1. Idizayini Ehlangene:Amaphayiphi amapayipi aminyene ngokwedlulele futhi angafakwa ngokuqondile kumapayipi, awadingi isisekelo esengeziwe noma indawo enkulu yokufaka. Lo mklamo ohlangene wenza ukufakwa kube lula kakhulu, okwenza ukwakheka okulula nokongiwa kwendawo kukho kokubili ukwakhiwa okusha nokulungiswa kwamasistimu akhona. Isibonelo, ezinhlelweni zokudonsa amanzi ezingaphansi ezakhiweni ezinendawo elinganiselwe, amaphampu amapayipi avumelana kahle futhi asebenza kahle.
2. Izinyathelo Ezincane:Ngenxa yokwakheka kwazo okuhlangene, unyawo lwazo lulonke luncane kakhulu kunezinye izinhlobo zamaphampu. Lokhu kuyinzuzo ephawulekayo ezindaweni ezinezinsiza zomhlaba ezilinganiselwe noma izimfuneko zendawo ezibalulekile, njengezakhiwo zezentengiselwano ezisemadolobheni amakhulu nasezindaweni zokusebenzela zasefekthri. Bangakwazi ukufeza ukudluliswa koketshezi okusebenzayo ngaphakathi kwesikhala esilinganiselwe ngaphandle kokuphazamisa ukwakheka kwezinye izindawo ngenxa yokwakheka kwazo okukhulu.
