry of Construction. , the main material is ductile iron, cast iron, cast steel, etc. Today we will introduce the difference between cast steel flexible waterproof casing and ductile iron flexible waterproof casing
Ductile iron waterproof casing material Ductile iron has chemicals other than iron The ingredients are usually carbon, silicon, manganese, phosphorus and sulfur, with the total amount not exceeding and an appropriate amount of rare earth magnesium and other spheroidizing elements.
Cast steel Cast steel is a general term for iron-based alloys used to produce castings that do not undergo eutectic transformation during solidification. A type of casting alloy. Cast steel is divided into cast carbon steel, cast low alloy steel and cast special steel.
The biggest difference between these two types of flexible waterproof casings is the material. Others such as the inner diameter and outer diameter are produced according to the atlas, so there is not much essential difference in use and installation. The production is mainly based on actual conditions. The flexible waterproof casing produced by Gongyi Yucheng Water Supply Equipment Co., Ltd. is mainly made of cast steel. Welding has very high requirements. The quality of the waterproof casing produced is stable and reliable.
