Industrial buyers usually search for a Tungsten Tube when the working temperature, furnace atmosphere or protection requirement is already beyond the comfort zone of stainless steel, nickel alloy or common ceramic parts. In these cases, the tube is not a decorative component. It has to protect sensors, guide heat, separate atmospheres or hold shape while the furnace is running.
Shaanxi Changlong Jiuzhou Metal Technology Co., Ltd. supplies pure tungsten tube, tungsten pipe and custom tungsten tubing for thermocouple protection, high temperature furnace assemblies and vacuum furnace applications. We focus on practical order details: outer diameter, inner diameter, length, tolerance, surface condition, end shape, quantity and packing method.
The five product display images on this page show small tungsten tubes, flanged tube ends, batch tubing, straight cut lengths and different tube sizes. These details matter because many furnace projects fail not from material grade alone, but from poor dimensional control, unclear drawings or weak protection during international shipment.
For furnace buyers, the right tungsten tube is not only a metal part; it is a heat-resistant barrier that must match temperature, atmosphere, tolerance and assembly method before production starts.
Tungsten Tube Supply for Furnace Buyers
Tungsten is selected for its high melting point, good strength retention at elevated temperature and low vapor pressure in vacuum environments. For buyers using vacuum furnace, hydrogen furnace or high temperature laboratory equipment, a tungsten pipe can provide stable service where ordinary metal tubes may deform, oxidize or contaminate the process.
Our tungsten tubing can be supplied as straight cut lengths, precision small tubes, sleeves, protection tubes and machined tube components. If a drawing is available, we can review the OD, ID, wall thickness, length, tolerance and surface requirements before quoting. If the buyer only has a sample or installation requirement, we can help convert the working conditions into a manufacturable specification.
Available Tungsten Pipe and Tubing Options
- Material: pure tungsten, with composition and inspection documents supplied according to order requirements.
- Product forms: tungsten tube, tungsten pipe, tungsten tubing, sleeves and custom machined tungsten tube parts.
- Dimensions: OD, ID, wall thickness and length can be discussed based on drawings or samples.
- Surface: ground, polished, cleaned or machined surface according to the assembly environment.
- Ends: straight cut, chamfered, stepped, threaded or other custom end treatment when technically feasible.
- Packing: individual protection, plastic tray, foam, carton or wooden case for export delivery.
Main Applications
Thermocouple Protection Tube
A tungsten thermocouple protection tube is commonly used where the thermocouple needs shielding from direct heat, vacuum atmosphere or mechanical contact. Buyers should confirm the sensor diameter, insertion depth, end closure requirement and whether the tube will be exposed to rapid heating or cooling. A small change in wall thickness can affect both response time and service life.
High Temperature Furnace
In a high temperature furnace, tungsten tube may work as a heating-related sleeve, support, shielding part or process tube. The choice depends on temperature, atmosphere, contact material and load. We recommend sending the operating temperature range and whether the furnace is used for sintering, heat treatment, crystal growth or laboratory testing.
Vacuum Furnace
Vacuum furnace buyers usually care about cleanliness, vapor pressure, deformation resistance and packing condition. For this application, surface cleaning and secure packaging are not secondary details. The tube should arrive clean, straight and protected from impact, especially when the wall is thin or the part has a small ID.
RFQ Checklist for Custom Tungsten Tube
To quote accurately, please include as many of the following details as possible. A drawing is preferred, but a clear specification list is also useful.
- Required material purity or standard
- Outer diameter, inner diameter and wall thickness
- Length and cut-to-length tolerance
- Quantity and expected delivery schedule
- Surface finish and cleaning requirement
- End shape, slot, step, thread or machining detail
- Operating temperature and furnace atmosphere
- Inspection documents, packing and shipping requirement

Inspection and Export Packing
Before shipment, tungsten tubes should be checked for basic appearance, dimensions and packing protection. Thin-wall or small-ID tubes need careful separation to avoid scratches, dents or edge damage. For machined tungsten tube parts, we can mark and pack parts according to drawing number or batch requirement when the order involves several sizes.
Because tungsten is dense and brittle compared with many structural metals, packing must be treated as part of the product quality. We use protective wrapping, trays, foam or wooden cases depending on the tube size and shipment method. This reduces avoidable transport damage and makes receiving inspection easier for overseas customers.
FAQ
What is the difference between tungsten tube and tungsten pipe?
In many purchasing requests, tungsten tube and tungsten pipe are used for the same hollow tungsten product. Tube is often used when the buyer cares about precise OD, ID and wall thickness, while pipe may be used for larger or process-related furnace parts.
Can you make custom tungsten tube from a drawing?
Yes. Please send the drawing with OD, ID, length, tolerance, quantity and surface requirement. We will review whether the size is suitable for manufacturing and quote based on the actual specification.
Is pure tungsten tube suitable for vacuum furnace use?
Pure tungsten tube is commonly selected for vacuum furnace applications because tungsten has a high melting point and low vapor pressure. The final choice should still consider working temperature, atmosphere, mechanical load and contact materials.
What information is needed before ordering a thermocouple protection tube?
Please provide thermocouple diameter, tube OD and ID, length, closed or open end requirement, furnace temperature, atmosphere and quantity. These details help avoid a tube that fits the drawing but does not fit the actual furnace.
