ASTM A297 HK Casting Pipe,Seamess Pipe,ASTM A297 HK Pipes,Centrifugally Cast Straight Radiant Tubes  

Centrifugal casting is without casting defects and holes

  One-piece construction – always better than weld

  Saving cost beacause of long lifetime 

  Mechanical properties are almost equal to forging

Centrifugal cast tube:

1. The centrifugal radiant tubes are of good heat, corrosion, wear-resistant properties, working at high temperature environment on average: 800 to 1200°C, which are used in the steel mills, like CAL (continuous annealing line), CGL (continuous galvanizing line)

2. Process:  Centrifugal casting, precision casting and machining.

3. Materials Standards: ANSI, ASTM, ASME, DIN, GB 

  Materials: High nickel and high chrome heat resistant alloys, cobalt base alloys, like HU, HT, HK, HP, HW, 24/24NbTiZr, 50Cr/50Ni (2.4813), 1.4865, 1.4849, 1.4848, 1.4410, 1.4059, 1.4841, 1.4845, 1.4852, 2.4879 or as per customer’s requirements

4.  We have in-house facility for each inspection: composition by spectrometer, size test, mechanical test, NDT/UT/RT/PT/MT/ET

5. Advantages: More than 25 years of professional experience and continuous R&D efforts enable us to offer better custom design and engineering advice.
