On a system built in that size, a corner and a joint become the same component — no separate sleeve, no butt weld, and one less thing to align.\u003c\/p\u003e\u003cp\u003eIt is a small saving on a single corner and a real one on a run with four of them.\u003c\/p\u003e\u003ch2\u003eRare in a Catalogue\u003c\/h2\u003e\u003cp\u003eFifty-two is a size most suppliers skip. Bending it requires its own mandrel and its own die, and the volume does not justify the tooling for anyone building to round numbers.\u003c\/p\u003e\u003cp\u003eSpark keeps it because its own systems use slip joints throughout, and a slip joint needs a female half. That decision at the factory is what puts the article in the catalogue.\u003c\/p\u003e\u003ch2\u003eRadius at This Diameter\u003c\/h2\u003e\u003cp\u003eThe centreline radius of a production bend is set by what the tooling can form without distorting the section, and it grows with diameter. A fifty-two millimetre bend therefore sweeps wider than a forty-millimetre one at the same angle — something to allow for when the run has to clear a shock or a footrest hanger.\u003c\/p\u003e\u003ch2\u003eWhere the Angle Fits\u003c\/h2\u003e\u003cp\u003eThirty degrees is a correction rather than a corner. On a large-capacity machine with a long run to the silencer it is usually the last piece: the collector points one way, the mount is somewhere else, and a shallow lean reconciles them.\u003c\/p\u003e\u003ch2\u003eEngagement Depth\u003c\/h2\u003e\u003cp\u003eWhen a fifty millimetre pipe goes into this bend, give the joint sixty to eighty millimetres of engagement. The straight tangent on a bend is short, so most of that overlap has to come from the pipe being pushed in rather than from the bend itself.\u003c\/p\u003e\u003ch2\u003eHolding the Joint\u003c\/h2\u003e\u003cp\u003eTwo springs at opposing sides, which is how Spark holds its own. A band clamp works too and fights the thermal movement that the spring allows — on a run of any length the spring is the better answer.\u003c\/p\u003e\u003ch2\u003eOrdering\u003c\/h2\u003e\u003cp\u003eOne bend per article. Spark builds 30°, 45° and 90° at this diameter.\u003c\/p\u003e","brand":"Spark Exhaust","offers":[{"title":"Default Title","offer_id":53618101846282,"sku":"G9150","price":129000.0,"currency_code":"KHR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/6087df6d88cc6_bccbd1ba-1f15-4dbc-90cf-447662229dd0.png?v=1788347461","url":"https:\/\/inter-pace.com\/en-kh\/products\/spark-exhaust-bent-tube-30-degrees-52mm","provider":"Inter-Pace","version":"1.0","type":"link"}
