Low pressure boiler pipe

Low pressure boiler pipe is made from ingots or solid tube which have been perforated capillary, and then dial made by the hot-rolled, cold rolled or cold.

Seamless steel pipe has a very important position in China's steel industry, the low-pressure boiler tubes and high pressure boiler tubes also plays a important role in the seamless steel pipe. Their application environments are relatively poor and have requirements on temperature and pressure , so the production process of low-pressure boiler steel pipe and high pressure boiler tube is very strict.

Boiler tube means a steel products that open at both ends and has a hollow cross section, its length with the surrounding. According to production methods,it can be divided into seamless and welded steel pipe.

Implementation of standards GB/T3087-2008; representative of the material: 10 #, 20 #;

The main purpose of the low-pressure boiler tubes is used to manufacture a variety of low pressure boilers, superheated steam tube, boiling water tube, water wall tube and locomotive boilers superheated steam pipe, opium pipe, small pipe and brick arch pipe.

GeneralGB3087low-pressure boiler tubes can bear 130-140 kg of pressure; hydrostatic testing, crimping, flaring, flattening are done apart from ensuring chemical composition and mechanical properties. Hot-rolled delivery with hot rolled condition, cold-rolled (allocated) delivery heat treatment.

Seamless pipeSpecification, standard and identification

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.
