spiral steel pipes (ssaw) and seamless steel pipes (smls) are relatively common pipes in life, and they are used in house decoration and construction. so what is the difference between spiral steel pipes and seamless steel pipes? then let's find out about it.what is a spiral steel pipe?spiral steel

as we all know, large-diameter spiral steel pipes (ssaw) have a wide range of applications. they can be used in oil and gas pipelines, as well as in waterproofing and leakproofing of concrete structures such as sewage tanks, toilets and basements, among other applications. all in

the seamless pipe (smls pipe) passes through the billet saw section of the steel mill, and then is heated in the ring furnace - perforated - sized - straightened - cooled - saw head - packaged into a qualified finished product. generally, it cannot be placed in the production workshop when it is del

according to different conditions, the metal material is heated to a suitable temperature and kept warm, and then cooled in different ways to change the metallographic structure of the metal material and obtain the required structural properties. this process is often referred to as heat treatment o

there are many things that should be paid attention to in the whole heat treatment process of thick-walled seamless steel tubes. for example, the correct setting of the furnace is very important, so as to ensure a smooth cyclone in the furnace, and also make the thick-walled steel tubes receive unif
