You can put the steel pipe inside of the lead and melt the lead to seal it. That's takes experience and some talent. You can join them with a rubber sleeve that is the right size on each end and held in place with hose clamps.
One cannot solder/ lead wipe lead to steel as one is ferrous and the other non ferrous metal You can lead wipe /solder lead to copper /bronze / brass To join to steel one had to lead wipe a brass nipple (called solder nipple) into the lead pipe and you have either male or female threads and then a union or left and right nipple and coupling to make a proper connection.''
By the way you cannot do a lead poured joint of steel into lead you can put the steel into a cast Iron hub and then use a caulked joint.
Also the use of a no hub or a mechanical coupling will not be good for a water or gas tight against a lead pipe as lead is to soft.
By lead wiping a brass nipple into the lead pipe and then using a F x PVC adapter to the male threads of the brass nipple.
It will connect to the PVC pipe into the wall which ultimately will connect into the main sewer line outside.
Lead wipe a brass nipple into the lead pipe and then use a female adapter x PVC on the brass threads
C x M adapter C x F adapter PVC x F adapter PVC x M adapter or Thread if your really using "pipe" in lieu of "tubing"
purchase a threaded connector, for the PVC pipe, then purchase a metal threaded adaptor for soft pipe, see your hardware man,
I would take out the lead bend and replace it with pvc.
You can't. There is no fitting to do this. Galvanized has to be threaded.
Male to female threaded adapters.
You can often find a modern connector such as Sharkbite or Qwest fitting to do this.
Abs to PVC glue sold at home depot Color it aqua blue/green plumbers key term. GUMBY GLUE Depends upon what you mean by "black pipe". If you mean ABS drain pipe, there is glue for that. If you mean steel "black pipe", i.e., non-galvanized, then you would need a threaded connection adapted to the PVC (either a female PVC connector on a male black pipe or a male PVC connector into a female black pipe fitting). The secondary question would be, "Why would anyone want do to that?"
I was in the PVC pipe manufacturing business for over 30 years and have never heard of a "1K PVC" pipe. If "1K" means a 1,000 psi pipe, this does not exist as a commercial product. Sorry.
When I have to connect copper to lead "D" I usually solder the copper to the lead or wipe a lead joint depending on the diameter To connect copper to cast iron ,.... If there is a hub I caulk the copper directly into the CI with oakum and poured lead (molten) OR one can solder / braze a female adapter fitting and screw the copper into a CI female fitting
