Abstract
The utility model discloses a metal composite Y-joint, and is characterized in that the thick wall of the Y-joint comprises an inner metal layer and an outer metal layer which are fixedly connected with each other; the inner metal layer is made of stainless steel; and the outer metal layer is made of carbon steel. The metal composite Y-joint has the advantages of high strength and good corrosion resistance, thereby having a wide application range.
Description
Technical field
The utility model relates to a kind of metal composite tee union, especially for the metal composite tee union on the pipeline of transferring oil gas medium.
Background technique
Development along with modern oil-gas mining conveying technology; The transportation pipe line is more and more longer, and line pressure is increasingly high, in addition climatic anomaly in recent years; Former oil gas contains the hydrogen sulfide gas of a large amount of severe corrosives and severe toxicity again, and the Security of transportation pipe line has been proposed new requirement.Tee union in the common oil-gas pipeline adopts the pure carbon steel to make mostly, and it can satisfy requirement of strength, but poor corrosion resistance can't satisfy the needs of present stage.
The model utility content
The purpose of the utility model is the above-mentioned deficiency that exists to existing technology, and a kind of metal composite tee union is provided, and it has the advantage of intensity height, good corrosion resistance, and is applied widely.
For achieving the above object, the metal composite tee union of the utility model is characterized in that the wall thickness of said tee union comprises the inside and outside layer metal that connects firmly, and inner layer metal is a stainless steel, and outer layer metal is a carbon steel.
The utility model can process through the sheet material that the welding of inside and outside layer metallic explosive connects firmly, and inside and outside layer metal combines closely delamination can not take place; Outer field carbon steel has high intensity, its good corrosion resistance of the stainless steel of internal layer, and the metal composite tee union has the advantage of the two simultaneously, and is applied widely.
Description of drawings
Fig. 1 is the plan view of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
As shown in Figure 1, the wall thickness of this metal composite tee union 1 comprises the inside and outside layer metal 2,3 that connects firmly, and inner layer metal 2 is a stainless steel, and outer layer metal 3 is a carbon steel.
The utility model can process through the sheet material that the welding of inside and outside layer metallic explosive connects firmly, and inside and outside layer metal 2,3 combines closely delamination can not take place; Outer field carbon steel has high intensity, its good corrosion resistance of the stainless steel of internal layer, and metal composite tee union 1 has the advantage of the two simultaneously, and is applied widely.
Claims (1)
1. a metal composite tee union is characterized in that the wall thickness of said tee union comprises the inside and outside layer metal that connects firmly, and inner layer metal is a stainless steel, and outer layer metal is a carbon steel.
