Basic introduction:
Internally threaded pipe is used for boiler evaporating hot surface, and the inner surface is rolled with a seamless steel pipe with a threaded channel.
1. The product is suitable for making the water wall of the power station boiler and fireplace, which can effectively eliminate the steam film on the inner wall of the steel pipe and improve the efficiency of the fireplace.
2. The product is manufactured by cold drawing, so that the inner wall of the pipe wall forms the inner wall spiral ribs of special geometric dimensions. The finished product adopts protective gas for stable performance and good surface quality.
3. Products are ordered according to customer needs

Application:
Boiler or Heat Exchanger
Feature:
Internally threaded seamless steel pipe (referred to as internal threaded pipe) refers to a seamless smooth pipe whose inner wall is processed into a spiral groove.
Compared with the usual light pipe, the inner threaded pipe can effectively prevent the formation of steam film between the water and the pipe wall, increase the disturbance of the flow in the steel pipe, and make the temperature of the pipe wall more uniform, which can not only prevent the steel pipe from burning out, but also improve the boiler's performance. heat transfer efficiency.
The number of thread heads of the internal threaded pipe varies from 4, 6, 8 and 12 according to the needs. The main materials are 20G, SA210C, SA213T2, SA213T12, 12Cr1MoVG, 15CrMoG, SA213T22, SA213T23
Packaging:Wooden cases or according to client’s requirements
Shipping: Land transportation/Ocean transportation
