heat resistant radiant tube for petrochemical industry

heat resistant radiant tube for petrochemical industry 

U-type, W-Type, 0-Type, P-type, L-Type,S-Type, Straight-type, Electric radiant tubes.

Application:

The radiant tubes are  working at high temperature environment  on average: 800-1200°C,most of them are  used for indirect heating to furnace  like  CAL(continuous annealing line)CGL,(continous galvanizing line).

Process:

Centrifugal/spun casting method for tube sections, investment casting or sand casting for the bends,hangers,welding and machining.

Material:

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
