First, the introduction of stainless steel seamless pipe
Stainless steel seamless steel pipe is a kind of pipe with corrosion resistance, high temperature, high pressure and other characteristics, which is widely used in petroleum, chemical industry, chemical fertilizer, pharmaceutical, shipbuilding and other fields. Its production process is relatively mature, mainly divided into cold drawing and hot rolling two ways, common materials are 304, 316, 321, 904L and so on.
Second, the material type of stainless steel seamless steel pipe
1. 304 stainless steel pipe
304 stainless steel pipe is a widely used material, mainly used to build indoor and outdoor channels, stairs, guardrail and so on. It has corrosion resistance, high temperature, high pressure and other characteristics, but is not suitable for acidic environments.
2. 316 Stainless steel pipe
316 stainless steel pipe is a high-quality stainless steel material, with corrosion resistance, high temperature, high pressure and other characteristics. It has more corrosion resistance than 304, and is suitable for chemical, pharmaceutical, shipbuilding, pharmaceutical and other industries.
3.321 stainless steel tube
321 stainless steel pipe is mainly made of titanium, which has more high temperature and corrosion resistance than 304 and 316. It is widely used in nuclear industry, aviation engine and other fields.
4. 904L stainless steel tube
904L stainless steel pipe is a high alloy stainless steel material with extremely high corrosion resistance, strength and high temperature resistance. It is suitable for a variety of corrosive environments, such as the chemical and petroleum industries.
