Abstract
A stainless steel-lined double-flange welded composite pipe comprises a lining pipe (1) and an outer pipe (2), wherein the lining pipe (1) is adhered and fixed onto the inner wall of the outer pipe (2); flange plates (3) are welded and fixed at the two ends of the outer pipe (2); flangings (11) are moulded on the lining pipe (1); and the flangings (11) press against the end surfaces of the flange plates (3). The stainless steel-lined double-flange welded composite pipe is very easy and convenient to operate in the abutting process, thus improving the working efficiency and reducing the operating difficulty.
Description
Technical field:
The utility model relates to the composite pipe technical field, more specifically to the two flange welding of a kind of inner liner stainless steel composite pipe.
Background technique:
Be used to carry the pipeline of tap water to be generally galvanized pipe now, be prone to get rusty after galvanized pipe uses for a long time, galvanized pipe can polluted source like this.
The someone uses the inner liner stainless steel composite pipe to carry tap water now, and it is made up of internal lining pipe and outer tube, and internal lining pipe is generally stainless steel, and this sampling composite tube just is not easy to be corroded, and can increase pipeline ground working life, and the water source of avoiding being transferred is contaminated.Its deficiency is: during site operation, need the butt joint of two step welding process inner liner stainless steel composite pipes.The first step: with the Stainless Steel Tube sealing welding of two inner liner stainless steel composite pipes, second step: the galvanized pipe with two inner liner stainless steel composite pipes welds together again.Time-consuming, effort when such welding procedure makes the pipeline butt joint, inefficiency, construction is got up and is very bothered.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology, and the two flange welding of a kind of inner liner stainless steel composite pipe is provided, and it makes that composite pipe operation when butt joint is very simple, convenient, has improved working efficiency, has reduced operation easier.
The technological solution of the utility model is following:
The two flange welding of inner liner stainless steel composite pipe comprises internal lining pipe and outer tube, and said internal lining pipe is adhesively fixed on the inwall of outer tube, and flange plate is weldingly fixed on the two ends of outer tube, forms flange on the internal lining pipe, and said flange is pressing on the end face of flange plate.
Said internal lining pipe is a Stainless Steel Tube.
Said outer tube is a galvanized pipe.
The beneficial effect of the utility model is: it only need be fixed the flange plate on the two tubes when engaging two composite pipes, and it makes composite pipe simple when engaging, convenient, increases work efficiency, and has reduced operation easier.
Description of drawings:
Fig. 1 is the sectional view of the utility model
Fig. 2 is the right elevation of Fig. 1
Among the figure: 1, internal lining pipe; 2, outer tube; 3, flange plate; 11, flange.
Embodiment:
Embodiment: see Fig. 1, shown in 2; The two flange welding of inner liner stainless steel composite pipe; Comprise internal lining pipe 1 and outer tube 2, said internal lining pipe 1 is adhesively fixed on the inwall of outer tube 2, and flange plate 3 is weldingly fixed on the two ends of outer tube 2; Form flange 11 on the internal lining pipe 1, said flange 11 is pressing on the end face of flange plate 3.
Said internal lining pipe 1 is a Stainless Steel Tube.Said outer tube 2 is a galvanized pipe.
Working principle: in butt joint two basic model utilitys, only need be with flange 11 alignment of two basic model utilitys, with bolt the flange plate 3 on the two basic model utilitys being fixed together then gets final product.
Claims (3)
1. the two flanges of inner liner stainless steel weld composite pipe; Comprise internal lining pipe (1) and outer tube (2); Said internal lining pipe (1) is adhesively fixed on the inwall of outer tube (2); It is characterized in that: flange plate (3) is weldingly fixed on the two ends of outer tube (2), forms flange (11) on the internal lining pipe (1), and said flange (11) is pressing on the end face of flange plate (3).
2. the two flange welding of inner liner stainless steel according to claim 1 composite pipe, it is characterized in that: internal lining pipe (1) is a Stainless Steel Tube.
