It can be transported with using professional wood packaging to the packing, its excellent quality has won high praise at home and abroad.

wet rolls for tunnel furnaces
HEXIN water cooled rolls have been performing well in tunnel furnaces throughout the world ,which are made by high nickel alloy tires welded to steel shaft, including a castable refractory or without the refractory.
The wet rolls perform well in atmospheres over 1300 degrees  C. 
The nickel alloy tires are made from heat reistant stainless steel like 2.4879, by lost wax invesment casting method with special heat treatment.
We also supply customized alloy tires or ring to customers for installation by themself.
We also produce other castigns for CSP plants, like dry rolls for tunnel furnaces, riders for walking beam or pusher type reheating furnaces in nickel and cobalt based alloys, looper rolls, run out table rolls, wrapper rolls.
Other components for plate mill and tube mills like tube mill pierce points,plate mill heat treat hardening furnace rolls, rider tiles, hearth skids, buttons, drop-out skids,recuperator boxes, recuperator tubes

Reformer furnace tube

Furnace tubes for hydrocarbon steam reforming hydrogen production equipment, hydrocarbon steam reforming hydrogen production equipment, the equipment mainly includes: inlet gas collection pipe, reformer tube, outlet gas collection pipe, upper and lower pigtail pipes, etc. Among them, the reformer tube is produced by the centrifugal casting process, and the working temperature is 900°C-1000°C, which is an important equipment for the hydrogen production reformer.
Our production and technical team has nearly 30 years of experience in this industry, and has the ability to produce 500 reformer tubes per month to manufacture these parts. We strictly follow the following international standards for centrifugal casting and static casting:
Centrifugal casting: HG/T 2601, ASTM A608, DIN 10295, JIS G5122
Static casting: HG/T 3673, ASTM A351
The material grades are strictly in accordance with the standards of customers in different countries. The commonly used material grades are:
ZG40Cr25Ni35Nb, ZG40Cr35Ni45Nb, HP-Nb, HT50, GX40NiCrSiNb35-26, GX40NiCrNb45-35, G-NiCr28W, SCH24XNb
Supply specifications of conventional centrifugal casting products:
Reformer tube: outer diameter 100mm-300mm, wall thickness 8mm-20mm;
Hot wall gas collector: outer diameter 100mm-400mm, wall thickness 10mm-40mm;

Hydrogen production units are generally designed to produce hydrogen by using the process route of hydrocarbon-steam reforming method to generate gas and PSA method to purify and purify. The reformer is the key equipment of the device, and it adopts a top-fired flue gas descending double-sided radiation box furnace type.
Like the general heating furnace, the reformer also includes a radiation chamber and a convection chamber. The difference is that the radiation chamber of the reformer is essentially a multi-tube parallel-flow external heating reactor, and each furnace tube is a direct flame. Heated conversion reactor.
Therefore, the furnace tube is generally also called a reforming tube, and a catalyst is installed in the tube, and the process medium (hydrocarbon and water vapor) absorbs heat in the tube while undergoing a chemical reaction. Another feature of the reformer is high temperature and high pressure. The inlet temperature of the reformer is 450°C, the outlet temperature of the medium is 850°C, and the maximum temperature of the furnace reaches 1100°C.
The temperature of the tube wall of the hydrogen production reformer is very high, and the material is generally HP-40Nb. Since before, the design institute has started to adopt the full cold wall manifold structure in the tube structure of the reformer.

The reforming tube is suitable for the natural gas steam reformer, which is the main equipment of natural gas steam reforming to syngas. 
It converts the natural gas and steam mixture into synthesis gas rich in hydrogen, carbon monoxide and carbon dioxide through the reforming tube ( reaction tube). 
The reforming tubes are heated by external radiation and contain nickel-containing catalysts.
