First declare the pipe in the providers of your module:

import { YourPipeComponentName } from 'your_component_path';

@NgModule({
  providers: [
    YourPipeComponentName
  ]
})
export class YourServiceModule {
}

Then you can use @Pipe in a component like this:

import { YourPipeComponentName } from 'your_component_path';

class YourService {

  constructor(private pipe: YourPipeComponentName) {}

  YourFunction(value) {
    this.pipe.transform(value, 'pipeFilter');
  }
}
