Sanitary & heating
Armatures, gunmetal and copper pipe from the SHK-operation – the questions from the trade.
In sanitary and heating construction, almost every order has a mixture whose parts differ widely in price: copper pipe, brass fittings, gunmetal fittings, steel radiators, cast radiators, occasionally lead pipe. The difference between a trough for everything and four containers in the transporter is greater in this trade than in any other.
This can be calculated in advance because pipe mass is standardised. Copper tube 15 times 1 millimeter weighs 0.39 kilograms per meter. The riser lines and distributions of a single - family house quickly reach 30 to 50 kilograms of copper — a post that is worth the way as long as it does not end with insulating wool and cast iron in the same hollow.
Casting radiators are the most common mistake. They are heavy, make volume and have a valuable effect, but remain iron scrap: per kilogram the old limb radiator brings a fraction of the copper tube that lies next to it. Those who load the transporter by value instead of by space, take first the nonferrous metal and then the steel — and hang a bucket on the wall for the fittings because small parts are what is lost on the road.
How do I distinguish cast red from brass?
At the color of a fresh wedge or interface: gunmetal looks reddish to salmon, brass yellow. At the shape: Gunmetal is cast material — valve body, pump housing, water meter, often with rough casting skin and cast seam, while brass is usually pressed, turned or available as sheet metal. Gunmetal sounds duller, and the fracture surface is grainy instead of tough.
How many times do you pick up?
From 500 kg, and the clock depends on your level, not on the calendar. With chips from ongoing production, these are often a few weeks, and with carbide it takes longer because the weight is stuck in a bucket. We agree to regular pick-up by arrangement. Depending on the distance between 40 and 350 euros, the pick-up costs are fixed before the trip.
Can I get a credit for the bookkeeping?
Yeah. We charge for commercial deliveries by credit in accordance with § 14 para. 2 VATG, so you do not write an invoice. VAT is not based on the fact that the recipient of the benefit owes the tax on scrap metal, § 13b para. 2 no. 7 VATG. In addition, the weighing slip of the calibrated scale with grade, weight and date; is paid within 24 hours.
Do steel spindles and iron cores need to get out of the fittings?
Where it can be done without much effort, yes. Steel spindles, pressed-in cores, pin screws and bearing shells made of steel make of tap brass mixed goods. The magnet shows in seconds what's still inside. Chromium-plated and nickel-plated surfaces work the same way, but cannot be removed; we sort them out during the evaluation.
Do you use copper pipe with soldering points and insulating wool?
Soldering points and small soldering tin residues at fittings do not change the grade, copper tube runs as copper Raff. Insulation wool, mortar and cement residues belong, and there is no water in the pipes, because it weighs with it and is not paid. Brass fittings better pull them out, they have their own, other daily price.
Do you take lead from the fireplace connection and old lead pipes?
Yes, we buy lead, lead sheets and tube lead. Clean soft lead brings the best proceeds, color, mortar and iron adhesions press the classification. Collect it in your own closed container. We do not accept batteries and batteries, lead exclusively as metal and not as a cell with housing and acid.
