Overview of Cracking Furnace Tube Products
In the ethylene cracking unit, carburization and coking of the cracking furnace are major issues that affect the long-term operation of the ethylene unit. Domestic ethylene production enterprises widely use heat-resistant alloy ethylene cracking furnace tubes, which have a high tendency for coking, short coke cleaning cycles, high energy consumption, high production costs, low efficiency, and seriously affect product quality and the environment.
In order to reduce coking, Qingdao NPA has independently developed a new generation of high-temperature alloy ethylene cracking furnace tubes, ensuring that the alloy maintains excellent high-temperature mechanical properties at temperatures above 1100 ℃. Developed NH1949 high-temperature alloy, an aluminum furnace tube material with excellent mechanical properties, anti carburization and anti coking properties.

◆ Working condition: 850-1050℃(max1100℃℃)
◆ Outer diameter:50-200mm
◆ (Pipe section) length: <6400mm
◆ Inner wall finish: Ras3.2μm (internal control 1.óum)
◆ Bayberry particle layer: ≤0.8mm
Provide complete supporting components:

NPA Added Value
Qingdao NPA - a global innovation leader in the high-temperature alloy industry
Qingdao NPA can provide you with cracking furnace tube bank devices, conversion furnace tube bank devices, superheated steam furnace devices, DRI devices, and various matching static castings. We will combine Qingdao NPA's unique professional knowledge, quality control, and reaction speed to timely and accurately deliver to achieve supply guarantee effect. Qingdao NPA's supply guarantee ability is in an international leading position.
Qingdao NPA provides a full range of centrifugal casting and static casting parts, including various models of castings such as pipe sections, return bends, elbows, lifting ears, Y-shaped parts, T-shaped parts, tees, and brackets, as well as 800+sets of various wooden and metal molds. The factory follows the lean management concept, and through IE analysis, the overall planning is designed according to single piece flow. During the production process, PLC control and argon protection are used. The unique foundation and cylindrical design of the independently owned horizontal centrifuge makes the pipe sections more dense. The furnace tube is pulled out from the pouring end and the tail end to ensure structural consistency. The inner hole processing uses a professional pulling and boring machine with independent property rights to ensure the consistency of the furnace tube wall thickness.
In addition to our high alloy system used in the production process, its huge added value also makes Qingdao NPA stand out in the fiercely competitive environment. Because we understand your problem, we can increase your sales revenue and profit by tailoring and optimizing our products and services.
