Abstract
The utility model discloses a corrosion-resisting wear-resisting pipe joint, which is a welding multi-way joint. The inner surface of the pipe joint is uniformly provided with protective coatings (1). The pipe joint is made of stainless steel or carbon steel or cast steel. The protective coatings (1) are prepared from nickel-based cobalt-based iron-based alloy powder materials or nickel-based cobalt-based iron-based alloy flux cored wires. The thickness of each protective coating (1) is greater than or equal to 1mm. For the corrosion-resisting wear-resisting pipe joint, the inner surface of a pipe joint substrate is uniformly provided with the protective coatings, so that when a corrosive medium is transmitted by the pipe joint, the corrosive medium can be avoided being directly in contact with the inner surface of the pipe joint substrate, and thus, the corrosion-resisting and wear-resisting performances of the weld seam position of the pipe joint and the inner surface of the whole substrate are improved, and the service life of the pipe joint is prolonged. Meanwhile, the protective coatings are prepared from the nickel-based cobalt-based iron-based alloy powder materials or the nickel-based cobalt-based iron-based alloy flux cored wires, and thus, the corrosion-resisting wear-resisting pipe joint not only is beneficial for improving the corrosion-resisting and wear-resisting performances of the pipe joint, but also is beneficial for better fusion of the protective coating and the pipe joint substrate.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly relates to a kind of anticorrosive anti-wear pipe joint.
Background technique
Be used to connect the welding type multiple way union of steel pipe at present when the transmission special media, because its internal surface position while welding corrosion and wear resistance wearability is not high, its internal surface weld seam is easy to damage, often need in the operation process it is frequently changed, both influence normal operation and reduced operating efficiency, increased the user cost of pipe joint again.
The model utility content
It is simple and can improve the pipe joint usability greatly, prolong the pipe joint anticorrosive anti-wear pipe joint in working life that technical problem to be solved in the utility model provides a kind of architecture advances.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of anticorrosive anti-wear pipe joint, be the welding type multiple-pass joint, and the internal surface of described pipe joint evenly is provided with protective coating.
As preferably, the material of described pipe joint is stainless steel or carbon steel or cast steel.
As preferably, described protective coating is made by Ni-based, cobalt-based, iron-based alloy powder material or Ni-based, cobalt-based, ferrous alloy medicine core wire.
As preferably, the thickness of described protective coating is more than or equal to 1mm.
A kind of anticorrosive anti-wear pipe joint of the utility model; by internal surface protective coating is set evenly at the pipe joint base material; can avoid pipe joint Korrosionsmedium when the transmission Korrosionsmedium directly to contact with pipe joint base material internal surface; improved the anticorrosive anti-wear performance of pipe joint position while welding and whole base material internal surface greatly; increased its working life; adopt Ni-based simultaneously; cobalt-based; iron-based alloy powder material or Ni-based; cobalt-based; ferrous alloy medicine core wire makes protective coating; both help improving the anticorrosive anti-wear performance of pipe joint, helped protective coating again and the pipe joint base material merges preferably.A kind of anticorrosive anti-wear pipe joint of the utility model, architecture advances is simple, beneficial effect is obvious.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of anticorrosive anti-wear pipe joint of the utility model.
Wherein, reference character: 1 is protective coating.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As shown in Figure 1, a kind of anticorrosive anti-wear pipe joint of the utility model is the welding type multiple-pass joint, and the internal surface of pipe joint evenly is provided with protective coating 1.The material of pipe joint can be stainless steel or carbon steel or cast steel.Protective coating 1 is made by Ni-based, cobalt-based, iron-based alloy powder material or Ni-based, cobalt-based, ferrous alloy medicine core wire; adopt one of previous materials to form pipe joint protective coating 1 and both can improve its anticorrosive anti-wear performance; can guarantee that again coating and pipe joint base material merge preferably, thereby avoid it in use to cause coating 1 to come off.In order to guarantee the anticorrosive anti-wear effect of protective coating 1, the thickness of protective coating 1 is preferably designed as more than or equal to 1mm.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
