Product Description:

1Structure of Seamless Pipe: 

We are company that have many years experience and professional manager team and engineer team and sales team, sure we will provide you high quality of pipe and professioanl service.

Seamless pipe possesses a hollow section and without seam around the strip steel. It is made with solid bar or steel ingot by perforating machine. As the facture process does not include any welding, seamless pipes are considered to be stronger and more durable. Generally speaking, seamless pipe has better pressure resistance and security than other classifications, and was usually more easily available than welded pipe.

High working accuracy

High strength

Small inertia resistance

Strong therming dissipine ability

Good appearance

Reasonble price

Q:How long are the seamless tubes? Are they six meters long?
The production process of seamless steel tube in general can be divided into two kinds of hot rolling and cold drawing, cold-rolled seamless steel pipe production process than hot-rolled seamless steel pipe seamless pipe hot rolling to complex, diameter is generally greater than 32mm, thickness 2.5-200mm, cold-rolled seamless steel pipe outside diameter 6mm, wall thickness to 0.25mm cold rolling hot rolling high precision ratio.
Q:What does "buried steel pipe" 6*2SC100 mean?
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
Q:What is PE coated steel pipe? Seek explanation
The appearance of the native HDPE is milky white and is somewhat translucent in the narrow cross section. PE has excellent properties that are resistant to most life and industrial chemicals. Polyethylene (PE) pipe due to its unique advantages and is widely used in building water supply, drainage, underground drainage pipe, building heating, gas pipelines, electrical and telecommunications, industrial protective casing pipes, agricultural pipes etc.. The utility model is mainly used for urban water supply, urban gas supply and farmland irrigation.
Q:Where is a steel pipe casing usually used?
Classification of casing: rigid casing, flexible waterproof sleeve, steel pipe sleeve and iron sheet bushing, etc..
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Hot rolled seamless tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
Q:How to distinguish between steel pipe and spiral pipe material?
Steel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
SC in principle, it should be called water gas pipe, also called thick wall steel pipe;
Q:How many fasteners are there in a ton of steel tubes?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
Q:45 and 316 which steel tubes are of high hardness?
No. 45 steel for high-quality carbon structural steel, the hardness is not high machining, used to make the template, mould studs, guide column, subject to heat treatment. 45 steel quenched and tempered hardness between HRC20~HRC30; 45 steel quenching hardness between HRC55~58, the limit value of up to HRC62.
Q:DN150 welded steel tubes one meter multiple
Calculated theoretical weight (Kg) per inch of welded steel pipe = (outside diameter wall thickness) * wall thickness * 0.02466DN150 welded pipe, "150" means nominal diameter of 150mm. Its outer diameter is 165mm.
