Kinds Of API Steel Pipe
- Feb 15, 2017 -

API carbon steel pipe is widely used in lots of industries.However,a lot of customers still don’t know how many kinds of API steel pipe are there on the market,Don’t worry about that.Here are the details.

API line steel pipe

API line steel pipe is the line pipe that meets the American Petroleum standard.Line pipe is used for transportation of oil,gas and water to the oil and gas industry enterprises.Ends of pipe include plain end,threaded end and socket end;their connections concludes end welding,coupling,socket connections,With the development of technology,API line of pipe’s range of applications is expanding gradually,especially in the large-diameter disaster.Coupled with the factor of cost,welded pipe have a dominant position in the field of line pipe,limiting development of stainless steel seamless line pipe.During2004,production of seamless line pipe is about 400,00t,ranging fromX42 to X70.API line steel pipe is divided into onshore line steel pipe and subsea line steel pipe.The production of high grade line steel pipe is currently adopting micro-alloying heat treatment technology.The cost of stainless steel seamless pipe is significantly higher than welded pipe.On the other hand,with the increase of steel grade,conventional technology of seamless steel pipe is difficult for producer to meet users’ requirements.At present API line steel pipe production plan are carrying out research work in order to improve its pipeline corrosion resistance and stable performance in environment of low or high temperature.

API seamless steel pipe

API seamless steel pipe is kind of long bar without seams around.This kind of pipe has hollow section.It is widely used for conveying fluids,such as oil,natural gas,gas and water.Manufacturing annular parts with API seamless steel pipe can improve utilization of material,simplify the process of manufacturing and save time of machining,such as bearing rings,jack sets etc.API seamless steel pipe is widely used for producing them.Compared to other materials,galvanized seamless steel pipe is lighter when they have same torsional strength.It is an economic cross-section steel,so it is widely used in the manufacture of structural parts and mechanical parts,such as drill pipe,automotive drive shafts,bicycle frames and construction using steel scaffolding etc.

API welded steel pipe

API straight seam steel pipe includes DSAW steel pipe and REW straight seam steel general API straight seam steel pipe are used for exploring.Painting,beveling,adding a cap and baling are important after finishing production.API straight seam steel pipe allows the existence of minor defects.Generally,the length of steel pipe exported is less than six meters because of the restriction of container size.You must have known different kinds of API steel pipe after reading the article above.Whether you are using or not ever used API steel pipe.the knowledge mentioned above is worthy of remembering.IF you can’t keep the knowledge in mind,come on and join favorites.
