Frequently Asked Questions (FAQ)

Q1: What sizes and wall thicknesses do you offer for stainless steel capillary tubes?

Our capillary tubes are available in outer diameters (OD) ranging from 0.25mm to 28mm, and wall thicknesses ranging from 0.08mm to 1.5mm to meet precise industrial requirements.

Q2: Which stainless steel grades are available for capillary tubing?

We manufacture capillary tubes in a wide array of grades including 201, 304, 304L, 316, 316L, 904L, 310s, duplex steels (2205, 2507), and high-performance nickel alloys (Inconel 625, Incoloy 825).

Q3: Are the capillary tubes provided in coils or straight lengths?

We offer both straight and coiled options. Coiled tubes can be manufactured in continuous lengths ranging from 600 to 3500 meters without any welded joints.

Q4: What inspections are carried out to ensure the quality of the tubing?

All products undergo comprehensive quality checks, including chemical composition and physical properties testing, Eddy Current Testing (ECT), and Hydrostatic Testing.

Q5: What are the main industrial applications of stainless steel capillary tubes?

They are commonly used for dynamic instrument signal transmission, automatic instrument wire protection, precision optical systems, industrial sensors, electrical circuit insulation, and core support for high-voltage cables.

Q6: What surface conditions can you provide?

Our standard supply condition for stainless steel capillary tubes is a bright and soft annealed finish, ensuring smooth surface quality and ease of installation.
