Specification

Standards for Monel 400 Tube

As long as our tubes meet ASTM B163 (seamless) and B165 (seamless condenser) standards, they are the right size and will contain the same chemicals. They also meet ASME SB161/SB163 for stress tubes.

What are the Features of Monel 400 Tube?

Monel 400 Tube is well-suited for marine settings because it resists chloride attack. Hydrofluoric and sulfuric acids don't hurt it, and it stays flexible at very low temperatures. At high temperatures, it sets in steam. Its balanced nickel-copper chemistry keeps it from wearing away in fast-moving seawater and makes it simple to work with when setting up complicated systems.

Application

Marine engineering includes pipes that carry seawater, splash zones on ocean platforms, and heat exchangers that don't get biofouling or rust from standing water.

Chemical Processing: HF alkylation units, brine evaporators, and working with chloride vapors and salts that are boiling.

In the energy sector, there are boiler feedwater heaters, crude oil distillation towers, sulfur compounds that don't break down, and high-temperature steam that doesn't weaken.

Production and Processing Technology

At TSM Technology's 60,000㎡ plant, vacuum melting is used to check the quality of raw nickel-copper alloys. To get tight specs (±0.05 mm), seamless tubes are hot-extruded and cold-drawn through more than 100 high-precision tools. When you anneal at fixed temperatures, the grain structure stays the same. With 8 production lines, we can make 300 tons of products every month, and we can make them any size, up to 15 meters. Each batch gets full documentation that shows how it was made.

Quality Inspection

We use strict testing methods based on ASTM B163 guidelines:

Chemical Analysis: ICP and OES check the limits of makeup

Tensile, yield, elongation, and flattening tests were done according to the requirements.

NDT uses ultrasound (UT) and eddy current (ET) to find flaws inside and on the outside of a product.

Hydrostatic Testing: Making sure the pressure stability is correct

Checks for Dimensions: OD, wall, length, and straightness are all checked.
