Matkap yakaları, AISI 4145h modifiye alaşım çeliğinin katı bir çubuğundan inşa edilen entegre bir ağır hizmet eklemidir. Standart matkap yakalarımızda “haddelenmiş” yüzey kaplama koşulu verilir. Tüm standart çubuklar, onlara gerekli mekanik özellikleri sağlayan ısı muamelesi alır.
Çubuklar daha sonra tetiklenir ve sürüklenir. Tüm matkap yakalarımız API Spec 7, Q1 ve önerilen uygulama 7G uyarınca üretilir. ASTM A519 Çelik Boru ASTM A213
