Low and medium pressure boiler pipe

Low and medium pressure boiler pipe uses steel ingot or solid tube to perforated capillary, and then dial made ​​by the hot-rolled, cold rolled or cold.

According to incomplete statistics, China's seamless pipe production enterprises is about 240 more than a seamless steel pipe unit is about more than 250 sets of production capacity of about 450 million tons. Seen from the caliber <φ76, accounting for 35% <φ159-650, accounting for 25%.

From a variety of general purpose of the 1.9 million tons, accounting for 54%; oil pipe 760,000 tons, accounting for 5.7%; hydraulic prop, precision tube 15 million tons, accounting for 4.3%; stainless steel pipe, tube bearings, automotive tube for a total of 50 000 tons, accounting for 1.4%.

Low and medium pressure boiler pipe executive Standard:

Low and medium pressure boiler pipe is used to create a variety of structures with low pressure boiler superheated steam roller pipes and locomotive boiler superheated steam pipe, opium pipe, small pipe and arch brick works of high quality carbon structural steel hot-rolled and cold pull (rolled) seamless tube.

Mainly used in industrial boilers and boiler in conveying low pressure fluid in the pipeline.

The representative of material 10, 20 steel.



Tech & Service of Seamless pipe

Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Seamless pipes dominates 65% of market share in Chinese boiler industry.

How to make seamless pipe(seamless pipe process)?
Hot Piercing Workshop
Piercing process
The cross roll piercing and pilger rolling process in the size range from approx. 250 to 660 mm outside diameter.
Precision cold drawn steel tube production process
Pipe weld cracks
often follow different mechanisms can be divided into two types of thermal cracking and cold cracking.
How to calculate a steel pipe and tube theoretic weight
Calculate a steel pipe?
Pipe fittings are necessary to join together pipes, or to change the direction of an existing pipe.
Pipe beveling
Pipe beveling is the process where an angle is formed between the edge of the end of a pipe or tube and a plane perpendicular to the surface.
Steel pipe cutting machine
Pipe cutting
Cutting tools have a grinding wheel piece cutting machine (also known as toothless saw), hand saw, cutter and other hand tools.
Packing the steel pipes
There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method.
