Product Details

304 stainless steel is widely used as a kind of chromium - nickel stainless steel. As a widely used steel,its characteristic is corrosion resistance, good heat resistance, high strength in low temperature, easy to process on punching, bending and other thermal processing, non hardening heat treatment (when temperature is -196℃ to 800℃), Corrosion resistant in the atmosphere,if it is in the industrial atmosphere or heavy pollution areas, you need to clean in time to avoid corrosion.

We are reckoned for the supplying and trading of a gamut of best quality s s 304 Welded Pipes & Tubes. The offered products are widely regarded for their sturdiness.

FAQ: The 304 stainless steel decorating pipe.

Generally, the decorating pipe means the surface of pipe must be 2B or HL because the decorating pipe is mainly used in outside areas. In our daily life, most of the stainless steel pipe we can see in city are decorating pipe.

 

304 Stainless Steel Pipe Welding Technology Summary

1. Process Flow

Construction preparation → material entry, inspection → blanking → discharge line, supporting hanger installation → welding → weld seam polishing and pickling passivation treatment → weld inspection → pipeline irrigation test, flushing

2. Operation Essentials

2. 1 Construction Preparation

(1) Compile construction plan and construction schedule, set up quality work standard.

(2) operators to pipe workers, argon arc welder mainly, other types of cooperation, and argon arc welder should have the relevant departments issued a certificate.

(3) Construction materials according to the material plan, sent to the scene, and ensure the supply according to plan.

(4) On-site operators to carry out written technical clarification, on-site technology, safety disclosure.

2. 2 Welding Material Preparation

(1) The selection of pipe and pipe fittings should be based on the use of environmental media factors, chemical composition and the use of pressure, and the appropriate grade of products to ensure that the weld metal microstructure and mechanical properties.

(2) Argon gas should conform to the national standard "argon" GB4842, should choose the purity of 99.96% argon, if the impurity content too much, will weaken the Argon gas protection effect, directly affect the weld quality.

(3) Electrode material is cerium tungsten pole. The shape and diameter of the end head of the cerium-tungsten pole have a great influence on the stability of the welding process and the weld forming. Conical flat end effect is best, see Figure 1.1. Tungsten Electrode is selected according to the welding pipe thickness and welding current size, and the welding technical parameters are shown in Table 1.1.
